In an exclusive interview with paultan.org, Proton chief technical officer Abdul Rashid Musa has shared some key details regarding the national carmaker’s highly-anticipated new engine family – announced earlier this month – which will utilise direct injection and will be offered in both naturally-aspirated (GDI) and turbocharged (TGDI) variants.
Firstly, the development of the new engines were driven by regulatory and market requirements, as Proton wants to be a competitive global player – and with the European market now requiring all new cars to meet the stringent Euro 6 emissions standards, the company needs the new mills (which are designed to meet Euro 6c regulations coming into effect in 2018) if it ever wants to return to the lucrative Continental market.
Rashid said that Proton needs to change and upgrade its capabilities to be more competitive. He admitted that the company was late in introducing variable valve timing (VVT) technology – which only came onto the market with the Iriz at the tail end of 2014 – but added that the company is catching up to established players.
As was revealed during the official announcement, the new engines are modular, with commonalities both in design and the components used. The 1.3 litre and 1.5 litre GDI and TGDI engines are four-cylinder engines, sharing an identical bore but differing stroke measurements; the 1.0 litre and 1.2 litre VVT engines are three-cylinder versions of those four-pot mills.
The engines feature a higher compression ratio of 12:1 on GDI engines and 10.5:1 on the TGDI engines – these compare favourably to 10:1 on the Iriz’s VVT engines and 8.9:1 on the 1.6 litre CamPro CFE/Turbo engine. Also incorporated is a split engine cooling system that enables the cylinder head and block at different temperatures for optimised efficiency. On TGDI engines, a single-scroll turbocharger is used, with the most powerful 1.5 litre TGDI projected to be capable of producing 180 hp and 250 Nm.
Elsewhere, the fuel injectors on the GDI and TGDI engines are capable of spraying fuel at 200 bars of pressure, compared to just 2-3 bars in a standard port injection system. The technology used on the new GDI engines are based on the patents obtained from Petronas when it acquired the oil giant’s engine technology in 2012, some of which are shared with development partner Ricardo.
The engines are also designed to be future-proof, with features like cylinder deactivation (using a collapsible roller finger follower), mild hybrid operation (through the use of a belt starter-generator), a Miller cycle and spray-guided direct fuel injection able to be added on.
The workings of a Miller cycle engine would require a separate article to be explained fully – but essentially, in such an engine, the intake valve is left opened for part of the compression stroke, which pushes some of the air/fuel mixture back into the intake port. This reduces the effort required to compress the remaining mixture, aiding efficiency.
On the other hand, spray-guided direct injection, which uses injectors mounted at the top of the combustion chamber to spray fuel downwards – rather than from the side against a walled chamber in the piston in traditional systems – results in improved fuel efficiency. The aim, according to Rashid, is for the engines to eventually achieve a thermal efficiency of almost 40% – the same as on the newest hybrids like the Toyota Prius and Hyundai Ioniq.
Rashid said that while Proton isn’t a technology leader, it wants to bring these technologies down towards a more affordable level – as it has done in terms of safety. “The technologies aren’t cheap, but we are contributing significantly in making them more affordable,” he said.
Looking to sell your car? Sell it with Carro.
Future-proofed? Read between the lines.
It’s telling you that this engines are going to stay for the next 20 years.
vios engine is 3 generation in use and will continue to be in use until 4040.
“Rashid said that while Proton isn’t a technology leader” BUT Proton leading in self praising statement that’s fact !
Come and get free ikan panggang. Free for buyers.
Dare to buy this new engine ah? Don’t forget the Exora that bakar going up genting. You get free death and free cremation. 2 in 1 package.
Best part, Proton told the owner to podah and refused to layan him.
So many other Exora bakar, Proton just cover up.
You still dare to use new engine from Proton?
Fellow use Rm40k Panerai watch. Sure get free one. DRB Hicom always get a lot of free gifts, if you know what I mean.
Technology aren’t cheap because of Proton’s bloody protection and government heavy tax!
Check out the Prius price in Japan and US then you know what I am saying.
Proton can’t develop good engine then blame others, old tradition!
Slandering here and there, duh. Where got deaths in Exora “cremation”?
He ady got money from insurance company.
Now Proton staff like this CTO pakai baju DRB Hicom. They are one with DRB Hicom. But even in private hands, still ask money from our Government. Hundreds of Millions per year to keep it float.
Back in 2008, the CEOs of GM, Chrysler, Ford went on their private jets to White House and demanded for Gov money otherwise they kolos shop and move all to Mexico. Nobama said, okay here’s ur money.
Yes they asked money. They have been making money and pay taxes before 2008. After they got the money in 2008, they got out of trouble and making money within a short period of time.
Now back to you. Where is Proton now?
P1 din get any sen from Najib, the last I heard. Thats why Tun M went on warpath
Why not if the engine is reliable and fuel efficient, what’s the use if so much technology yet rosak here and there and makan minyak? Think again…
VW, honda, toyota, peugot, mercedes, bmw etc also has rosak here and there. Name one car company in this entire universe that is rosak free.
So what? if it’s modular enough to be tweaked for future requirements, all the better! That’ll mean it can be a sunken cost faster, which will help towards reducing production costs over the long run. Do you think engines are supposed to be like computer CPUs that need a new generation of microarchitecture every 24-36 months? Look at Mitsubishi’s 4G6 engine family.. they were around for ages before being superseded by the 4B1 series. Same goes for Honda and Toyota engines.
Come on. Give him a break. He is one of those ‘certified’ Proton haters.
Even if the engine somehow get world best engine also would not be enough for them. All they ever want from Proton is to close shop, for whatever benefit it may bring to them.
before anyone yelling “what? single scroll only? ancient turbo!”, most Ford Ecoboost engines have single scroll turbos. Some of them even have the same old BW KP39 unit found in the CFE. Twin-scroll turbos are just expensive shortcut tickets to make up lazy-ass exhaust manifold design.
agreed, even more impressive this engine produce more than Honda’s 1.5l output. next challenge – drivetrain.
Honda making good output with efficient engine, hope Proton can compete with that.
Above all, safety must remain 1st priority.
Safety aspects no need worry bcos currently offer already far better than Perodua and Vios.
What? Engine offer safety? like what? You engine tried to kill a family by burning an Exora got la.
Never go full retard
He ady retard lor
Fulamak, you know how to use the word retard la. Not bad for a tiga suku engineer.
Shut up and take my money? Hahaha
Mengaku ajelah kata tak pandai buat enjin, jangan buang masa, beli enjin jepun je, sales pasti improve,think again, hadapilah kenyataan…
Proton Perdana 1.5 TGDI
the latest kuga (1682kg) on sale is powered by an 1.5 TGDI ecoboost engine…180 bhp , 240nm of toque…
the accord 8th gen-based perdana should weigh much less (give or take 100kg) , performance shubbe sufficient..
wether it’ll be a refined and relaxing drive , is yet to be seen…
as per usual, proton will continuously update their line up bits by bits as time goes , so the 2018 perdana TGDI would definitely drive better, has better NVH, interior trim than the upcoming 2016 2.4 perdana….
like how the brown interior waja was miles ahead on the inside compared early models…( not forgetting the early waja had massive recalls due to some components missing or something )
only time will tell, but very likely proton will succeed and will go global…
Do Proton have time on their side?
Don’t forget TDM is very old already.
What has TDM’s age got to do with anything? Will YTL close shop if Francis Yeoh died? Did the Genting group collapsed and closed shop when Lim Goh Tong died?
Memanglah semua nak improve time to time, tapi current engine pun tak mampu nak buat dengan baik….kena pandai merangkak dulu baru berjalan, kena pandai berjalan dulu baru berlari….. proton ni ingat nak berlari di arena antarabangsa sedangkan masih dalam tahap berjalan aje, nak succeed global?
Compression ratio 12:1 on this GDI, sweet!
Unfortunately Malaysian dunno what is that, Malaysian only know 0.10/km which is that unit dunno is save fuel or save cents
Unfortunately it wont achieve that compression ratio most of the time since the miller cycle actually reduces the compression ratio to “save fuel”.(or in some cases, reduces knocking)
Finally, found somebody comment on the specs of the engine.
I was seriously looking on someone to comment on the compression ratio of the engine and I am seriously curious and wondering how do they do it. Does the engine designed for RON97? Or do they design the engine like how mazda did to their Skyactiv.
Honestly, this is the comment I want to see. Not some bashing comment about kereta mana bagus, keranda bergerak. I mean come on laa. Cant u guys just for once discuss something knowledgeable instead of hating.
Back to the engine, 12:1 CR is seriously high for NA engine. Only Skyactiv manage to do that. So we can expect that the engine will come out with Scavenging Exhaust Manifold like the one in Skyactiv.
I’m seriously interested on this engine design now.
Let’s hope somebody in this blog read your comment. Hope we can be like the German where engine technology is well discussed.
12:1 at first but with the miller cycle itll probably drop below 10:1 because of efficiency reasons ( ie engine too hot…)
U think the average basher knows whatcha talkin about kah? They just bash cuz its P1 thats all.
bang balik tidur lah. Jangan bangun. Isnin boleh bangun
Good effort from proton. But the GDI and TGDI are just playing catch up since many other manufacturer have already done it. Its a shame that proton doesnt want to include aluminium block into it. Proton achilles heel now is its fuel consumption, much of it cause by its higher weight compared to other manufacturer. Therefore, focusing on engine alone is not enough. To be competitive esp in euro market, the prime focus should be FC, CO2, and designing the engine and chassis towards that.
Alu block actually have minimal impact on weight. Because to achieve high specific power, you need strong combustion chamber structure. So Alu Block need to add a lot of reinforcement to deal with it. Iron block can withstand high specific power easily.
VW 1.4 Twincharge also Iron Block.
Iron -> Alu Block weight saving is more relevant on big engines (more than 4 cyl)
Aluminum block does not dictate fuel economy. If the engine block is lighter, it doesn’t mean it will be more frugal. Typically an engine doesn’t even make up 10% of the total car weight. They will need a more efficient head design that ensures a more complete airfield mix so that the single lambda sensor can detect a stoichiometric mix consistently without the mix being actually slightly richer. A good lump of low end torque would be nice so that the CVT can keep the engine spinning at low revs most of the time. Lean burn at idle would be great for stop and go traffic, complemented by auto stop-start tech. All these would certainly make a difference, unlike an aluminum block alone.
Haha… what a joke. They can’t even get their existing crap engines lineup to be durable (how about not burning engine oil in your CFE huh Proton?) they want to talk about all these high tech thingy?
Please lah, learn to walk before u can fly. Right now you are barely walking. These upcoming high tech engines will be in the workshop every week ah.
If the French eg Renault engines are so troublesome despite their long time history, what makes Proton think they can be better than the French?
If they are that good they won’t be awarded kampong car mnaufacturer and still asked for protection after 31 yrs in the biz la…
And they would have at least sold ONE car in Singapore from 2014 till now la.
hey ss427, French cant do it doesnt mean Malaysian oso cant do it.
talk only with perception, not a single fact given.
He got jelly coz his jepunis car got tarpaued by Preve Turbo
The fact is that sales keep dropping, apasal?Engine and gearbox tak reliable… makan minyak, vibrate, not consistent…
Totally agree, however they pretend do not know… the only way is to just let the sales drop until it cannot sustained itself,if not tired advising also no use, fall into deaf ears…
Cant we be the pioneer on something? Why must we always be the one who follows?
Sure got a very bad history with their current production car which using very old technology.
But right now they already start the changes.
Honestly, instead of worrying the developing technology, dont u think its better to worry about why they announce about the engine soooooo early?
Honestly as a 25 year old man who are very enthusiast in car and currently looking for one. I would wait till the new engine is released. Which means no new car till 2018.
And what if most of proton potential buyers would have the same kind of thinking as me? Wont the sales going down the drain for straight 2years? And how do they going to pay salary to the staff? If the government gonna bail them out, that means more of our tax money going to waste. Now this is the real thing we should discuss
Paultan.org likes giving extensive coverage for proton with multiple articles in one go and always talking about how great proton is but when it comes to picking their best cars of the year only one mention of a proton made car.
Seems to speak volumes of the extra attention given to proton.
Aaaaannnndddd in their selection, do u find any moving coffins?
Sadly Proton still low sales no matter how much pusher done.
Noone forces you to buy it
Of course sales do not improve because proton pushing the wrong thing… always see themselves par with toyota, honda,nissan whereas are actually behind 15 to 20 years, example nak buat hybrid, engine petrol pun belum pandai nak buat, nak buat turbolah, gdi lah, tsilah, last last nothing succeed…. kena beli engine honda fit dlm perdana, this way only sales boleh improve…
PROTON ni LOW CLASS compare jenama besar buatan japan mcm TOYOTA……
ATAU…..
Malaysian (terutama yg kutuk proton kat sini) LOW IQ compare to japanese?????
Hati2 bila beri komen…jangan sampai kita sendiri tunjuk kebodohan kat orang luar…
Seluruh dunia dah tahu orang malaysia banyak ketinggalan berpuluh tahun dalam teknologi berbanding orang2 japan..
TAPI…
Janganlah buat seluruh dunia tahu yang kita kekurangan rasa nasionalisma berbanding orang2 japan..
SEBAB
Orang yang tinggi rasa nasionalisma jer yang mampu raih teknologi…orang yg takda rasa nasionalisma tak sanggup susah demi negara..lebih mengharap beli teknologi dari luar…
So true. Shameful those bashers
Yep German and Japan was Pro-Nationalist people….that why they achieve great thing…they put national interest ahead than personal….the problem with malaysia is everyone take care their personal interest than everyone good..
Turbo for what? Why must p1 not in line with proven sushi’s model line up’s such as jazz,city & vios for 1.5cc,civic & altis 1.8,2.0cc? Y must be different than others if ur not the lead brand..P1 for all kind of cc for all kind of model & engines type.. Such a waste.Simply create a model & slot in stupid engines.. Oi P1.. i teach u here.. Saga u put in 1.3&1.5..,Supirma put in 1.5&1.8,… Preve 1.8&2.0… No need turbo ..People need a vehicle that very fuel efficiency,no matter how cheap the crude oil per barrel sunk now.. Those idiots at putrajaya wont sell u 50cent per liter lor.. Next 2-3 years the price gonna skyrocketing back to usd90-100 per barrel then 1 liter will be 2.25 -230 per liter.. Again,subsidy will be blamed.. Now even no more subsidy also they said Petronas earn like a bird shit,tax so low.. so can’t lower fuel the price.When the oil is cheap usd28-30 they don’t sell cheap fuel,still hovering 1.80-1.95.. When the oil touch usd70-90 per barrel they increase the price per liter..believe me rm2.10-2.20 per liter again.This is the time malaysian paying 1.30-1.50/liter.. Gov already save 20billion on subsidy,why blame petronas for lower tax? U got gst already ma,.. Just cut your family’s worldwide spendings.. Malaysian will be saved.
Turbo on spendings(Bn gov) = useless benefits(proton)
The market in Europe is quite different to those in Japan. That is why Honda city, jazz, vios and Mazda 2 all still using NA engines.
But the trend for downsized turbo engines has been going around in Europe since a decade ago.
Fiat even has 800cc 2 cylinder turbo engine in the Panda. Seat benefitted from VW turbo engines…the same goes to peugoet, Ford and BMW.
Take note with the new engine line up proton will have 4 different types of powerplant, but all sharing same bore size. Meaning the possibilities of having same piston, rings, valve and springs.
Even your toyotaik company which you worship everyday everytime sells auris with turbo engine. Oh and that’s AFTER p1 intro CFE ok?
Haha!
Turbo my foot… makan minyak dan tak reliable, proton ingat dia boleh saing BMW, hakikatnya katak di bawah tempurung, pahamlah…
Proton is like Donald Trump. Stupid, expired, but soooo entertaining!
“Back to the continental market” HAHAHAHA JOKE of the year so far in 2016 hahahhahahahahahha
Petronas patent, petronas technology, petronas engine, petronas petrol, petronas oil, petronas petronas petronas. Adooiii Proton get a room la with Petronas
Which one is the car company again??? Ever heard of BMW/VW buying engine from Shell? Ever heard of Renault buying engine from Total? farrnyyyy so funny la.. omg
Keep up with the jokes bro.. we are enjoying it.. at least 2017 until you are bankrupt. Also can enjoy Kambing and Aero here writing 1000-word Pulitzer prize winning essays in support of Prowrong. Ah.. good times…
In its 40 year existence.. has Petronas ever collaborated with Proton on anything.. Damn bro.. your own Malaysian company also dowan to have anything to do with you.. have to go fell-atio with Suzuki la..VW la..Ricardo la.. hahahaha
That’s what losers have in their brains. They are losers and tell other to be loser too
I’m a taxpayer. Come talk when Proton is no longer taking my money.
Dont want govt/proton take your money(tax)…go to singapore or china idiot..
I have one word for you proton. Closeshoplah
Dun blame others for your failure in life.
P1 should know long time ago to be a success car brand in term of unit sold,they can’t depend just on Malaysian market.U spent hundreds of millions for just 1 model for r&d,then sell to local/typical Malaysian.. Sigh!! Build a durable&reliable car,good engine&fuel efficiency,..nice design!! Then sell to 3rd world countries (bangla,india,indochina,africas..) then try to bring back to old britain & Australia like before.. Sell outside Malaysia then u will not complain just making profit 500 per car!!! Are u listen DRB? Build a 5 star rating car like Iriz (re-do the back bumper)+good fuel consumption engine+durable+reliable then u can enter Europe.. no more plastics all over the interior & build lower 3-4 star for 3rd world countries..How long u want to depend on Malaysian to buy P1 if we afford to choose other brands?(rich even high gov tax or buy P2,we dare to be high household debtors)
that’s what Proton is trying to do now, with the new generation of vehicles. They know they can’t depend on the Malaysian market alone.
When Proton try to sell to Indonesia, bashers bash. When Proton inked agreements with Bangladesh, bashers bash. When Proton exported to Chile, bashers bash. But when Proton sell new models locally, bashers ask to close shop. Luckily, Proton and other local industries do not dance to the tune of these anti-government anti-Malaysia morons, otherwise the country will be worse than Zimbabwe before we know it.
Naaah. At least Zimbabwe has a central Gov. I wud say if Party Hard takesover, we be more like Somalia where each party has their own fiefdom Like those states under them now
Dont buy proton other than wira. Mine still running good with cheap maintenance. Other model with feel like junk after 5 year.
Please buy other than proton. They only tell you about engine only but overall material like it came from 18 century
*will
Clearly you don’t own newer p1 line up cars
GDI application sudah manyak lapuk since years and years ago.
Proton baru mau pakai??? They must be living in caves, izit?
12:1 compression ratio!??? Is that for real!?
Not bad…
najib’s cybertrooper is everywhere..
Proton is like having a drug addict in your family….you hate/angry/piss off/frustrated with them…but at same time you want them to turn good and become somebody useful to the public. So what can i say??….just kipidap…dongibab.
I’m loving these new articles which go into details of engine technology, learning a lot from these. Please keep it up, not just for proton but for other cars too! :D
Reading the kind of information they’re disclosing makes me wonder: If Proton is serious about exports why is their focus point on the new engines “it can produce ‘so-and-so’ horsepower/torque”.
They should really start focusing on fuel-efficiency which foreign markets are concerned about. Instead, the first thing they do is chest thump on theoretical max power outputs?
Come on…at least talk about some indicative MPG figures even if theoretical at this point, it shows your focus and direction of the new powertrain line up. Manufacturers around the world have long emphasised on economical engines with improved efficiency even at the trade off of some power.
for exora. please go and touch the radiator fan relay after running for 30mins. very very hot. i means is hot. feel like will caught fire. i check all other car. it is cool….dangerous or design problem?
whats the story now about this new engine….its already 2018 bruhh
