My first post here, just wondering if anyone has seen or knows of one

of these Quasiturbine Engines actually working as a Gas Engine. I've seen

the demonstration on Quebec TV, and they ran it with compressed air.

Quadsiturbine? Listen to them is so fun, especially when they talk about how good the fuel economy this thing will be. But until one working model fitted on a car, dont expect anything yet.

Fuel efficient engine? Try VW eco-racer. At least its more realistic then a quadsiturbine

But for so many year haven see waja 1.9turbo diesel.

I think the problem is malaysia diesel car road tax make people didnt think about diesel car. so proton didnt plan to sell this model.

Best diesel engine from japan is isuzu, in the past, honda civic use isuzu engine on europe market.

for europe small car diesel engine should be renault.

Proton wouldn't have to be talking to Bosch…

mileage? it may be 1.3L but the FC is even worse compared to a 4 cylinder 1.3L engine.

Still wankel engines potential have yet to be fully realised. Mazda RX-7 FD first started out with 280ps turbo'd wankel now 250ps on RX-8 NA configuration. The Mazda engineers will have to find ways to lower fuel consumption if they want to introduce wankel to their entire fleet (i forgot where i read that from). For now, drinks petrol like water and for ppl where petrol is like spending candy on a baby..cheap.

quasiturbine looks to be a promising technology but too many moving parts in the watever-u-call-it cylinder. at least the rotor inside the wankel rotary engine is a single piece component. with the quasiturbine's multi hinged "cylinder" expect some fantastic catastrophical failures lol.

tho its an interesting invention but hardly attractive for mass production.

"Wankel engines are gas guzzler" Thats exactly what im trying to tell him.

But The Quasiturbine Engine is in deferent case. However, The Quasiturbine Engine will take decades just to match our modern piston engine, according to howstuffworks.

Here are the quote from howstuffworks:

"The Quasiturbine may not be a competitive engine technology for decades."

It is a known fact that rotary engine cant match piston engine in term of torque and also efficiency.

But who know, in the future this may change. But i still think that its hard for rotary to match piston in term of torque.

Is it viable in the near future or is it just the engineers wet dream?

The Quasiturbine is similar to a Wankel but instead of having 3 chambers, it has 4. Really cool stuff man! Still in development. Check it out at:

can anyone explains the detail of Rexton diesel engine. is it using high tech diesel engine or some old tech engine. sorry, but i tak ingat which model.

my jiran owns one and everytime the rexton is started, the smell is so foul la… i kena tutup all the pintu and tingkap.

You very long winded but fantastic stuff and full of information. Didn't know can learn so much here. I thought this place only for bashing of national cars aka Proton!

Keep up the good work and don't worry about what KY jelly said. I'll still read your posts.

" if you really want to get value for money, get a Wankel engine". Are u kidding?

"or better yet, wait for the Quasiturbine to come out.". Can u please explain a bit or give some link, im a bit lazy to search the internet.

Heck, the current piston operated engines, diesel or petrol, are inefficient. No matter what modernized parts are put in, thye are still inefficient. So I guess we will have to make do. As for the environment and all that, I share your concerns. But at the same time, I care about the "thickness" of my wallet too… Driving a petrol engine car is causing premature thinning of my wallet! At the very least, diesels will keep my wallet plumper for longer.

La, if you really want to get value for money, get a Wankel engine or better yet, wait for the Quasiturbine to come out. That engine is DA BOMB man! Can use spark plugs but the best version is photo-detonation! No spark plug required! The fuel-air mix is compressed until self combustion happens. So, no fuel is wasted e.g. sent out in exhaust gasses.

Its still a new thing but hopefully, we will see it soon…

YAU MOU GAU….CHOR!!!

all black colour.. i watch in tv last nite..

sorry off topic

Sorry guys, got carried away.

Btw,

well… the best low sulphur diesel that is extracted from our country is sold to foreign country edi la… all left is we buy lousy high sulphur from saudi arabia lah….

———————————————————

Is that true? I mean, I though people extract crude oil/petroleum, and after that it would be distilled/processed to become the different oil types, instead of straight away extracting low sulphur diesels. To be honest, I think it USED to make sense to export good quality petroleum, and import inferior quality petroleum. Since there wasn't a huge demand of good quality oil in Malaysia, why not export it to give extra cash for the country. But I think it needs to change already, as people nowadays have more environmental awareness etc. Furthermore, it sickens me to think that any extra cash MIGHT actually go into some corrupt politician's pocket instead of being used for the country's good. I might sound cynical, I am…I've given up trusting Malaysian politicians now, be it the national front, or any opposition party. Monkeyboy, I agree with you, ALMOST all decisions made must have a hidden agenda behind it. Sucks, doesn't it?

I know I can just speak to you about this tomorrow morning, but what the heck…

The stigma all these while about diesel being bad for the environment and all were true. But that doesn't mean it's any better to use petrol. Both types of fuel give out bad emissions, but diesel gives a more noticeable product, i.e. thick black smoke. That black smoke is actually highly concentrated unburnt hydrocarbons. The content of petrol emissions is less of unburnt hydrocarbons, but alot more NOx, as petrol combusts at higher temperatures. Yes, the thick and black unburnt hydrocarbons can give a direct effect on respiratory systems, especially towards younger people. But NOx can give other bad effects, especially smog/haze as there is a chemical reaction occuring in the atmosphere bla bla bla… (some scientific crap that I'm sure alot of people wouldn't bother to read). Basically, just because people can see and smell diesel engine's emissions, and can't see petrol engine emissions, doesn't mean petrol engines are better. That is why people are spending shit loads of cash in improving both petrol and diesel engines' emissions.

People always knew that diesel engines give high power outputs compared to petrol engines, especially at lower revvs, (that is why diesel engines use turbochargers, so that the power output at higher revvs can also be huge) The problem they had was from emissions point of view. The technology and knowledge available in producing efficient petrol engines with low emissions has been around for quite some time now. But it is only recently that researchers have found out ways to improve emissions for diesel engines. That is why there is a sudden boom, if you like, about the benefits of diesel engines etc.

Because diesel engines use direct fuel injection and compressed ignition, the use of Computational Fluid Dynamics (which have only been available very recently) have made a big impact for people to understand the flow structure inside the diesel combustion chambers, which affects the efficiency of the combustion process. Now they've understood it, they can design the cylinder heads and pistons to produce optimum flow structures for combustion. Also people have produced better ways of fuel injection, eg. the Piezo Injection (do you guys have any clue what Piezo Injection is and what it does, or are you guys just quoting websites?). In all, they have now produced more efficient diesel engines that is more environmental friendly.

Yes, the quality of the diesel oil available also plays a big part in the engine's operation, but I think it affects reliability issues, more than it affects performance. As in, if you use low quality diesels, your engine needs to be serviced more regularly, your catalytic converter needs to be replaced maybe earlier than the specified period etc.

Monkeyboy, probably the kid you were talking about came close to an old lorry with a f*cked up engine, that is why it affected the kid's breathing badly. New diesel engines, such as the Honda CTDi or Merc CDI, shouldn't have a bad effect to that magnitude.

Good idea. We just have to wait and see.

From what i know (more on theory) diesel with high sulfur will give some negative effects to most modern diesel engine.

All I can say is wait for about 2/3 years and look at the BMW 530d owner's repair/service bill.

No doubt diesels are good, in terms of milage, etc. But are they actually better for the environment cf petrol engines? Someone I know came across a kid whose asthma worsened when he came close to diesel cars. A sign perhaps?

Monkey

From what i heard, BMW 530d (2nd Gen Common-rail Direct Injection with Solenoid Injector) working just fine with our diesel. However i do agree with u that our diesel supply is of a lower quality. We need to improve our diesel quality fast.

Anyone can contribute some extra info on BMW 530d in Malaysia?

no spell checker lah this thing. I cant operate without spell checker!! English SPM 1119 I kenna a C4 balls. Kan Tee Too (translated as "f*ck spider"). Thats why my Inger-land nots sos goods!

I thought of bringing back a diesel car when i eventually come back to malaysia, but ballacks. Diesel in Malaysia ment for lorrys and the likes. Useless for the newer diesel engine cars.

Perhaps there is a conspiracy by the gah-men to not improve the quality of Malaysian diesels so as not to "eat" into Proton's market share, untill they come up with a diesel engine of their own. Hmmmm……pitty isnt it that every decission made by the gah-men always has some hidden agenda attached to it.

yeah i agree….autocar once said, buying that car is more than enough….M5 is not ncecessary to get the same amonunt of power..more specifically torque
