Over at the 37th Vienna Motor Symposium, Volkswagen is introducing the EA211 TSI evo engine, with the first model being a 1.5 litre TSI with two outputs – 128 hp and 147 hp – to be launched later this year. The new TSI engine generation is claimed to be more efficient, more powerful and with reduced emissions.
The EA211 TSI evo engine has a new combustion process that allows for maximum torque from 1,300 rpm. Meanwhile, the new technology elements enhance efficiency by up to 10% compared to the existing 1.4 litre TSI unit. Furthermore, consumption is said to be reduced by up to one litre per 100 km.
New to the engine is a Miller combustion cycle with a high compression ratio of 12.5:1. A key feature in the EA211 TSI evo, the result sees improvements in thermodynamic efficiency that’s implemented systematically through four main development targets.
A new exhaust gas turbocharger with electrically actuated variable turbine geometry (VTG) is also present. The new turbo allows for “very high” turbine output and high charge pressure from low engine speeds thanks to the new combustion cycle.
The increased accumulation effect on the VTG turbine, in combination with a reduced moment of inertia in the turbocharger, results in very spontaneous response characteristics. Compared with a 1.4 litre TSI unit, the step change load to the maximum torque takes place about 35% faster.
As for the cylinder head, it has been re-engineered through optimisation of the water jacket for improved heat dissipation and adaptation of the valve angle and combustion chamber for the best possible execution of the Miller combustion process.
For efficient thermal management, there’s a new map-controlled cooling module, which ensures the water in the crankcase and the engine, as a whole, remains stationary during the warm-up phase, among other benefits. The rapid engine warming improves heating in the car’s interior and reduces engine friction during the warm-up process.
Cylinder liners in the aluminium crankcase for the 147 hp unit are coated using atmospheric plasma spray (APS) process. Fine-grain spray powders combined with a specifically optimised grinding process allows for tiny lubrication pockets, which ensures low friction and wear as the piston rings glide.
Apart from that, it provides better heat dissipation, which results in improved anti-knock properties during combustion and improved corrosion resistance when required to run on poor-quality fuels. The APS technology also exhibits good wear resistance in hybrid applications.
The common-rail injection system is also a key feature. Optimisation of the overall system and its components gives an increase in injection pressure up to 350 bar. This leads to benefits such as substantial reduction in particulate emissions.
Elsewhere, the indirect charge-air cooling has been modified. With a new installation position, the size has been increased and as an outcome, the performance of the cooler is better too. With that, it’s now able to reduce the temperature of the charge air to 15 Kelvin above that of the ambient air.
The injector tip’s diameter has been reduced to 6 mm, beneficial for integration into the combustion chamber. It also improves stiffness and reduces temperatures at the injector plate. Other features include an extensive friction package, which comprises of a map-controlled, fully variable oil pump, polymer coating of the first main crankshaft bearing and a switch to low viscosity 0W20 oil.

Still cannot solve last gen TSI engine problem, now debut new TSI engine. I love you VW.
Tsi is rock solid as an engine.. Its the dsg thats bringing the house down….
Good design also useless. If use substandard parts in production. Else won’t be so many TSI pistons fried.
Isolated pistons issues in turbo cars is nothing new across all makes. If you are old enough to remember those Nissan RB turbo engines and Toyota 1JZ, 2JZ turbo engines have similar burnt piston issues just like current new turbo engines from VW, Nissan BMW,…etc. The only difference is that VW owners and critics are more vocal about their issues (sometimes perceived) since the 2014 picket incident.
Dsg is much sucker
Be real. So is Honda critics next? With Civic turbo
Cut-cost on parts material is suicidal. That’s how VW buried themselves. Not really the design.
Some gasoline-heads modded their VW to 220-280/300hp from the tiny 1.4(Twin) with forged pistons and later version of LUK clutch pack. Be it dry or wet no big deal.
So go fook VGM for mishandling
Solid engine ? I own 1 , golf TSi
got Misfire, change 1 engine claim from VW.
not a solid engine as I owned it just over a year,
mileage around 40k km when it happen.
All being serviced at VW sc on time.
anyone having same issues ?
Has it occurred to your uneducated mind that new engines are usually the solution to older engines, because the inefficiencies and bugs will be worked out of the new designs?
no more tipu tipu data…
“With reduced emissions”
Another DieselGate Scandal~

“With reduced emissions”
Another DieselGate Scandal~
———————————————————-
Aiyoo, dont know what u type ke???the name is “Dieselgate scandal” , its about the diesel’s engine scandal….
this is TSI, petrol engine…yeap, so far no “petrolgate scandal”
Still using DSG gearbox? TSI engine is not the problem, dum dum!
still using DSG gearbox? TSI engine is not the problem. The gearbox is!
Every 1 trashing here talks like they are an automobile engineer.. come on guys.. its not even launch yet.. don’t make a fool out of yourself please.. you guys are pathetic!!
Junk engine. 1nzfe is much better, can do 350Nm
Kuahkuahkuahkuah.. 1nzfe? Yes better if fix it on Yamaha 125.
welcome to paultan.org!
Clearly a newbie. You never read kah such comment ? Car wrapped up with newspaper. After lunch if tak laku then can close shop
Can see Pinochio’s nose getting longer & longer
Malaysian only remembered DSG cause problem and never stop criticism
Don’t trust this Co. nor “nasi-goreng-ridsect”.
Very Worrying
kinda sceptical now… VW might be hiding something here
high compression ratio + turbo = higher chance piston crack
Lets take the wait and see approach…vw likes the consumer do the testing…as seen in the past…
I rather put my money on this dieselgate engine than underpower Toyota one.
If VW so problematic how come able to ditch reliable Toyota to 2nd spot in sales? Grow up la,bolehland market alone can’t spoil the worldwide contribution.
In Msia ppl are talking abt VW unreliable dsg…tsi…america & europe dieselgate scandals…etc..etc..
BUT the scary part is that in reality, they VW group is overtaking Toyota as world No.1 currently! seriously weird stuffs
Those cars sold are not using DSG or not in hot countries
few 1.4 tsi had their engines changed under warranty, some more than once..what happens when warranty expires?..masuk sr20?..
And how many SR20 engine owners had to have the engines replaced during its hey days? I remember having to change 2 SR20 engines in 3 years during my younger days.
