Mahle - 200 hp 3 cylinder engine

[Mr Robert]

German subcontractor Mahle has, once again, showcased its super efficient 3 cylinder engines.

The numbers are very promising.

1.2 litres, 200 hp and 287 Nm @ 2,500 rpm. The consumption has not been officially measured but gains between 30 and 40 %, compared to a NA 2.4 litre V6, has been accomplished.

B.t.w., does not BMW hold a stake in Mahle?

 

[Kowalski]

Amazing power output for such a tiny engine.

No. Hahle GmbH is owned by non-profit Mahle Fundation.

But there was a joint-venture project with BMW (crankshaft) in the past but that company is now 100% owned by Mahle (BMW dropped out).

Those are some amazing numbers.


Waiting for some morons on the net to claim: "It's still a 3-cylinder!"

You DO know your shit...

Mahle is the compagny building the new Macca engine isn't ?

 

[Mr Robert]

My only concern is lag. Small engines and big hp often mean high pressure turbos, which in turn often mean big lag. That is the main thing to work around.

Hence the sequential twin-turbo layout for the big numbers version.

Yes, that is an absolute must. I guess this could be calculatad, but I get a feeling that it would almost take more than two turbos to close the gap in atmospheric pressures... or two really good ones.

Electric supercharging. It has to be the next thing. Instead of using exhaust gas to spin a turbine from low rpm or a crankshaft driven compressor, an electric motor could be used to spin a compressor wheel during low throttle loads. This would eliminate initial lag and once volumetric flow is sufficient, a second turbocharger could take over the high-power duties.

 

[Poverty]

very very impressed.

I thought audi owned mahle.

I know for sure though that mahle used to supply the forged pistons in audis turboed lumps.

 

[Mr Robert]

I think I can imagine it, the way it would work, that is, but the problem that spring to mind is; how to power the electric turbo? Granted that this will not be set up in a hybrid, because then I think the electric power supply will not be an issue.

What you will get, however, is that lovely "Turbo" meter featured in almost every 80's racing game, indicating how much turbo you have left before it will have to be recharged

Mahle is a big player in the supplying business towards the automotive industry.

Another clever thing they can do with electric assisted turbo is that the waste gate will be eliminated. The boost pressure will be controlled by the electric motor, which will switch to the generator mode to apply load on the turbo shaft once electric assistance is not required. The only problem they have is the massive amount of current required to spin the turbo at high rpm.

 

[martinbo]

Yeah, quite right. How fast can an electric motor spin? Surely not as quickly as the 100 000+ rpm of a small turbo?

That's why I prefer to refer to the concept of electrically powered supercharging because exhaust gases won't play in part in turning such a compressor. What I'm describing is essentially a centrifugal supercharger (with the impeller side similar to that of a turbocharger) but instead of being driven by a belt off the crank, the impeller is actuated by an electric motor.

Martin your on the ball my fellow countrymen! Electronic turbocharging is techno being researched by Perkins in the U.K. for the next generation TIER 6 engines for use in the industrial applications also.
