Innovative engine technology for milage
(Please, let's keep this thread to additions and/or relevant discussion. thx.)
Smaller+more power+ fuel efficiency topics only. High compression, low-knock: Design To Improve Turbulence In Combustion Chambers "Results from a dynamometer test by the Automotive Research Association of India (ARAI) showed a reduction of 42.5% in BSFC / fuel consumption when fully loaded, producing more torque and power at lower temperatures." Opposing-piston radial design?: Angel Labs :: Home "With 40 times higher power to weight ratio, low parts count, low maintenance, high mechanical efficienty, and low pollution, the MYT™ Engine will benefit airplane, big ship, 18 wheeler, SUV, passenger car, even down to carry on power generator applications." 200hp, 3 cylinder, 1.2L: MAHLE.COM | Put to the test: the MAHLE downsizing engine "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." Integrted hybrid and supercharger: SuperGen "SuperGen is an electro-mechanical boosting system which provides exceptional response even at low speed on heavily downsized engines. The system replaces the alternator and can also provide mild hybrid functions." More links: Engine Technologies Fuel economy in automobiles - Wikipedia, the free encyclopedia |

HA! I love your first link there. ...they go for sounding all techy and .. ."This form of combustion further achieves higher thermal efficiencies that deliver better Break Specific Fuel Consumption (BSFC)"
Is that where an engine falls apart with less fuel?  btw, Improving turbulence in combustion chambers is nothing new. Engineers have some great tools for optimizing this mixing. ...toroidal swirl usually gives the best mixing. ...although, "Vortex" may sound more powerful. The thing is, so much of the time, motors are built for great BSFC . . .but they then lack flexibility. That is, they are tuned to work well in an rpm sweet-spot. Maybe if we had a great CVT, ... anyway. so much of this has been done before. It's hard, for most, to sort out what's a scam, and what's actually useful. Although, kudos to Porsche for their inroads into in-cylinder injection (gasoline engines) ...gain an MPG or two there.
