DiesOtto

Looks like those zainy germans have been hard at work advancing the humble (and vastly superior) petrol engine.

July 25, 2007 Don’t count out the petrol engine just yet according to motoring giant Mercedes-Benz, which has unveiled a new gasoline engine offering the high torque and fuel economy of a diesel together with extremely clean emissions. The company is highly optimistic, calling it “the future of the gasoline engine.” The Mercedes-Benz DiesOtto powertrain is a further development of the spark-ignition engine and includes features such as direct gasoline injection, turbocharging, variable valve timing and variable compression and it will be used in conjunction with a hybrid integrated starter/generator module. At its core lies the controlled auto ignition, a highly efficient combustion process similar to that of a diesel. The result is an 1800cc four-cylinder motor producing 238 bhp (175 kW) with torque of 400 nm while delivering 6 l/100 km (47 UK mpg, 40 US mpg) in an S-class.

Toyota are already working on a system better than i-Vtec and VVTL-i. They bought the rights to rotory valve technology. They were almost about to use it in their 3L V10 F1 engine, but the engine rules changed during development and Reanult moved to ban them from using it in their V8 engine. Or so I hear....
