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.
