It sounds like just what everyone wants: all of the power and efficiency of a diesel engine mated to the low tailpipe emissions and lower production cost of a small gasoline engine. Several iterations of this engine are being worked on around the world, but the latest is the DiesOtto from Mercedes-Benz.
Mercedes showed the engine at the International Motor Show in Frankfurt in September 2007 and astounded everyone. The engine, which was showcased in the F700 concept car, combined hybrid technology with this version of a future internal combustion engine. The performance numbers were very impressive for a full-size luxury car: only 5.3 liters of gasoline per 100 kilometers (or 44.38 mpg) while still delivering acceptable acceleration.
Mercedes says this 4-cylinder engine is not far off in the future since its direct injection components are already in use in its current 3.5-liter gasoline engine. In the DiesOtto version, the engine has two-stage turbocharging so the 1.8-liter engine provides the same level of performance as the current 3.5-liter gasoline V-6 engine or the 3.0-liter turbodiesel V-6 engine currently offered in the S-Class.
The biggest change from current gasoline engines is the use of homogeneous charge combustion ignition (HCCI), which mimics the combustion process used in diesel engines. The small engine produces 238 hp from its DiesOtto engine (and a massive 400 Newton-meters or 295 lb.-ft. of torque). Mercedes says it will propel the large car to 62 mph in 7.5 seconds while still delivering 127 g/km of CO2 and meeting proposed EU 6 emissions regulations....
