Fuel efficient low pollutant diesel engine
The main parameters influencing mixture formation in a diesel engine have been ascertained. The verification of these essential findings on the single-cylinder test engine show that there are additional possibilities for reducing fuel consumption and the gaseous and solid pollutant content by a time-saving optimisation of the combustion processes. Besides the interaction of the droplets in the fuel jet, the interaction between jet and combustion chamber wall has a major influence on the heterogeneous mixture formation and thus also on emission and fuel consumption. To reduce NO-emissions, injection should be extremely retarded. If this measure is not to have a negative effect on particulate emission and efficiency, mixture formation should be accelerated. It is shown that this can be achieved by better utilising the interaction of the droplets in the jet and/or the interaction between fuel jet and combustion chamber wall.
