In a common rail diesel engine, main injection is executed as injection divided into first divided main injection and second divided main injection. In the first divided main injection, fuel injection is stopped before a fuel evaporation speed in a combust...

The method involves creating a thermo-dynamic motor simulation model under consideration of an energy balance, mass balance and gas state equation in a cylinder of an internal combustion engine and in an inlet and outlet system. A controlling and/or adjust...

An internal combustion engine (1) generates power by burning a mixture of fuel and air in a combustion chamber (3). The internal combustion engine (1) is provided with a crank angle sensor (14), an in-cylinder pressure sensor (15) detecting an in-cylinder ...

To estimate the fuel/air ratio used by an internal combustion motor, with exhaust gas recirculation, the richness of the fuel mixture in a cylinder is estimated to give the total oxygen drawn into the motor. The oxygen content of the exhaust gas, oxygen in...

An internal combustion engine (1) causes an air-fuel mixture produced in a combustion chamber (23) to burn by means of ignition using a spark plug (24). A programmable controller (20) calculates a reaction probability expressing the combustibility of the a...

A fuel injector (6) and spark plug (7) are arranged in a combustion chamber (5) of an internal combustion engine. By forming by stratification a self-ignitable preliminary air-fuel mixture in the combustion chamber (5), a spatial distribution is given to t...

The method involves specifying the fuel quantity to be injected for a desired engine power, determining a sub-quantity per individual injection process and selecting injection parameters for this and the desired power.
