Dynamic Aspects of the Diesel Engine Work 2007-01-4210
The results of indicating the Diesel engine in dynamic conditions have been presented in the paper. Dynamic conditions of engine work were achieved by free running up of the engine caused by the step change of the position of the lever controlling the fuel dose. The parameters of the combustion process were calculated: mean indicated pressure, maximum combustion pressure, the angle of combustion start occurrence, the angle of maximum combustion pressure occurrence, maximum velocity of pressure rise, the angle of self-ignition lag. The influence of the angle of dynamic fuel pumping start and injector opening pressure on the values of mean indicated pressures obtained in dynamic conditions were the subject of analysis. The method of neural network was used for the purpose of investigation. The results may be useful to effective control of the diesel engine under dynamic conditions. The method of neural networks enables easy application of the obtained model to the problem of diesel engine control. The obtained test results widen general knowledge about diesel engine operation in dynamic conditions.
