EVALUATION OF THE INFLUENCE OF DIESEL TO GAS-DIESEL ENGINE CONVERSION ON THE PARAMETERS OF ITS WORK CYCLE AND CHARGING SYSTEM
Abstract
Simple and fast models of the working process of internal combustion engines make it possible to speed up and reduce the cost of their development. Models can also be used to load into the memory of the electronic control unit of the engine in order to optimally control all its adjustment parameters in a wide range of operating modes. The Moscow Automobile and Road Construction State Technical University (MADI) proposed a gas diesel working process model based on a previously developed one-zone diesel working process model. The assessment of the main differences between the algorithms for calculating the compression-combustion-expansion processes in diesel and gas diesel engines and their influence on the performance of gas diesel engine is carried out. To calibrate the model, calculations using the FIRE model from AVL and the results of experimental tests of a gas diesel engine were used. A high convergence of calculated and experimental results is shown.
