As to the engines on vehicles or tractors etc, it is hard to evaluate the combustion process of each cylinder according to the indicator diagram measured with the indicator simultaneously.
Through measuring the indicator diagram of the combustion process and with the help of an analysis model, factors affecting engine performance are isolated in order to better performance.
A new model was brought forward to calculate the heat release rate curves of a diesel LPG dual fuel engine on the basis of indicator diagrams measured by a combustion analyzer.
