An Examination of Some of the Errors Normally Associated with the Calculation of Apparent Rates of Combustion Heat Release in Engines 710135

The rate of heat release analysis of combustion processes in a diesel engine, derived from a knowledge of cylinder pressure time records, has now developed to be an effective tool for considering and evaluating the progress of these processes for research and development purposes. This paper examines some of the main errors and assumptions normally associated with the calculation of apparent rates of combustion heat release in engines, and suggests ways to improve the accuracy of these calculations.
