A MODEL TO PREDICT COMBUSTION NOISE AND IGNITION DELAY IN DIESEL ENGINES
A diesel combustion model is described which is intended to find minimum combustion noise level from a generalised relationship for ignition delay and tape-recorded data obtained at carefully chosen engine operating conditions for specific engines. This model will usefully predict the peak rate of heat release and the overall level of combustion noise for a wide variety of rate of injection diagrams. The agreement between the predictions from the model and results from engines is most encouraging. So far the most interesting result is that it is possible to approach minimum combustion noise level for indirect injection engines with a variety of injection rate diagrams without incurring unacceptable penalties in power or fuel consumption.
