Abstract
This paper describes a simulation model of a naturally aspirated four stroke diesel engine with a swirl prechamber. The study was carried out use a "two-zone" thermodynamic in both chambers model as regards the closed valves phase and "filling-emptying" one as regards the open valves phase. The capability of the previously described model to predict the pressure cycle as well as polluting emissions of a I.D.I. engine was verified by comparing experimental and evaluated data. Comparison between the result yielded by the model and experimentals ones shown the model good predictive capability as regards indicated pressure cycle nitric oxide and soot productions.
