Digital Calculation and Research of Combustion Heat Release Rate for Divided Chamber Diesel Engines

As far as the theoretical model and calculation method of combustion heat release rate for the swirl chamber diesel engines is concerned, the equivalent thermodynamic system calculation model under varying operating mode is proposed and established on the basis of that under constant operating mode(rated mode)and the problem of calculating transient flow coefficient at the connecting passage between the main and auxiliary combustion chambers under varying operating mode is resolved desirably by using equivalent thermodynamic system method as well This method is of common importance for the divided chamber diesel engines and integrated software package for calculating combustion heat release rate and flow coefficient of the divided chamber diesel engines is developed correspondingly
