Simulating combustion process of LPG in separate chamber of dual fuel engine
Abstract
The reduced pollution level of diesel engine by replacing a part of diesel fuel with LPG fuel. This paper focused on simulation effects of alternative concentration of LPG fuel to the engine’s performance and the level of pollution. Calculation is studied on the original diesel engine with separate combustion chamber. Due to the anti-detonation of LPG lower than that of diesel fuel so compression ratio of the engine need to be adjusted reasonably to avoid the detonation occurred. The maintenance of the compression ratio of the original engine can be done by mix of LPG-air with CO2.
Below is some clips show calculated evolution results of O2, C3H8, temperature, rate of fluid in the combustion chamber:
