Computational Modeling of the Liquid LPG Injection into the Suction Manifold of an SI Vehicle Engine

Abstract:

LPG is a very first-rate alternative fuel for a vehicle SI engine. By mixture formation using the injection of the gaseous LPG into suction manifold of the naturally aspirated SI engine the engine power is reduced to the original petrol engine power. This advantage is corrected by mixture formation using the liquid LPG injection into the intake air to the suction manifold. The paper deals with the computational modelling of the process on the liquid LPG injection, especially of the history LPG pressure and the LPG temperature before outlet nozzle. The calibration of the computational model has been performed by the experiment. The paper proposes the design precaution on the icing of the outside on the outlet nozzle.
