Modelling the Injection of Spark-Ignition Fuel into Combustion Chamber in the Gas and Diesel Operating Process

Abstract

This article studies the questions of reducing the consumption of diesel fuel via the gas and diesel operating process in small-sized internal combustions engines as well as lowering the amount of noxious substances in exhaust gases. Internal combustion engines (ICE) are the main consumers of petroleum product fuels, the reserves of which are significantly limited in some regions of the world. One of the most promising ways of decreasing the consumption of diesel fuel, diminishing the harmful emissions while reaching the goal of increasing the engine life and using the gas seems transforming diesel engines into gas ones. The most popular method of modifying the diesel engine is the introduction of the gas and diesel operating process, i.e. replacing some part of liquid fuel with gas, most often compressed natural gas. The injection of fuel into the cylinder has been modelled. This simulation has been run with the help of a specially made experimental facility which is based on the diesel 2CH,5/11.
