Effect of the proportion of natural gas in the feeding dose on the combustion process in a self-ignition engine with a Common Rail fuel system

Abstract

Limited oil resources, combined with the need to stem the toxic emissions to the atmosphere, necessitate seeking alternative fuels for combustion engines. According to forecasts, natural gas will be one of those fuels whose importance is likely to increase in future. Because of its properties, natural gas can be used directly in spark-ignition engines. When natural gas is used as fuel in much more efficient self-ignition engines, it is necessary to use dual fuelling. This paper presents the effect of the proportion of natural gas in the feed dose on the course of the combustion process in a turbocharged self-ignition engine. The engine was controlled by the Common Rail fuel system, programmed for single-fuel operation.

“…The green cluster, with 29 keywords, refers to the study of engines, energy consumption, new sustainable types of fuel [55], new types of combustion systems [56,57], biodiesel [58], natural gas [59], and liquefied petroleum gas [60]. Many articles presented research focused on internal combustion engines, which is a heat engine in which the combustion of a fuel with an oxidant takes place in a combustion chamber that is an integral part of the working fluid flow circuit.…”
