Development of a bi-fuel power supply system for a diesel engine

Abstract

The relevance of the study is due to the lack of systems in which the proportions of the used fuels in the mixture and the values of the cycle supply are simultaneously controlled depending on the load-speed mode of the diesel engine. The aim of the research is to develop a design for a bi-fuel power supply system for a diesel engine, which allows for the simultaneous regulation of the proportions of the components of a mixture consisting of alternative and diesel fuels, as well as the values of the cyclic supply of this mixture to the diesel cylinders. As a result of the research, an algorithm was calculated for the simultaneous control of the proportions of the components of a mixture consisting of alternative and diesel fuels, as well as the values of the cyclic supply of this mixture to the diesel cylinders. As a result of the operation of the fuel supply system on mixtures of diesel and alternative fuels according to the developed algorithm, it made it possible to achieve the identical operation of a diesel engine on pure diesel fuel at all load-speed modes of diesel operation. Also, in the course of the research carried out, a bi-fuel power supply system for a diesel engine was developed, which makes it possible to simultaneously regulate the amount (cycle supply) and the composition of a mixture consisting of diesel and alternative fuel supplied to the diesel cylinders, depending on the speed and load modes of operation.
