Selection of Gas Injector Units for Converting Diesel Engines to Gas

Abstract

Given the rising cost of crude oil and fuels based on it, as well as acute environmental problems, alternative energy sources are becoming increasingly important. Natural gas is the most affordable alternative fuel for Russia. A study was carried out at FSUE NAMI on the conversion of the L6 engine from diesel to natural gas. The study included testing of gas fuel equipment both to determine its performance and to test its stability at low temperatures. The greatest interest was the selection of gas injectors for distributed gas supply to ensure the required cycle flow rate. Motorless tests of electronic gas injectors BOSCH, IMPCO, WOODWARD, as well as gas injectors produced by Concern KEMZ JSC were carried out. Based on the results obtained, the choice of gas injectors for further use in the gas engine was justified.
