Method of Improving Performance of Automobile Gas EngineA Technique for Improving the Performance of a Gas Engine

This article is necessitated by the need to improve indicators of fuel efficiency and exhaust gas toxicity for internal combustion engines working on alternative fuels. It is noted that natural gas is one of the most promising alternative fuels, and its advantages as a motor fuel are described. Problems occurring when adapting internal combustion engines for operation on natural gas are analysed. Indicators of fuel efficiency and exhaust gas toxicity of a gas engine of the KamAZ family are studied. It is shown that to achieve the best operational indicators of the gas engine under consideration, it is advisable to ensure its operation in full load modes. This improvement of the fuel efficiency and exhaust gas toxicity can be achieved by deactivating some cylinders and operating the other cylinders in the full load mode. Nitrogen oxides emission should be reduced simultaneously with the application of the cylinder deactivation technique.
