An overview of modern technologies for using natural gas as fuel in internal combustion engines
Abstract
The paper analyzes the existing strategies for organizing the workflow of a gas engine in terms of compliance with modern environmental requirements, energy efficiency and power characteristics. The following strategies are considered: operation of a gas engine on poor mixtures, on a stoichiometric mixture, in dual-fuel mode, by injection of natural gas under high pressure. Experimental data are described, the pros and cons of each strategy are identified, and a conclusion is made about the prospects and the need for further research. It was found that the use of various strategies for organizing the working process of a gas engine makes it possible to reduce specific fuel consumption by 5.6%, reduce emissions of toxic substances with exhaust gases by up to 80%. Reduction of fuel costs by 2.3 times compared to diesel engines.
