MEASURES TO EXPAND THE USE OF GAS FUELS IN TECHNOLOGICAL VEHICLES

Abstract

The aim of the work is to develop measures to ensure the possibility of efficient operation of wheeled tractors and other technological vehicles using gas fuels. The D-243 diesel engine was converted into a spark ignition gas engine and bench tests were carried out, which confirmed its operability and showed good performance. The power of the gas engine is at the level of a diesel engine, the total toxicity of exhaust gases is 1.8 times lower compared to a diesel engine, but fuel consumption is higher for a gas engine. The MTZ-80 tractor was converted to run on gas fuels using the same technology and elements. Its road tests were carried out, which showed that there are certain peculiarities in the control of the gas engine and transmission of this tractor. To ensure the efficient operation of technological vehicles running on gas fuels, it is proposed to: install a high-energy ignition system; develop a system for preheating the gas reducer; develop methods for providing technological vehicles with gas fuel.
