The purpose of the SRW is to develop ways to improve fuel efficiency and environmental performance of vehicle engines by improving systems of supply and regulation and rational use of alternative fuels. Methods of research - calculation-theoretical and experimental. The first section. The analysis of literary sources on the application of alternative types of fuels in the ICE is carried out. Experimental studies on the addition of an inert additive CO2 to gas fuel have been carried out. Experimental studies on the addition of water-hydrogen gas to the fuel-air mixture of the gasoline engine have been carried out. With the help of polynomial models, the gasoline engine, when added to the hydrogen-containing gas, is described as a consumer of fuel and air and a source of emissions of harmful substances. The second section. The influence of the method of disconnection of the cylinder group (transition from standard throttling to the combined method) on the fuel efficiency of the gasoline engine and vehicles in service is investigated. The third section. Experimental studies were conducted to determine the influence of air temperature on fuel economy and emission of harmful substances in the EG of a carburettor with spark ignition of the MEMZ-245 of the ZAZ-1102 vehicle during its warm-up in road conditions. The efficiency of the catalytic converter's heating after the cold engine start has been evaluated. Modeling of heat losses of automobile gasoline engine in operating conditions was carried out. An estimation of efficiency of thermoelectric utilization of thermal energy of ICE is carried out. The fourth section. The results of investigations of electronic Hainzmann speed regulators for different settings of the PID control algorithm are carried out, calculations are made on the mathematical model of the intrinsic electronic speed controller with PID-regulation, the further use of this type of regulator is substantiated. The fifth section. The logical-probabilistic diagnostic model of the diesel engine is developed, which allows to determine the minimum number of non-objective and sufficient diagnostic parameters and to constru Product Description popup.authors popup.nrat_date 2020-04-02 Close
