The purpose of research is to improve fuel economy and reduce the toxicity of internal combustion engines of various types, with various additive systems supply hydrogen gas to the charge air. The object of study: the impact of the additive hydrogen gas in the air charge in the fuel economy, energy and environmental performance of internal combustion engines. Subject of research: fuel efficiency, energy and environmental performance of internal combustion engines of different types of work in different speed and load conditions. Research methods - computational and theoretical and experimental. According to the schedule in 2015 conducted research on the stage: Conducting experimental studies of the effect of hydrogen-containing gas additive in the fuel efficiency and environmental performance of engines. Examination of the engine with the addition of hydrogen-containing process gas into the charge air. The experimental research on the influence of the additive hydrogen gas in the fuel efficiency and environmental performance of the engine revealed: - the addition of a hydrogen-containing gas in the air charge improves fuel efficiency and environmental performance when working in idle; - addition of hydrogen-containing gas in the air charge gasoline engine carburetor and fuel injection system with a feedback system improves fuel efficiency and, as a rule, leads to an improvement in environmental performance of engines operating in idle mode and low loads; - addition of hydrogen-containing gas in a diesel engine air charge slightly improves fuel efficiency of a diesel engine when operating at full load and reduce the opacity of exhaust gas and the concentration of products of incomplete combustion; Research workflow spark ignition engines showed: - the addition of a hydrogen-containing gas in the air charge gasoline engine when operating at low load conditions reduces the unevenness of the successive cycles and intensifies the combustion process. According to the schedule in 2016 conducted research on the stage: Refinement of the mathematical models of the process of the engine and vehicle traffic on the driving cycle. Estimated study the influence of hydrogen gas additives on performance of vehicles and engines. These steps performed: Refined technique and model for calculating the working process of the engine with spark ignition mode operation at light loads gasoline and gasoline with the addition of a hydrogen-containing gas in the airy charge. Changes that take into account: - change of air-fuel ratio by the addition of a hydrogen-containing gas; - changing the molecular weight of gasoline fuel mixture with a hydrogen gas based on the availability of hydrogen gas; - heat changes made with the fuel into the engine cylinder. An increase additives hydrogenous gas of H2/O2 in the range from 0 to 7.88% of the fuel flow indicator allows gradually increase efficiency ?і from 0.237 to 0.27 engine with fuel injection, that is, the engine fuel economy at the maximum additive H2/O2 in this range, resulting in improved workflow, improved by 13.9% excluding hydrogen-containing gas to costs. Refinement of the mathematical model of car traffic on the driving cycle, which takes into account features of a mathematical model of the motor with the addition of a hydrogen-containing gas in the air charge. Using the results of the experiment conducted computational studies of the effect of hydrogen-containing gas additives on the performance of cars with different types of engines in motion by the European driving cycle mode. Determine whether the value addition of hydrogen-containing gas.5481
