Improving the energy and environmental performance of a diesel internal combustion engine by using a hydrogen-containing additive

BACKGROUND: The areas of hydrogen energetics development are analyzed. The main problems faced by Western automakers and which determine the ways to solve the problems of hydrogen vehicles are outlined. It is noted that small-scale production of hydrogen cars has already begun in Europe and the USA. The development of this direction requires the creation of a network of filling stations, which is related to the high financial cost of hydrogen fuel production technologies and the development of the appropriate infrastructure. The world economy transition to a new energy source requires the introduction of large electrical capacities.

AIMS: Technologies of vehicle onboard hydrogen production with use of hydrogen-containing substances are of interest of the study, as they are highly safe, cheap in production and easy in service.

METHODS: The experimental design developments on converting diesel and gasoline internal combustion engines to run on hydrogen, made by NAMI in the past years, are considered. In the development of this direction, MADI has developed an original method for vehicle onboard hydrogen production with hydrogen supply to the cylinders of a bifuel diesel internal combustion engine.

RESULTS: During the tests, an increase in power indicators, an increase in the effective efficiency of the internal combustion engine and a decrease in the content of CH and CO in the exhaust gases of a diesel engine with a certain increase in nitrogen oxides were obtained.
