Abstract

The problem of deteriorating environmental situation in megacities, including due to the toxicity of exhaust gases of transport engines, requires a comprehensive solution. The use of hydrogen for the internal combustion engine is primarily determined by environmental purity, in limited and renewable raw materials, as well as unique motor qualities, which opens up the possibility of its wide-ranging use in modern engines without significant design changes. A lot of development has been done in this area with several experiments on gasoline as well as diesel internal combustion engines so far using HHO gas or brown gas as a fuel efficiency enhancer. This paper examines the methods of using hydrogen internal combustion engines as a qualified fuel.
