Despite the fact that according to the largest international organization “Our World in Data”, air pollution mortality is decreasing - mainly due to improved indoor air - this type of environmental pollution is one of the world’s leading risk factors. In 2017 approximately 5 million people around the world died from diseases caused by air pollution – strokes, lung cancer, etc. The prevailing part (about 40% of the world’s air pollution) occurs when vehicles are used, mainly personal vehicles, which means that it is necessary to develop measures to improve the environmental friendliness of the use of vehicles. Since the exhaust gases of automobile engines contain a large amount of air pollutants, it is possible to limit their emissions by developing and implementing hybrid vehicles with flywheel energy accumulators. The article considers the dimensionless dependence of the current acceleration of the car to its maximum acceleration in the presence and absence of a flywheel in the system, and checks the reliability of the dependence on the stand.
