To improve the power and fuel and economic performance of a gasoline internal combustion engine, it has been proposed to improve the insulating properties of the piston by forming a heat-insulating coating on the working surfaces of the piston head with a thickness of 25...30 μm using the microarc oxidation method. Comparative results of engine tests are carried out, which showed that an engine equipped with pistons with a heat-insulating coating on the working surfaces of the head increases
