摘要：
The results of the work on the development of a new composite alloy pistons designed for internal combustion engines are presented in the article. Tests of alloy crystallization, metallographic tests, tensile strength and hardness tests, coefficient of thermal expansion and tests for seizure resistance as well as the engine tests were performed. Tests of dimensional stability of the pistons in the thermal chamber was carried out and found that permanent deformations of the piston diameter do not exceed 2 mu m. The engine with new pistons showed a lower consumption of lubricating oil, lower levels of exhaust emissions and lower noise levels in comparison to the standard engine.
