Abstract
The invention provides a piston, an engine and a piston manufacturing method. The piston comprises an aluminum piston body and further comprises an insert made of high-nickel cast iron and embedded into the piston body. The insert comprises a piston top face insert body and a first ring groove insert body. The piston top face insert body is embedded into the top end of the piston body and extends to the opening edge of a combustion chamber. The first ring groove insert body is embedded into a first ring groove of the piston body. Due to the fact that the thermal expansion coefficient of the high-nickel cast iron material is very close to that of a cast aluminum alloy material, the insert can be well bonded to the piston body under the working temperature of the piston, and it is guaranteed that the insert and the piston are integrated. The high-nickel cast iron material is high in strength, and the strength of the high-nickel cast iron material is not affected under the working temperature below 500 DEG C, so that the heat resistance of the top of the piston can be improved through the insert made of the high-nickel cast iron material; and the size of the insert is small, and the weight of the piston is increased a little, so that energy consumption of the engine is not increased remarkably, and the requirements for the high fire blast and high-power density of the engine piston are met.
