Piston installation component and engine

The utility model discloses a piston installation component and engine, this piston installation component include base and setting element, be provided with the locating hole on the base, the settingelement install in can connect on the cylinder body on the locating hole, still be provided with the through -hole on the base in order to be used for the making piston pass through and get into thecylinder body. In the technical scheme provide by the utility model, the piston ring that will live earlier installs on the piston, packs the piston among the installation component into, through piston installation component pinpointing on engine cylinder block again for through -hole and the accurate cooperation in the cylinder body hole on the engine on the piston installation component, when the piston got into the cylinder body, the cylinder body can be aimed at to the piston, thus piston ring's alive damage has been avoided to the jamming of avoiding piston ring alive to lead to with theinclined contact of cylind
