Piston assembling method involves connecting first baffle plate between inner and outer annular walls, such that inner surfaces of inner and outer annular wall define closed cooling gallery

摘要

The method involves connecting a first baffle plate (48) between an inner annular wall and an outer annular wall, such that inner surfaces of the inner and outer annular wall define a closed cooling gallery. A stand pipe (56) is extended axially towards a bowl portion and secured between the end portions of the two baffle plates. Independent claims are also for the following: (a) a piston; (b) and an internal combustion engine.
