WebWhat is piston cooling? Cooling channels—The piston is cooled by oil flowing through a cooling channel or gallery incorporated into the piston. One or more oil spray nozzles feed oil into the cooling channel through inlet openings in the bottom of the piston. The cooling oil exits the cooling channel through one or more drain holes. WebThe super-hot pistons are moved out of the press and air cooled for about an hour. After cooling, the pistons are once again placed in an oven, this time to strengthen them. Next, the pistons are transferred to a lower temperature oven. The low heat serves to stabilize them. The pistons are then taken into a lathe machine and excess parts removed.
