Air Brake Compressor Repair Kits Pistion for Hino Compressor Piston P11C Engines Parts 29191-1220
High-power diesel engines work in difficult conditions. Maximum pressure in the combustion chamber can reach 20 MPa and maximum temperature of some piston surfaces can exceed 450 °C. It is possible to improve piston cooling by creating special cooling cavity. Injector supplies this cooling cavity «A» with oil through oil supply channel «B». For better temperature reduction construction should be carefully calculated and analyzed. Oil flow in the cooling cavity should be not less than 80% of the oil flow through the injector.
A – cooling cavity; B – oil supply channel
The pin itself is of hardened steel and is fixed in the piston, but free to move in the connecting rod. A few designs use a 'fully floating' design that is loose in both components. All pins must be prevented from moving sideways and the ends of the pin digging into the cylinder wall, usually by circlips.

Pistons are usually cast or forged from aluminium alloys. For better strength and fatigue life, some racing pistons[1] may be forged instead. Billet pistons are also used in racing engines because they do not rely on the size and architecture of available forgings, allowing for last-minute design changes. Although not commonly visible to the naked eye, pistons themselves are designed with a certain level of ovality and profile taper, meaning they are not perfectly round, and their diameter is larger near the bottom of the skirt than at the crown.[2]
Early pistons were of cast iron, but there were obvious benefits for engine balancing if a lighter alloy could be used. To produce pistons that could survive engine combustion temperatures, it was necessary to develop new alloys such as Y alloy and Hiduminium, specifically for use as pistons.
