T417728 Piston Assembly for C4.4 and 1104D-E44T Diesel Engines
The T417728 piston assembly is suitable for CAT C4.4 and Perkins 1104D-E44T diesel engines. It is a key moving component in the engine's combustion system, responsible for converting combustion pressure into crankshaft output power. This piston assembly is made of high-strength aluminum alloy and undergoes precision machining and heat treatment processes, possessing excellent high-temperature resistance and fatigue resistance, enabling stable operation under high-load conditions. It is suitable for applications such as construction machinery, industrial power, and power generation equipment.
The piston features high overall strength and strong resistance to thermal deformation, effectively withstanding the high-temperature and high-pressure combustion environment of diesel engines. Combined with a precision-machined piston skirt design, it ensures smooth operation and reduces friction and noise.
