China Daewoo Excavator Engine Piston Liner Ring D1146 D2366 DE12 | Tonkee®

Daewoo Excavator Engine, Piston Liner Ring D1146 D2366 DE12 | Tonkee®

Piston: The piston for the D1146 engine is designed with high-quality materials to withstand the rigors of heavy-duty applications.


It typically features a cast aluminum alloy construction to provide strength and durability. The piston has a specific bore size and stroke length, ensuring proper combustion and power generation within the engine.

Liner: The liner, or cylinder sleeve, is responsible for maintaining a precise fit between the piston and the cylinder. It prevents excessive wear and ensures efficient sealing. Daewoo liners for the D1146 engine are made from materials such as cast iron or steel with chrome plating to enhance their durability and resistance to friction and heat.

Ring: Piston rings are essential for sealing the combustion chamber and preventing the leakage of gases. They are typically made of high-strength alloy materials that can withstand the high temperatures and pressures inside the engine. The ring set for the D1146 engine includes compression rings and oil control rings to maintain proper lubrication and prevent excessive oil consumption.
