Detailed Product Description

Doosan Engine Parts Diesel Fuel Pump For Doosan Piston Engine

Diesel Fuel Pump For Doosan Piston Engine For Sale

Piston type and surface treatment : Alfin Reinforcement

Created for operation in high temperature environment like turbo engines.

Moly Skirt : Help produce less frictional heat and engine noise.

.

Nitriding: The nitriding products have excellent wear resistance, fatigue resistance, corrosion resistance and high temperature resistance .

In order to reduce the intense heating of the first ring groove by the gas, the piston of the diesel engine is usually equipped with a spiral shallow groove around the fire bank to reduce the gas channeling along the gap between the piston and the cylinder liner by using the labyrinth step-down principle.

Top of piston

The thickness of the piston generally tends to decrease. It is mainly restricted by the two contradictory factors of the combustion pressure and the reduction of the temperature gradient. The thickness is too thin, the ability to bear mechanical load is poor, will cause mechanical deformation; If the thickness is too thick, the temperature gradient is too large, causing too much thermal stress and thermal deformation. Therefore, the piston head thickness varies with the maximum combustion pressure of the engine, the cylinder diameter, whether there is oil cooling, and thecombustion chamber form
