D1146 Engine Piston

Construction Machinery Parts Engine Piston D1146 For Doosan Daewoo

 

In recent years, due to the continuous improvement of engine enhancement, the engine speed, average effective pressure and piston average speed have been greatly improved compared with before, so the thermal load and mechanical load of the engine have increased. Since the piston plays an important role in the engine, the design and manufacture have also been greatly changed and improved, so as to meet the high emission standards in the real society.

 

I. piston height

 

The height of the piston is gradually shortening, the diameter of the piston has been greater than the height of the piston; The compression height is also getting shorter. These changes in the piston shorten the height of the engine body and the whole machine, improve the rigidity of the engine body and the whole machine, reduce the engine volume, weight, metal consumption and cost, and reduce the reciprocating mass, inertia force and main bearing load. In addition, the height of the piston shortened, the weight of the piston set can be reduced. The total weight of each piston group of the engine generally accounts for 1.2~3.0% of the total weight of the engine.

 

Number of piston rings

 

In recent years, in order to reduce the friction work, improve the mechanical efficiency, reduce the ring height and shorten the piston compression height and total height, the number of piston rings is decreasing. From the 30 s 5~6 ring groove development to 2~3 ring groove. It was found that more than one compression ring was not necessary, because if the upper compression ring failed, the other compression rings could not seal the gas in the combustion chamber from leaking into the crankcase, nor could they control the oil up the cylinder wall into the combustion chamber. Therefore, instead of increasing the number of piston rings, it is better to take measures to improve the performance of piston rings, with a compression ring and two oil ring grooves to ensure the completion of sealing gas and oil control.

Piston type & surface treatment

 

Alfin Reinforcement

 

Piston with alfin reinforcement are resistant to compression ring groove wear . the alfin reinforcement also act as a heat barrier minimizing heat conduction from piston skirt area. Such pistons can thus withstand the demand for higher load and highet performance engine .

 

Cooling Gallery

Created for operation in high temperature environment like turbo engines. Through oil circulation in the gallery, pistons are intensively cooled in the piston crown and ring belt area .

 

Anodized Crown

Anodization of piston crown creates a hard crown surface thus providing pistons with extra protection against crown piting and wear .

 

Tin Coating

Tin coated surface provides extra lubrication and smoother running of cylinder components resulting in longer engine lifetime .

 

Moly Skirt

Help produce less frictional heat and engine noise. The extra lubricative effect also minimize cylinder bore wear and prevent piston scuffing .

 

Phosphating

Reduce tge fructuib from with the cylinder liner . And to protect the piston from corrosion .

 

Nitriding

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