240/275 diesel engine piston for locomotive

240/275 diesel engine piston with steel crown and aluminum skirt :

The high effect oscillating cooling was adopted in the composite piston with steel crown and aluminum skirt that can satisfy the high-duty request of diesel engine.

The piston crown closed die forging with high quality alloy steel and heat refining, so it may endure higher mechanical load and heat load. The piston ring groove way carry on uprating disposal in surface according to customers request, it will raise wearability. and life of the piston.

The piston skirt closed die forging by whole fibre with eutectic alpax alloy, the skirt is light , small heat expansion coefficient and good wear resistance.

The mold line of piston skirt was adopted medium bulge changing into ellipse, so the fit clearance for cylinder is small and have a good gas tightness, the running of piston is stable in order to reduce attrition in cylinder.

The crown and skirt was joined by bolts, it is convenient to separate and install. It has a good reliability and could be exchanged by single part.
