The cylinder block is the skeleton of the engine. The high-quality and solid cylinder block can ensure the leakproofness and shock resistance of the engine.
Our cylinder block is made of gray cast iron, which has good leakproofness and heat dissipation. The design precision is high, which can guarantee the smooth operation of other moving parts of the engine.
Engines with high-quality crankcase will have long life and lower maintenance costs.
Structure: Semi-tunnel type big gantry structure.
Feature 1: The OM457 engine cylinder block outside size is the same but the specific internal dimensions are different.
Feature 2: Because the combustion chamber is set on the top of the piston, so the piston top side temperature is very high. In order to cooling the piston top, piston cooling nozzle are setting on the cylinder wall corresponding to each piston then inject cooling oil to each piston crown.
