The cylinder body is mainly made of gray cast iron and vermicular graphite cast iron with use of strict technical control in the production process to make sure deformation on the upper plane of the cylinder body is no more than 0.05mm within every 50mm. For cast iron cylinder body, error of six-cylinder engine throughout its total length shall not exceed 0.30mm and that of four-cylinder engine not exceed 0.20mm, and for aluminum alloy cylinder body, error of six-cylinder engine shall not exceed 0.50mm and that of four-cylinder engine not exceed 0.30mm. Cooling spray shot test is carried out to further improve its reliability. Reinforcing rib built inside the cylinder body guarantees its strength and properly arranged coolant way and lubricant way ensures proper cooling and lubrication.
The integration of crankshaft, postposition gear chamber and point-line gear-meshing patent technology reduce noise level
Wet cylinder liner structure facilitates maintenance and repair
Improved fuel consumption by P7100 fuel pump, P-injector and Honeywell turbocharger achieves high mean effective pressure and power density
The use of 42CrMo forged steel crankshaft increase fatigue strength and abrasive resistance, and the torque output at front end could be more than 900Nm
Yuchai sealing technology in piston ring and valve oil seal reduces the lube oil consumption
High fuel efficiency and low maintenance cost
Operator and nature friendly with low noise, rapid start ability and low emissions
Major overhaul period is more than 12000 hours
