Crankshafts after machining shall undergo 100% safety test of crankshaft body on bending fatigue performance and magnetic flaw detection to guarantee its high safety factor and reliable quality. Safety test of crankshaft body on bending fatigue performance shall ensure safety factor of iron crankshaft higher than 1.6 and of steel crankshaft higher than 1.8. The product employs exquisite thermal treatment technique for overall tempering of steel crankshaft, normalizing treatment of iron crankshaft and quenching or nitriding treatment of crankshaft surface. 100% magnetic flaw detection is required for the crankshaft after machining, followed by demagnetization treatment. It is required that magnetic strength shall be ≤5 gauss.
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
