YC6T series diesel engine


Type characteristic
Through deep cold and hot impact test, high temperature, high cold test, crankshaft fatigue test and more than ten verification, accumulated 20000 hours durability bench test;
The body is made of alloy cast iron and has higher strength; the high strength alloy connecting rod is more reliable in movement;
Internal cooling oil path piston, one ring cooling technology, reduce piston temperature, engine oil consumption, improve piston reliability
Four valve technology, effectively reduce the engine intake and exhaust noise; rear gear chamber and advanced point line meshing gear transmission technology, mechanical noise
The mechanical loss is reduced by more than 15%, the pump loss is smaller, and the consumption is reduced;
Electric and gas dual energy can be used to meet the safety requirements of chemical and other special ships.
