YC6TD Details
YC6TD Series — Product Description
- 1. Reliability & durability: YC6TD has passed a cumulative durability bench test of 20,000 hours. Alloy cast-iron block and integral forged-steel crankshaft improve fatigue strength and wear resistance. One-cylinder-one-head architecture eases maintenance; evenly stressed head bolts. High camshaft, short & thick push rod and roller tappet enhance reliability.
- 2. Fuel & money saving: Four-valve design and central injector boost breathing and atomization for more complete combustion. Turbocharged & intercooled with electronically controlled pump for precise fueling. Holset/Lianxin turbo delivers wide economic operating range, >15% lower mechanical loss and 10–15% lower fuel consumption vs. same-power engines.
- 3. Safety & comfort: Four-valve layout reduces intake/exhaust noise; rear gear chamber with point-line meshing gears lowers drivetrain mechanical noise.
