Product Features

 

Reliable & Durable
-Engineered to strict mechanical validation standards, including thermal shock tests, extreme temperature tests (-40°C to 60°C), crankshaft fatigue tests, and 10+ validation protocols. Max torque: 2,150 N·m.
-European-designed reliability program ensures over 12,000 hours before major overhaul.

Powerful & Fuel-Efficient
-Yuchai's proprietary electronic control technology enables precise fuel injection (high pressure, flexible control), optimized combustion, low noise, and rapid acceleration. Features low-speed high torque with ample reserve.
-4-valve design increases airflow; centered fuel injector improves atomization and combustion efficiency.
-YC-exclusive piston ring and valve seal tech reduces lubricant consumption by 10+% vs. peers.

Safe & Comfortable
-Digital intelligent monitoring systems (local/remote) and integrated cast iron water-cooled exhaust manifold ensure lower cabin temperatures and enhanced safety.
-Noise-reducing patented gearbox design (rear-mounted gear chamber, optimized meshing) outperforms competitors in quietness.
-Complies with CCS marine safety standards. Double-layer fuel rail and high-pressure pipe design.
