1. Safety and comfort

The application of four-valve technology effectively reduces engine intake and exhaust noise; the rear gear chamber and advanced point-line meshing gear technology reduce powertrain mechanical noise.

2. Fuel and money saving

The application of four-valve technology ensures a substantially increased flow area for intake and exhaust. The central fuel injector enables more uniform atomization and more complete combustion. The P pump and P nozzle ensure higher injection pressure and stronger working capacity, with more reasonable matching between the fuel injector and combustion chamber, uniform mixing, and the best fuel atomization quality. This results in a more than 15% reduction in mechanical loss and less pumping loss, as well as a 10-15% reduction in fuel consumption compared to engines at the same power level.

3. Reliability and durability

The Yuchai YC6T product, adhering to stringent mechanical development verification specifications, has undergone a cumulative durability bench test of 20,000 hours. The one-head-per-cylinder structure ensures easy maintenance. Cylinder head bolts are evenly distributed and stressed. The valve system, high camshaft arrangement, short and thick push rod, and roller tappet contribute to the product's high reliability. Advanced equipment and quality control from casting to assembly ensure superior quality.
