1. Reliability and Durability

The Yuchai 6TD product, adhering to stringent mechanical development verification specifications, has undergone a cumulative durability bench test of 20,000 hours. The engine block is constructed from alloy cast iron, offering higher strength. The integral forged steel crankshaft enhances fatigue strength and wear resistance. The one-head-per-cylinder structure ensures ease of maintenance. Cylinder head bolts are evenly distributed and stressed. The valve system, high camshaft arrangement, short and thick pushrod, and roller tappet contribute to the product's high reliability.

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 turbocharged and intercooled, electronically controlled pump technology, along with precise electronic control, helps users maximize the efficiency of every drop of fuel. The Holset/Lianxin turbocharger provides a wide range of economic operating conditions, a mechanical loss reduction of over 15%, less pumping loss, and a 10-15% reduction in fuel consumption compared to engines of the same power level.

3. 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.
