Product Description
The YC6J series marine diesel engines, developed with advanced German and Japanese marine technology, are designed for small ships and fishing vessels. These engines feature high-strength alloy-cast cylinder blocks and heads, ensuring rigidity and reliability. With an integral crankshaft and sliding bearings, they offer a compact design, light weight, and high durability, with an overhaul period exceeding 10,000 hours. The necking combustion technology, AD-type high-pressure fuel pump, and low-inertia injectors ensure efficient combustion and superior fuel economy, outperforming domestic competitors. Yuchai’s proprietary piston ring and valve seal technologies reduce lubricating oil consumption by over 50%. Ideal for small vessels and 50-100kW marine generator sets.
