Advantages of K38-DM969 Marine Auxiliary Engine
- Four-Valve Design and Alloy Casting – Four-valve per cylinder design enhances air/fuel mixture, optimizing combustion and emission performance. Crafted from high-strength alloy casting, it endures substantial impact. Each cylinder is equipped with a cover, featuring oil supply and return pipelines drilled inside the cylinder head for easy maintenance. Dual camshaft design ensures precise control of valve and injection timing.
- Integral Crankshaft and Piston Design – The integral crankshaft, forged from robust steel and subjected to induction hardening treatment, exhibits higher fatigue strength with rounded corners and crank necks. The aluminum alloy casting of the piston, designed with a w-shaped head and barrel-shaped skirt, compensates for thermal expansion and contraction, ensuring optimal fitting.
- High-Capacity Gear Pumps – High-capacity gear pumps deliver pressurized oil, ensuring efficient lubrication for bearings and piston cooling. All pressure lubricating oil passages are intricately drilled within the cylinder block and cylinder. The inclusion of an oil cooler and a full-flow filter further enhances the engine’s performance and durability.
