Advantages of CCEC K38 – DM746 Auxiliary Engine
Four-valve per cylinder design optimizes air/fuel mixture. Improves combustion and emissions. High-strength alloy casting, can withstand higher impact. Each cylinder has a cover, and the oil supply and oil return pipelines are drilled inside the cylinder head, with a simple structure and easy maintenance. Dual camshaft design for precise control of valve and injection timing.
Integral crankshaft made of high-strength forged steel, rounded corners and crank necks are subjected to induction hardening treatment, and the fatigue strength of the crankshaft is higher. The piston is made of aluminum alloy casting, and the design of the w-shaped head and the barrel-shaped skirt can compensate for thermal expansion and cold contraction to ensure a good fit.
High-capacity gear pumps provide pressurized oil to lubricate bearings and cool pistons. All pressure lubricating oil passages are drilled in the cylinder block and inside the cylinder. Oil cooler, full flow filter.
