CCEC provides both heat exchanger cooling and radiator cooling marine auxiliary engines, which mainly using for marine main generator and marine emergency generator.
For the emergency generator set applications, we provide additional options for customers such as dual starter motor system (we provide both electric and spring starter motor for customers), which are required by most of international classifications.
All of CCEC marine auxiliary engine are comes with dry type exhaust system, which means dry type exhaust manifold and dry type turbocharger, SeaMac provides upgrading services for water-cooled exhaust system, which modify dry type exhaust system into water-cooled exhaust system, which are quite important and often requested by passenger boat projects.
Advantages of CCEC K38 – DM821 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.
