Diesel Engine 12V26/32


Using marine diesel oil and heavy oil, the diesel engine 12V26/32 is primarily used for propulsion power on ships. It can be utilized as the main/auxiliary propulsion unit on ocean-going vessels, naval vessels, main/auxiliary propulsion unit on drilling platforms, semi-submersible drilling ships, offshore multi-purpose work ships, large and medium-sized industrial power plants, crude oil and product oil transfer and booster pump stations, compressors, and others.

Technological Advantages
Modularized common rail technology
The use of the world's most advanced high-pressure common-rail fuel system not only reduces the size of the camshaft and the cost of the engine greatly, but also improves the overall performance including the emission performance. The common rail system consists of two common-rail high pressure oil pumps, the high pressure oil tube, and fuel injector with accumulation chamber. The pressure of the system is 1800bar.

By-pass system
As single-stage ultra-high supercharging can not meet the intake requirement under partial-load conditions for ship drive, the diesel engine is designed with a signal collection system which can automatically control the bypass valve. Therefore, sufficient fresh air can be supplied, which makes the diesel engine better suited for marine propulsion.
