SC9DF Product Features
SC9DF engine is an electronically controlled four-valve 9L product developed on the basis of D series by SDEC with consideration of the world's heavy-duty diesel engine development trend and the Chinese working features. Besides some basic performance of SDEC's electronically controlled products, it has the following features:
Four-valve structural arrangement, which improves intake efficiency and has better fuel economy.
Electronically controlled high-pressure shared-rail fuel system, which has injection pressure up to 160Bar, better atomizing effect and more sufficient combustion.
Integrated design of engine oil filtering system. The filter element design gets rid of the integral iron sheet case filter element. The user can change the paper filter element directly, greatly reducing maintenance costs and it is more environmentally friendly.
Exhaust braking technology and engine in-cylinder braking. The compression energy produced by engine inertia is used for braking. The peak braking power is up to 160kW. The complete vehicle fuel economy has been improved and the complete vehicle safety has been greatly enhanced.
