R Series Diesel Engine

SDEC\'s SC 25E/28R series engine is a newly introduced and developed small-displacement diesel engine after SDEC joined SAIC, and it can fully meet the National IV and the National V Emission Standard. This engine is introduced from the Italian VM Company, embodying advanced technology and sophisticated craft, and it is mounted in many of the worldwide best-selling vehicle models including Alfa Romeo, Chrysler Voyager, Land Rover Defender, JEEP Cherokee, and LDV. During the process of introduction and production, SDEC inherited its sophisticated manufacturing process and outstanding performance, ensuring the product quality. With the development of the domestic auto market, this engine will be a preferred power for many domestic diesel vehicles.

Technologies	Functions	Advantages
16 Valve Cylinder	Increase the inlet flow	Improved the engine performance (horsepower and torque)
The second generation BOSCH high pressure share-rail fuel system,CP1H oil pump	Each cycle can spray five times, maximum fuel injection pressure can reach 1600bar, and the flow deviation of the fuel injector can be controlled.	Lower emission, noise and fuel consumption for the engine
Electronic control and variable cross-section supercharger VGT/FGT, optional	Wider engine torque, faster engine dynamic response	Improved the driving performance of the finished vehicle, lower emission and fuel consumption
Tappet roller pin	Reduce the height and friction losses for the engine	Smaller dimensions for the engine and reduced the fuel consumption
Hydraulic gap adjuster	Automatic adjustment for the valve clearance	No need to adjust the maintenance work for the valve gear
Share-rail pressure control valves	Better control for the share-rail pressure	Improved the driving performance of the finished vehicle, the stability of the cold start and the engine operation
DOHC(Double Overhead Camshaft)	Increase the cooling fluid and air flow rate and improve the engine performance	With improved engine power
