Starlight generator


SDEC Generator G Series Diesel Engine Power Output 405 -662KW


The SC25/27G series engine designed and improved by SDEC on the basis of the 12V135 diesel engine special for generator sets. The SC25/27G series engine is characterized by a major upgrade in product quality, reliability, economy, vibration, noise and appearance, especially, the SC27G’s stroke has been lengthened to 155 mm. Most parts of the SC25/27G series engine are interchangeable with those of the original model. Made in accordance with the SAIC MOTOR manufacturing standard, the SC25/27G series is a preferred power for common-used generating sets.

Product Features

1. Engine reliability is improved by adopting one-piece cranshaft made of non-quenched and tempered steel and improved gaskets for all connections.

2. Symmetrical-design of two water pumps and two oil pumps improves cooling and lubrication capacities, reduces water tank volume, and adapts to applications in the regions with different ambient temperatures.

3. Two-section exhaust pipe and optimized leakproof structure reduce probability of leakage. The air intake manifold is changed into casting structure.

4. Redesigned fuel pipeline, improved other outside pipelines, air cleaner arrangement, and guard design, as well as reasonable layout make the engine appear more in sense of industrial design.

5. Fractured connecting-rod provides easy service and maintenance.
