The SC13G/15G series engine is a product improved and designed by Shanghai Diesel Company based on the original G128 generator set dedicated diesel engine. It has undergone significant upgrades in product quality, reliability, economy, vibration noise, and appearance, with the SC15G stroke extended to 165mm. Most parts of this series of engines are common to the original model and are the preferred supporting power for commonly used generator sets built according to SAIC MOTOR manufacturing standards.

1. The overall crankshaft is made of non quenched and tempered steel, and all sealing gaskets are improved. The fuel injection pump is directly connected by gears, eliminating the transmission shaft structure and improving reliability.

2. Increase water pump flow rate, optimize pipeline design, and reduce system resistance.

3. Increase the flow rate of the oil pump, increase the oil pressure, and improve the lubrication of internal components.

4. Adding oil and gas separation devices and redesigning thermostats can meet the needs of different environmental temperatures in regions.

5. Redesign the fuel pipeline, improve the layout of other peripheral pipelines and air filters, and ensure a reasonable layout with a more industrial design feel.

6. The use of an expansion type connecting rod makes maintenance and repair more convenient.
