G Series

Power Output: 162-363 kW

The G series in-line diesel engine (SC13G/SC15G) is improved on the basis of the G128 Xinlong marine diesel engine. The series engine has been upgraded significantly in reliability, fuel economy, NVH and appearance. The SC15G engine’s stroke is extended to 165 mm.

The engine is modularly designed. Most parts of the G series in-line engine are interchangeable with those of the G128 Xinlong marine diesel engine, offering easy maintenance. Its long maintenance interval and proven reliability ensure high uptime and low maintenance cost. The series engine is a first choice for the marine power of 162 to 363 kW.

Major Improvements

Improved gaskets for all sealing areas, changed fuel injection pump connection from drive shaft structure to gear connection and adopted a non-quenched and tempered steel crankshaft for the SC15G engine in order to enhance engine reliability.

Enhanced water pump flow, and optimized pipeline design to reduce system resistance.

Increased oil pump flow and oil pressure to improve lubrication of internal moving parts.

Added oil separator, and redesigned thermostat to improved application adaptability to regions of different ambient temperatures.

Redesigned fuel line, optimized layouts of outside piping, air filter, as well as guard and shield to make engine appear in good industrial design.

Utilized fractured connecting rod to provide easier maintenance and service.

Employed an air-to-water intercooler with core removable by easy pull out to facilitate easy cleaning and maintenance, resulting in low maintenance cost.

Integrated heat exchanger with expansion tank to reduce engine size and cost.
