G128/SC15G marine engine 244-550hp/180-405KW

G series engines are independently developed and modularly designed based on the characteristics of the marine engine market. They are manufactured according to SAIC MOTOR. Products made according to manufacturing standards. This series of engines excels in product quality, reliability, economy, vibration, noise and appearance. Both models have been significantly upgraded, with the SC15G’s stroke lengthened to 165mm. Most parts of the engine are the same as the original model Universal, widely used in various types of inland river transport ships, fishing boats, engineering ships and other ships as well as 150-300KW marine generators

Features

Mature, reliable and economical The whole machine has a modular design, strengthens the body, adopts an integral cylinder head, a forged steel crankshaft, an expandable connecting rod, and improves all sealing gaskets. The engine is mature and reliable. It adopts electronically controlled single pump combustion technology to easily cope with shipboard emissions.
Strong power and high torque The engine has large displacement, strong power, sufficient power reserve, flat fuel consumption curve in common working conditions, large low-speed torque, and economy. Well, the electronically controlled engine saves more than 5% of fuel than the traditional mechanical pump model.
Strong loading capacity and strong environmental adaptability The engine is strong and durable, with quick speed increase under sudden acceleration. It can meet various working conditions and can adapt to lower grade engine oil, fuel and cooling. liquid and other working conditions.
Convenient maintenance and high attendance rate Most parts are common to the original model, with high maintainability, long maintenance cycle and proven reliability, ensuring high attendance. rate, the engine market has a large inventory, social parts are sufficient, and maintenance costs are low.

Through FEA modal analysis and coupling strength calculation, we improved designs like body strengthening and the installation of an integral cylinder head. 15G adopts integral non-quenched and tempered steel crankshaft to make the fatigue resistance and service life of the engine improved by 30%. The combustion system is optimized. After CFD analysis, the large flow cooling pump and oil pump and new type high-efficiency pressurizer are adopted to have a minimum fuel consumption of 195g/kW.h and a maximum torque of 2300N.m. This realizes the requirements for marine engine of low oil consumption and good acceleration property. After improved designs like flange fuel injection pump drive, added new type oil-gas separation device, optimized thermostat and fuel pipeline, integral heat exchanger and expansion bank and new type sealing gasket, the product quality of this G series product is improved and the visual layout is also more reasonable. This G series engine adopts cracking connecting rod and core-pulling water-air intercooler. The spare parts universality with previous generation product is high, reducing operation cost with convenient maintenance.
