G32 Series Marine Diesel Engine

In response to the increasingly high requirements for engine reliability from boaters in shipping industry, we developed the G32 series marine diesel engine. As one of the boat parts, the propulsion engine boasts cutting-edge technology and wonderful performance, keeping ahead on the home market and reaching the world advanced level at the turn of this century.

The marine diesel engine is designed to have efficient turbocharger that is conducive to control the emission of exhaust pollutants such as nitrogen dioxide. High-pressure fuel injection system components, as well as intercooler with moderate cooling effect, are also adopted so as to meet requirements for nitrogen dioxide emissions of the International Maritime Organization (IMO). The exhaust smoke under all working conditions is controlled within 0.3Bosch, thus achieving running with no visible smoke.

The G32 series marine dieselengine is a turbocharged, four-stroke, water cooled, directly injected and irreversible one with a charging air cooler. The engine is available in 6-, 8- or 9- cylinder types, with the output ranging from 2665kW to 4400kW. The machine can be operated on heavy fuel oil of 380cSt/50℃ or 3500 sec.Red.No.1/100℉.

1. Engine block without cooling water chamber

The G32 series marine diesel engine is using an inverted main bearing structure. By using two main bearing studs fastened by hydraulic stretching tools, and two studs laterally pulled tightly together at left and right sides of the engine body, the main bearing cap is connected with the engine body to form a structure with sufficient strength and stiffness to resist torsion and bending.

2. Fully balanced crankshaft
The crankshaft is made of high-quality alloy steel by overall continuous fiber forging. Special method is taken to achieve a thorough balancing of each cylinder. Large size balancing blocks are provided on each of the crank to perfectly counterweight the unbalanced centrifugal force. The mechanism improves the distribution of crankshaft stress and bearing load, ensuring the safe operation of the crankshaft.

3. Intercooler box
The intercooler of the marine diesel engine is manufactured by GEA company. The cabinet is of drawer-type structure, and the core is divided into two parts for high and low temperatures respectively. It is easy to mount the core from the side of the box or remove it for cleaning.

4. Monitoring system
The G32 series marine diesel engine is equipped with a set of SB-ZJ-II MCU monitoring and control system with SB-LC type operation box and 64 capacitance level sensor. The system is responsible for real-time collection and monitoring of more than 50 important operating parameters, such as main bearing temperature, lube oil, cooling water, and intake and exhaust temperatures of each cylinder. The system will give alarms upon limit crossing. Safety devices are provided for stopping the marine diesel engine in cases of over speed and low oil pressure, ensuring the reliability of the boat motor.

5. Easy to use and maintain
The G32 series marine diesel engine is equipped with electric barring device, reducing the labor intensity of operators. The intercooler is of drawer-type cabinet structure, which is easily installable, removable, and washable. The powerful bolts, including the cylinder head bolts, main bearing bolts, and the laterally tensioned studs, can be tightened or loosened by using hydraulic tensioners and special tools, so that the maintenance work is both convenient and easy.

The G32 series marine diesel engine can be used as the main engine of the following ships:
Ro-Ro vehicle ships, Oil tankers, Container ships, Bulk carriers, Tugboats, Fishing ships, Dredgers, Naval ships, AHTS.
