1.An intermediate shelf is provided in the cylinder head to enhance rigidity and cool the combustion area efficiently. 2.Exhaust valve is made of heat-resistant alloys and its seat area is reinforced cobalt-based heat-resistant alloy to prevent high-temperature corrosion and wear. Tufftlide treatment is applied to the cylinder liners for excellent wear resistance. 3.The piston comprises a high-strength, heat-resistant steel crown and a high-strength, tough forged aluminum body. The durability of the piston at high outputs has been improved by the use of a forced cooling system. The constant temperature cooling system with thermostat gives optimum combustion.

1.Fuel consumption at rated output is only 145 g/PS·h. 2.The high-pressure injection pump together with optimum cam profiles and injection nozzles realizes high-pressure injection of 1500 kgf/cm2 and reduces the injection period to further increase combustion efficiency. 3.NOx emissions and smoke have been reduced by improving the matching between the piston combutsion chamber shape, compression ratio and fuel injection timing.

All the maintenance and servicing of the equipment, including the fuel injection system, is located on one side while the exhaust and cooling water pipings are installed on the other for easier access. The main bearing and cylinder head can be tightened easily and securely using an hydraulic device. A large inspection open is provided so that assembly and desassembly of the piston and main bearing can be done inboard and the major component parts are light enough and split into smaller components for easier handling. Rocker arms, pumps and turbochargers are forced lubricated with oil from the engine oil pan to lessen the daily maintenance.

All pumps, oil coolers and filters in the cooling water, lubrication and fuel systems are compactly installed on the engine which enhance comfort in the working area and provide an affordable space. The overlap distance between the crankshaft main journal and pins has been increased to reduce the cylinder pitch, thus reducing the overall engine length.

CRT data logger engine monitoring system
The engine monitorting system allows the remote monitor of all operations from the wheel house; the operator can check the condition of the engine in graphic too.
