9L 32/40 Diesel Engine

Our company is a licensed manufacturer of German MAN32/40 diesel engine. MAN Diesel is a world's leading designer and producer of medium- and low-speed diesel engines. And its MAN diesel engines cover nearly 50% of the power required all over the world.
The 32/40 diesel engines are divided into in-line type and V type, including in-line 6-, 7-, 8-, 9-cylinders and V type 14-, 16- and 18-cylinders. They offer two rotation speeds, namely, 720r/min and 750r/min, with power ranging from 3000 kW to 9000 kW.

1. The diesel engine provides high efficiency, high power density, precombustion chamber structure, spark plug ignition, and stable combustion performance.
2. The single point injection system responds quickly, which offers improved reliability of the air-fuel ratio control and homogeneous combustion in different cylinders.
3. Integrated SaCoSone control system comes with functions of engine control, alarm, detection and safety protection. It can offer remote control of the diesel engine.
4. The reliable diesel engine is very economical and has low emission.

The diesel engine is used in compressor drive, ocean platform drive, industrial power plants, ocean-going vessels, underground gas storage projects, and more.
