Compared with water-cooled diesel engine, air-cooled diesel engine has its particular virtues such as simpler structure, higher efficiency, easier cold-starting, higher adaptability and easier maintenance.

The paper presents the main technical specifications, design ideology, structural and technological features,performance indexes and application scope of the high overate super light single-cylinder series air-cooled diesel .

By studing and improving the design the wind guide cover,anti-atraw dish,flow deflector and wind guide plate of the original product of light air-cooled diesel engine,we make the cooling wind field well distributed.

The water around the dredge is muddy and full of impurities, causing a lot of troubles to the equipment and pipes of traditional diesel engine cooling water system.

Piston crowns made from this material wereassembled in 6105 cooling-free diesel engines, the diesel engine constructed was rig-tested for morethan 700 hours.
