Hatz air-cooled diesel engines

Hatz engines are known for excellent fuel economy and long engine life.

Long engine life features include low piston speed, and an optional 'intelligent' auto-protection device, which stops the engine if the blower drive malfunctions, a low oil condition is encountered, or if the engine is tilted beyond its design parameters.

HATZ engines are designed for durability and robustness. This is achieved by excellent quality control during production. HATZ engines are noted for their reliable starting even at extremely low temperatures.

Easy to service Operation and maintenance are easy for experts and nonexperts. Some of the service features include: automatic hydraulic belt tensioner; automatic injection pump bleeding; maintenance indicator for the air filter; and automatic extra fuel device for cold starting.

For many years, HATZ has led the way in developing environmentally friendly engines. The current engine lines meets EPA Tier 4 standards, as well as CARB and EU regulations.
