The Hatz 1B30V is a 0.3 L (347 cc, 21.18 cu·in) natural aspirated single-cylinder four-stroke air-cooled internal combustion small diesel engine with a vertical shaft, manufactured by Motorenfabrik Hatz GmbH & Co. KG for general-purpose applications.
The Hatz 1B30V engine has a single-cylinder, light-alloy cylinder head, forged crankshaft, valve timing via rocker arm, pushrods, finger-follower, and camshaft. The Hatz 1B30V engine can be equipped with a recoil or electric starter (12V or 24V) and alternator (14V – 14A at 3,000 rpm; 7A at 1,500 rpm or 28V – 7A at 3,000 rpm or 4A at 1,500 rpm). The engine used pressurized lubrication with a fine filter in the main flow. The 1B30V is equipped with a 5.0 L (1.32 US. gal. 1.1 Imp. gal.) fuel tank.
This diesel engine produced from 3.5 PS (2.6 kW; 3.5 HP) at 1,500 rpm to 7.3 PS (5.4 kW; 7.2 HP) at 3,600 rpm of horsepower (ISO 1585) and 17.5 Nm (1.79 kg·m; 12.92 ft·lb) at 2,300 rpm of peak torque.
