Hatz 1B30 Engine 

The 1B30 Hatz engine shares the same single-cylinder, air-cooled architecture as the 1B20 while delivering greater performance. An 80.0 mm bore and 69.0 mm stroke give a 347 cc displacement, with power ranging from 2.6 kW at 1,500 rpm up to 5.4 kW at 3,600 rpm. Recoil or electric starter options are available at 12V or 24V.



Common applications include mid-range construction equipment, pump set drives for agricultural and irrigation operations, remote power generation, and light industrial machinery across mining and resources sectors.

1B20 Hatz Engine vs 1B30: Which Model Suits Your Application?

Both models share a compact, air-cooled, direct-injection design. The 1B20, at 243 cc, suits applications where weight, footprint, and lower power output are the primary considerations. The 1B30, at 347 cc, is the better fit where a higher power envelope and greater torque are needed without moving to a two-cylinder unit. Renseal can help confirm which model aligns with your load requirements. Call 03 9794 5711 for a discussion.
