The Hatz 1B30 is a robust, compact diesel engine designed for industrial equipment where reliability, simple installation and straightforward servicing are priorities. The B‑series datasheet specifies the 1B30 as an air-cooled 4‑stroke diesel with 1 cylinder, 0.347L displacement, and mechanical direct injection, making it a practical choice for OEMs building compact equipment packages and for like-for-like engine replacements.

For performance, the datasheet lists the 1B30 at up to 5.0 kW / 6.7 hp @ 3600 rpm (intermittent loading, constant speed), and 4.6 kW / 6.2 hp @ 3000 rpm (constant speed). For variable-speed applications, the table also shows 5.0 kW / 6.7 hp @ 3600 rpm and 4.6 kW / 6.2 hp @ 3000 rpm, with additional points such as 4.5 kW / 6.0 hp @ 2800 rpm and 4.2 kW / 5.6 hp @ 2600 rpm.
