The Hatz 3F35E is part of the Hatz F‑Series of compact industrial diesels, designed for OEM equipment where installation space is tight but durability and serviceability still matter. The datasheet specifies the 3F35E as a liquid-cooled 4-stroke diesel engine with 3 cylinders and 1.102L displacement, giving you smoother running than a single-cylinder platform while keeping the overall package compact.

For combustion and fuel delivery, the datasheet lists mechanical indirect injection in a swirl chamber, which is typically favoured in compact industrial engines for stable operation and proven field reliability. Performance is shown in two duty contexts: for variable-speed applications, the 3F35E is rated up to 18.4 kW / 24.6 hp at 3000 rpm; for constant-speed generator applications, it’s listed at 10.8 kW / 14.5 hp (1800 rpm standby) and 9.4 kW / 12.6 hp (1800 rpm prime). That makes it a practical choice whether you’re driving equipment directly or packaging it into a genset where continuous output definitions matter.

As with all the pages you’re building, keeping the exact model code 3F35E is key for correct supply (governor type, speed setting, flywheel housing, and installation dimensions). If you tell me whether you’re selling it primarily as variable-speed or genset constant-speed, I can make the first paragraph and spec emphasis match your typical buyer intent.
