Product family · Air cooled diesel engine
Deutz air-cooled diesel engines
Six air-cooled families listed from 6.8 kW to 410 kW — FL511 at the small end, the 912, 913 and 914 families in the mid-range, and FL413 and FL513 at the top.
Air-cooled Deutz engines are the historical core of this catalogue. The supplier's own listing describes the FL413 family with the phrases European production technology, modular single-cylinder arrangement and cold-starting ability under extreme climatic conditions, and lists applications in construction, mining, road and oilfield construction machinery. Those are the catalogue's words for the family — use them as the starting point, then work from the power bands below.
The families stack by cylinder architecture and output. The FL511 is the small end of the range. The 912, 913 and 914 families are the mid-range core that most replacement enquiries ask about, and the FL413 and FL513 families carry the high end. Within each family, output depends on cylinder count and rating speed, so the family band is a routing tool, not a specification: the specification is the listed table for the exact model, such as the F4L912 figures reproduced on its own page.

Reading the family bands
A family band such as FL912 at 14–85 kW covers several cylinder counts and several rating speeds. When you enquire, name the exact model — F3L912, F4L912, F5L912 or F6L912 — and the rating point you need. The F4L912 listing, for example, publishes four rating points for the same engine: 32 kW at 1,500 rpm, 38 kW at 1,800 rpm, 46 kW at 2,300 rpm and 51 kW at 2,500 rpm. Quoting or comparing that engine without a speed is meaningless, which is why every figure on this site is carried with its listed speed where the catalogue states one.
For the FL413W table, the catalogue lists the F6L413FW through BF12L413FW at a single speed of 2,300 rpm with maximum torque figures at 1,500 rpm. If your application is a continuous-duty drive rather than an intermittent machine drive, say so in the enquiry and confirm which rating basis the quoted model is listed on before you order.

Buyer questions
Why do the same family and model show several power figures?
Because the catalogue lists the model at several speeds. The F4L912, for instance, is listed at 32 kW at 1,500 rpm and 51 kW at 2,500 rpm. Quote the speed your application runs at.
Which air-cooled family fits construction machinery?
The catalogue lists the FL413 family's applications as construction, mining, road and oilfield construction machinery. The 912 and 913 families are the most common replacement enquiries across machine types — send the nameplate designation and confirm the match.
Are parts still listed for these families?
Yes — the parts catalogue groups Deutz parts by series, including 912, 913, 914 and 413 series groups. See the Deutz engine parts page.
