Crews and engineers on mobile machinery rely on robust and efficient engines to ensure smooth operations under demanding conditions. Deutz Marine’s F3L912 engine is a prime example of this reliability. Designed for applications ranging from 24 to 82 kW (31 to 110 hp) at 1500 to 2500 rpm, the F3L912 meets China stage II emissions standards. This air-cooled, naturally aspirated engine features a modular system with single cylinders and a displacement of 3.23 liters. Its compact design reduces installation costs while maintaining high durability and smooth operation, thanks to acoustically optimized components. The robust construction allows for worldwide use, even with high sulphur fuels, ensuring reliable performance under extreme conditions. With a maximum torque of 185 Nm at 1450 rpm and low fuel consumption, the F3L912 delivers optimal engine performance while minimizing operational costs. The engine’s best cold starting performance ensures it can be relied upon in any environment.

Free of charge — send us your request for Deutz Marine equipment. Our team checks it and replies by e-mail.

For marine equipment hardly any maker or authorised dealer will name a price while the vessel is unknown. With the vessel details, availability and price can be settled faster; without them we may have to ask first, which costs a few days. If you are not allowed to name the vessel, a photo of the rating plate is enough — attach it below or send it as a reply to our confirmation e-mail.
