Rakennuskoneet Mitsubishi S4S moottori

Mitsubishi S4S Engine: A robust, 4-cylinder, liquid-cooled diesel engine that is widely considered one of the most reliable power plants in the small-to-mid-sized industrial equipment market. The S4S series is frequently favored for its excellent balance of power, fuel efficiency, and structural durability, particularly in environments where machinery is expected to run continuously for long periods.

Engine Configuration: Inline 4-cylinder, 4-stroke, 3.3L displacement.

Cooling System: Liquid-cooled.

Rated Power: Approx. 35 – 55 kW (47 – 74 hp) @ 2500 – 3000 rpm (varies by application/turbocharging).

Fuel System: Mechanical direct injection (highly reliable and easy to service).

Key Advantage: Exceptional build quality, low maintenance costs, and a legendary reputation for "starting in all conditions." Its design is modular and user-friendly for field repairs.

Primary Applications: Forklifts (e.g., Mitsubishi, CAT, TCM, Heli), compact construction machinery (excavators, skid steers), agricultural tractors, and industrial generators.
