Structural and Design Differences
F4L912
Small displacement, compact structure, and relatively light weight.
Output is generally in the 30–50 kW range (depending on speed and application).
Suitable for continuous low-speed operation with relatively low load requirements.
F4L914
Larger displacement, slightly increased bore and stroke, slightly larger overall size and slightly heavier.
Output is generally 50–60 kW or even higher (depending on the specific version).
Enhanced torque performance, suitable for heavier loads
Typical Application Comparison
F4L912 Common Applications
Suitable for small to medium power requirements, high reliability, and simple maintenance:
Diesel generator sets (small to medium size)
Water pump sets / Irrigation pumps
Light construction machinery
Hydraulic power pumps / Compressors
F4L914 Common Applications
Suitable for medium power requirements and heavier loads:
Agricultural machinery power (e.g., tractors, agricultural equipment)
Medium-sized generator sets
Construction machinery (mud pumps, large water pumps, mixers, etc.)
Industrial power output
