We can see from the parameters why Isuzu C240 is suitable for forklifts.


Power range: The power range of Isuzu C240 is below 40kW, which is exactly what forklifts need. Forklifts typically require low to medium power to provide sufficient power while maintaining fuel efficiency.

Number of cylinders: The diesel engine of this forklift has 4 cylinders, which help provide smooth power transmission and ensure balance during forklift handling and transportation.

Rated power/speed: The rated power is 35.4kW, which occurs at 2500rpm and provides the torque and power required by the forklift, suitable for low-speed operations and high torque requirements.

Maximum torque: The maximum torque at 1800 rpm is 139.9 Nm. This is very important for forklifts to provide sufficient power at low speeds, especially when lifting and transporting heavy objects.

Displacement: The C240 diesel engine has a displacement of 2.369 liters and is usually used in conjunction with forklifts to provide sufficient power and fuel efficiency.

Size and weight: The compact size (693 × 551 × 689mm) and relative weight (252kg) of the entire forklift diesel engine contribute to the compactness and flexibility of the forklift's overall design.


In summary, the parameters of the Isuzu C240 diesel engine make it suitable for forklift applications, providing the required power, torque, and reliability. However, the actual selection should also consider the design requirements and working environment conditions of specific forklift models.
