What is the difference between Delong no-load and heavy-load?

[LeGrant]

Delong no-load and heavy-load differ in their maximum rotational speeds. Below are the relevant details: 1. Maximum rotational speed: In no-load mode, the engine limits the maximum rotational speed, and the power output is only about 30% of the rated power. In medium-load mode, it outputs about 60%, while in heavy-load mode, it can output the full power. 2. Electronic control unit: During Delong no-load and heavy-load conditions, the electronic control unit automatically limits the engine's torque and rotational speed based on different working conditions, ensuring the engine operates within specified torque and speed ranges. This reduces additional power consumption, thereby improving overall fuel efficiency.
