First :the role of excavator engine

Excavator engine is one of the core components of excavator, its main role is to provide power and drive the operation of the whole excavator. Specifically, the role of the excavator engine includes the following aspects:

1. Provide motivation

The excavator engine burns fuel and air to convert chemical energy into mechanical energy to provide power and drive the excavator. The power generated can be controlled by adjusting the throttle to meet the specific operation requirements.

2. Rotate hydraulic pump and hydraulic motor

Most of the hydraulic equipment of the excavator needs to be powered by the engine, such as hydraulic pumps and hydraulic motors. The power output of the engine rotates the hydraulic pump, producing hydraulic energy, which is then converted into mechanical energy by the hydraulic motor, thus driving the operation of the entire hydraulic system.

3. Auxiliary equipment such as drive wheel transmission system and hydraulic fan

In addition to the hydraulic equipment, the auxiliary equipment such as the wheel drive system and hydraulic fans of the excavator also need to be powered by the engine to operate normally.

Second:the working principle of the engine

The working principle of the excavator engine is similar to that of an ordinary car engine, which completes four working cycles of suction, compression, explosion and exhaust through four throttle valves and the piston in the cylinder, converting the chemical energy generated by fuel combustion into mechanical energy to provide power.

There are two types of excavator engines: water-cooled engines and air-cooled engines. Water-cooled engines use cooling water to dissipate heat from the engine, while air-cooled engines use air flow to dissipate heat.

In general, the excavator engine is one of the core components of the excavator, and its role is to provide power and drive the operation of the entire excavator. Understanding how the engine works is very important for timely detection and resolution of problems, but also allows operators to better understand the performance and operational requirements of the machine.
