Introduction to the power system of LPG & Gasoline Forklift

The power system of LPG & Gasoline Forklift is one of the core components of the forklift, which determines the performance, efficiency and reliability of the forklift. LPG and gasoline forklifts have their own characteristics and advantages in the design and operation of the power system.

1. Components of the power system

Engine: The core part of the power system is the engine. Both LPG forklifts and gasoline forklifts are equipped with internal combustion engines, but their working principles are slightly different. LPG forklifts use liquefied petroleum gas as fuel, while gasoline forklifts use gasoline. The engine generates power by burning these fuels to drive the movement and lifting functions of the forklift.

Fuel system: The fuel system is responsible for storing and supplying fuel. The fuel system of LPG forklifts includes liquefied petroleum gas tanks, fuel lines and regulating valves. The liquefied petroleum gas tank is usually installed at the rear or side of the forklift, and the gas is delivered to the engine through the fuel line. The fuel system of the gasoline forklift includes a gasoline tank, a fuel pump and a fuel injector. The gasoline is delivered from the tank to the engine and mixed with air through the fuel injector to form a combustible mixture.
Transmission system: The transmission system transmits the power generated by the engine to the driving wheels and lifting device of the forklift. The transmission system includes a gearbox and a differential. The gearbox adjusts the output speed and torque of the power, while the differential ensures that the forklift can travel smoothly when turning.
Hydraulic system: The hydraulic system is used for the lifting operation of the forklift. The hydraulic pump is driven by the engine and the lifting and lowering of the goods are achieved through the hydraulic cylinder. The performance of the hydraulic system directly affects the operating stability and lifting capacity of the forklift.

2. Working principle
Fuel supply and combustion: In LPG forklifts, liquefied petroleum gas is delivered to the engine through fuel tanks and pipelines. The gas is mixed with air in the combustion chamber of the engine to form a combustible gas. Under the ignition of the ignition device, the gas is burned to produce high-temperature and high-pressure gas, which pushes the piston to move, thereby generating power. The working principle of gasoline forklifts is similar. The gasoline is sprayed into the combustion chamber through the injector, mixed with air and ignited to drive the engine to operate.
Power transmission: The power generated by the engine is transmitted to the driving wheels and lifting device of the forklift through the transmission system. The gearbox adjusts the output of power so that the forklift can operate under different working conditions. The differential allows the forklift to have different inner and outer wheel speeds when turning, maintaining stable driving.
Lifting operation: In the hydraulic system of the forklift, the hydraulic pump is driven by the engine to send hydraulic oil to the hydraulic cylinder. The hydraulic cylinder adjusts the height of the fork according to the operator's control instructions to achieve the lifting and lowering operation of the goods. The design and maintenance of the hydraulic system are crucial to the performance and operational stability of the forklift.

III. Performance characteristics
High efficiency: The internal combustion engine of LPG and gasoline forklifts can provide strong power output, ensuring that the forklift can perform well in high-intensity working environments. Its power system design is designed to improve work efficiency and handle heavy-duty tasks.
Flexibility: The design of the power system enables the forklift to operate flexibly in a variety of working environments. LPG forklifts are suitable for use indoors or in poorly ventilated environments due to their lower emission levels. Gasoline forklifts can be used in a variety of environments due to their wide range of fuel supply.
Economical: The fuel cost of LPG and gasoline is generally lower than that of diesel, and long-term use can save fuel costs. In addition, the maintenance cost of these forklifts is relatively low because their engine design is relatively simple and the failure rate is low.
Environmentally friendly: LPG forklifts have lower emissions, which helps improve the air quality of the working environment. Although gasoline forklifts have slightly higher emission levels, they are still lower than diesel forklifts and have less impact on the environment.
