Single point fuel nozzle refers to the fuel nozzle with only one fuel injection port, which is simple and reliable in structure, low in manufacturing cost and wide in use. It is commonly used in internal combustion engines such as automobiles and motorcycles, and has the following advantages:
1. High injection accuracy, can meet the needs of efficient combustion, improve engine power and fuel economy.
2. Low maintenance cost, easy to install and replace.
3. Easy to adjust, size and flow can be adjusted according to the needs of the engine.
However, because the single-point nozzle has only one fuel injection port, its fuel injection is limited, and it is not suitable for high-power engines, which is easy to cause incomplete combustion.


 

Two, multi-point fuel nozzle

Multipoint fuel nozzles are fuel nozzles with multiple fuel injection ports, which are complex in structure and suitable for high-power engines. It is suitable for cars, aircraft, ships and other power machinery, with the following characteristics:
1. Uniform fuel injection can meet the needs of high-power engines and improve combustion efficiency and fuel economy.
2. Different fuel injection amounts can be achieved, and flow and size can be adjusted according to the needs of the engine.
3. Suitable for use in high-speed and high-pressure environments, with high reliability.
However, the manufacturing difficulty and cost of multi-point nozzles are relatively high, and the adjustment and coordination of various parameters need to be considered when used, which is not easy to control.


 

Three, direct injection fuel nozzle

The direct injection nozzle is also known as the direct injection nozzle in the cylinder, which is different from the traditional injection method, and the fuel is directly injected into the combustion chamber of the automobile engine, which can make the fuel burn fully and improve the fuel economy. It is suitable for high-efficiency combustion engines and has the following characteristics:
1. The oil and gas mix is more full, and the combustion is more complete, which can improve the power and fuel economy.
2. Can achieve fuel injection adjustment under different working conditions, suitable for different driving modes and working environments.
3. The manufacturing difficulty and cost are also relatively high, requiring higher technical level and precision.
 
In short, different types of fuel nozzles have their own characteristics and scope of application, and the appropriate nozzle type needs to be selected according to different use environments and needs.
