Description

An EFI motorcycle throttle body assembly

the

technical field

Background technique

EFI motorcycle is a new type of motorcycle. According to the load of the engine, the fuel injection nozzle is controlled by the microcomputer to inject fuel to the cylinders that need to work, and the cylinders that do not work do not supply fuel. Compared with traditional carburetor motorcycles, EFI motorcycles are fuel-efficient. Compared with the same type of carburetor motorcycles, they can save more than 20% of fuel; due to the realization of digital ignition and fuel injection functions, fuel consumption is reduced and emissions are improved, so it is better than The carburetor car is environmentally friendly and directly meets the European No. 11 emission standard. At the same time, it also has the characteristics of easy start-up, and the idle speed is stable.

Since the carburetor supplies oil to the engine mechanically, the relationship between the amount of oil supplied and the rotational speed or the opening of the throttle can only be a linear relationship, which cannot guarantee that the air-fuel ratio of the engine can be ideal under all working conditions and all weather conditions. At the same time, when the state of the engine itself changes, the carburetor cannot adapt to changes, resulting in a large amount of energy waste, and it is very unfavorable for combustion, resulting in increased fuel consumption and worsened emissions. The EFI motorcycle adopts the EFI technology, and the carburetor device is canceled by the EFI system device (EFI), and the microcomputer (ECU) with EFI special software is used to carry out real-time intelligent control of the fuel supply and ignition of the engine. It is extremely accurate, so that the air-fuel ratio and ignition angle of the engine can reach the best at any time under any working condition and environment, so that the fuel consumption of the motorcycle is reduced, the emission is improved, and the overall performance is greatly improved.

The EFI motorcycle throttle body assembly is the heart of the motorcycle, and its design affects the engine efficiency and safety performance of the motorcycle. Since the carburetor has been mainly used all the time, the design and development of the EFI system assembly is in its infancy, and many technologies are still immature and need to be further improved.
