  With the successive introduction of domestic motor vehicle exhaust emission standards and policies, ordinary carburetors for motorcycles will gradually be replaced by electronic fuel injection carburetors.

  So, what is the difference between an electronic fuel injection carburetor and a regular carburetor? What can replace the original ordinary carburetor?

  （1） Electronic fuel injection carburetor

  Simply put, an electronic fuel injection carburetor relies on electronic components to inject gasoline into the engine combustion chamber, allowing the engine to function normally. The specific working principle is to provide specific data to a microcomputer through electronic components such as air flow sensors and temperature sensors. Then, the computer calculates the appropriate amount of fuel and injects it into the engine combustion chamber. So, electronic fuel injection carburetors supply more precise fuel to the engine and burn more thoroughly, resulting in much less pollution from the emitted combustion exhaust gas and better compliance with national environmental standards. This is why the country advocates the use of electronic fuel injection carburetors on motorcycles.

  In addition, due to the ability of microcomputers to provide engine temperature values through temperature sensors, the proportion of gasoline in the mixture is appropriately increased during motorcycle cold start. Therefore, motorcycles are easier to start and idle more stably in cold conditions, which is a significant advantage compared to ordinary carburetors.

  （2） Ordinary carburetor

  Since the birth of motorcycles, traditional ordinary carburetors have undergone over a hundred years of improvement and refinement, and their manufacturing processes have become quite mature. Its working principle is to use the suction force of the engine piston to draw gasoline from the main measuring hole of the carburetor to the throat for atomization, and then enter the combustion chamber to make the engine work normally. Of course, due to the mature design of ordinary carburetors, they provide faster and more fuel supply during rapid acceleration of motorcycles, resulting in better acceleration performance. This is also a significant advantage of ordinary carburetors.

  The structure of a regular carburetor is simple and the cost is not high. It has better performance in terms of acceleration, and most people can easily grasp its structural knowledge. This makes it easier to eliminate the problems of a regular carburetor. However, due to the exhaust pollution caused by insufficient combustion, it will eventually be eliminated.

  The structure of electronic fuel injection carburetor is complex and the cost is much higher than that of ordinary carburetor. When problems occur, it often requires professionals and professional equipment to repair. However, when starting a cold car, the effect is better than that of ordinary carburetor. In addition, it has less pollution in exhaust emissions and can better meet the national motor vehicle emission standards. Therefore, in the future, motorcycles will fully use electronic fuel injection carburetor.
