First of all, in theory, the electronic injection system is more fuel efficient than the carburetor. Because the carburetor's fuel supply mainly depends on the negative pressure formed during engine operation to suck in fuel atomized substances, its fuel particles are large, the flame transmission speed is slow after burning in the cylinder, and the incineration is incomplete, so the fuel consumption is relatively high, and it is difficult to pass the discharge. Besides, people often hear that their car has a smell of oil after starting, which is the reason, Of course, the carburetor models with good operation conditions do not have this problem.

For the electric injection model, the fuel is supplied by the pressure of the oil pump. The pressure is high, the atomization is good, the flame spreads fast, and the burning is complete. It is difficult to smell the smell of oil unless the electric injection system is defective or the carbon canister is blocked. The EFI system of some other motorcycles can realize the function of losing the throttle and cutting off the fuel, which is widely used in automobiles. That is, after the throttle is released (not in neutral gear), the EFI system stops the fuel supply, which is an incomparable advantage of the carburetor. When acceleration is required, the EFI system resumes the fuel supply. You cannot feel the process, but the EFI system adjusts itself. For example, the electronic injection system of Longxin Wuji 650R has this function.

Then in winter, the cold start performance of the EFI system is good, and it can basically land the car with one shot and stabilize the idle speed by itself. The carburetor is not as good as EFI. You need to manually open the damper, increase the mixing ratio, and manually stabilize the idle speed.

The advantages of the carburetor are simple structure, low cost and simple maintenance. As long as you have the ability to start and grasp a bit of relevant common sense, you can handle the problem yourself, while the EFI system is much more cluttered. If the sensors are broken, you can only replace them, and you can't fix them.

Other carburetors can promote the car manually when all the batteries are out of power, which is of great significance in winter outdoor conditions, but the electronic injection system can not do this. After all the batteries are out of power, all kinds of sensors can not operate normally, let alone start the cart.

However, carburetor models are now increasingly unable to meet the requirements of emission regulations, and the technology of carburetors has not been made a major breakthrough. The development potential has dried up. The EFI system has good advantages and greater development potential. Therefore, it is an inevitable choice for the EFI system to replace carburetors in the s.
