What are the advantages of replacing carburetor with EFI?
EFI motorcycles began to appear in the market, and some motorcyclists may not know much about the concept and efficiency of EFI.
Our common carburetor sucks and atomizes gasoline through the negative pressure formed by engine intake. Used for combustion to do work;
The EFI device uses sensors to accurately sense the air intake, and controls the corresponding gasoline injection to burn and do work after computer calculation.
The EFI vehicle is fuel-efficient and environmentally friendly, and it is easy to start in winter.
EFI technology is much more advanced than carburetor.
EFI technology relies on computer to control fuel injection, which is more fuel efficient.
Carburetors have high power and large displacement.
Their combustion processes are all completed in the cylinder, and there is not much difference.
However, the effect and control accuracy of atomized gasoline are quite different.
After the gasoline engine adopts the EFI device, it has laid a solid foundation for achieving good emissions. In addition, because the oil-gas mixture ratio can be accurately controlled, it will bring great benefits to improve the power or economy of gasoline engines.
Simply put, engines provide fuel in different ways. Compared with carburetor engine, the advanced feature of EFI engine is that the computer system is the control core, so that the engine can obtain the best mixture and produce the maximum power output under various working conditions. It can make gasoline burn more fully and thoroughly, improve the output power of the engine by about 5%, save oil by 5% to 20%, and effectively control the emission of harmful gases. Therefore, in developed countries, the manufacture and use of carburetor cars have long been banned.
Although the traditional carburetor engine can meet the fuel supply of the automobile under various working conditions, it can not achieve accurate control, which not only causes fuel waste, but also affects the composition of exhaust emissions. The EFI device only plays the role of automatically controlling the mixing ratio of fuel and air. According to the different driving conditions of the car, such as starting, idling, acceleration and braking, the sensor and computer cooperate to determine the corresponding fuel injection quantity and the best time, and the fuel supply can be cut off in time, which not only saves fuel consumption, but also fundamentally improves the exhaust emission by adjusting the air-fuel ratio of combustible mixture.
-
As we all know, gasoline needs to be atomized and evaporated before entering the engine cylinder, and it is mixed with air in a certain proportion to form a combustible mixture. The fuel content in this combustible mixture is called the concentration of combustible mixture.
The concentration of combustible mixture should be able to make the mixture burn completely in any cylinder in time. Because the combustion is complete, the combustion releases more heat, which not only makes the engine generate more power, but also controls the harmful substances in the exhaust gas; Timely combustion can reduce fuel consumption and improve thermal efficiency. Therefore, the quality of combustion, that is, whether the combustion is complete and timely, is related to the content of CO and HC in automobile emissions and the utilization degree of heat released by fuel combustion.
Secondly, because the heat release of combustion is mainly limited by cylinder inflation, the greater the inflation, the greater the power and torque of the engine.
The electronically controlled gasoline injection system is an automotive electronic product that can improve the atomization quality of gasoline, improve combustion, control emissions and improve the efficiency of gasoline engines.
Compared with the traditional carburetor fuel supply system, the electronic gasoline injection system replaces the carburetor with a fuel injection device, and the engine power can be increased by 10% by implementing multi-parameter control through microelectronics technology, and the torque can be increased by 20% under the same fuel consumption. The acceleration time from O- 100 km/h is reduced by 7%; Fuel consumption decreased10%; Adopting closed-loop control and installing three-way catalytic converter can reduce indoor gas emissions by 34%-50% and 73%. There are two types of electronic fuel injection systems; Single-point gasoline injection system SPl and multi-point gasoline injection system MPl. Acupoint injection).
After the carburetor truck gives priority to fuel supply, there are some gas distribution problems such as blocked gas path, incomplete combustion and serious exhaust pollution.
Fuel supply of EFI vehicle after priority gas distribution. If the gas path is blocked, the fatigue of the car will not aggravate the pollution, but it needs immediate maintenance.
Can carburetor motorcycle be converted into EFI?
The EFI engine is equipped with many sensors. Your original car is a carburetor, so you can't install those sensors on the engine. Even if you have a full set of electronic modifications, you may not be able to convert it into a truly qualified EFI. Moreover, for ordinary motorcycles, EFI has no obvious advantage except cold start, and this modification is not feasible.

If the vehicle model allows, the cost is high, and it is necessary to increase the vehicle main control board and related mechanical and electronic structural components.
Can EFI change carburetor?
Hello, yes, if you want to be environmentally friendly, it will be big if you change it.
How to change automobile carburetor into EFI
You need to prepare oil pump, computer, intake manifold (many people look at branch pipes), nozzle, throttle, engine harness, ignition coil, etc. It's not worth changing anyway. Might as well buy a used car. If you have friends in this business, you can ask them to help you find it!
