What is the difference between carburetor and electronic fuel injection

In the world of motorcycles, there are always many debated questions. When it comes to the difference between electronic fuel injection and carburetor, I believe few people except for mechanics can answer this question. So what is the difference between them? What are their respective advantages and disadvantages? Below, the editor will introduce to you the differences between electronic fuel injection and carburetor!
What is the difference between carburetor and electronic fuel injection - carburetor
In today's era, carburetors are already a type of fuel supply method that is about to be eliminated. Although the adjusted carburetor is still good in terms of fuel efficiency and performance, under increasingly strict emission regulations, carburetor technology cannot meet the qualified exhaust standards.
The principle of a carburetor is very simple. It is a device that converts liquid fuel into gas, and mixes the converted oil and gas with the air sent in by the throttle valve to form an oil and gas mixture. It is then sucked into the cylinder through the intake valve by the negative pressure caused by the piston in the cylinder for combustion.
The concentration of the carburetor is set from the beginning. If it is necessary to adjust the concentration, the carburetor needs to be disassembled and adjusted, which is quite troublesome. It needs to be modified when going to high-altitude areas. However, carburetors are cheap and easy to maintain, and car dealerships in remote areas usually repair them.
Advantages: Low cost, easy maintenance (can be repaired in most parts of the country), low exhaust sound when using carburetors, and the battery can be pushed when empty.
Disadvantages: The emission regulations cannot support the latest standards, fuel consumption (the difference between perfect adjustment and electronic fuel injection is not significant), difficulty in starting in winter, improper operation may cause the spark plug to flood, inability to adjust the fuel injection concentration according to demand, poor atomization effect, and insufficient combustion,
What is the difference between carburetor and electronic fuel injection - electronic fuel injection
The popularization of electronic fuel injection on motorcycles has been relatively slow, and cars have fully entered the era of electronic fuel injection control. The electronic fuel injection system on motorcycles has just begun to be popularized, and some manufacturers' new models still use the old carburetor system. Electronic fuel injection, as a new technology, is most suitable for adapting to the latest emission standards.
Electronic fuel injection is a relatively complex system, but its principle is actually various sensors that sense the opening and closing angle of the throttle valve, the temperature of the engine, and the position of the crankshaft. These data are transmitted to the driving computer ECU, which calculates and determines when and how much fuel to inject, with precise control.
Due to the various sensors in the electronic fuel injection system, the cost is relatively expensive and the system is complex. Generally, car dealerships are unable to repair the electronic fuel injection system. However, the electronic fuel injection system is relatively stable and not prone to malfunctions.
The most intuitive benefit of using an electronic fuel injection system is that it is very easy to ignite in winter. The electronic fuel injection system will increase the fuel injection amount and enrich the fuel air mixture according to the engine temperature, making ignition easier. Moreover, in high-end cars with more electronic assistance systems, energy-saving mode or power mode can also be selected to save fuel.
Advantages: fuel-efficient, compliant with the latest emission regulations, highly expandable, can automatically adjust fuel injection concentration according to different usage situations, idle speed can be adjusted according to engine conditions, better atomization effect and more complete combustion, without obvious altitude sickness.
Disadvantages: expensive price, inconvenient maintenance, requires professional maintenance personnel, relies heavily on batteries, and cannot be pushed when severely depleted.
