What does electric injection car mean?

1. Electric injection is - electronically controlled fuel injection, measuring the amount of air inhaled in the engine, and then supplying an appropriate amount of gasoline to the engine by high-pressure injection.The computer control process that controls the mixing ratio of air and gasoline is called electronically controlled fuel injection.

2. Electric injection is a kind of engine, which is very different from a carburetor engine, and the operation method is also quite different. When starting the electric injection engine (including the start of the cold car), there is generally no need to step on the accelerator.

3. Electric injection vehicle: it is to measure the amount of air sucked into the engine, and then supply an appropriate amount of gasoline to the engine by high-pressure injection. The computer control process that controls the mixing ratio of air and gasoline is called electronically controlled fuel injection. There is a big difference between the electric injection engine and the carburetor engine, and the operation method is also quite different.

4. Motorcycle electric injection refers to the injection of fuel and air ratio controlled by computer. The electric injection motorcycle uses sensors to feedback the operating status of the engine and then analyzes the reasonable fuel-air ratio;The carburetor will have a little evaporation when generating mixed gas, so it is not good for environmental protection.

5. Electric injection means that it is very different from the carburetor engine, and its operation method is also very different. Electric injection is a kind of engine, which is very different from the carburetor engine, and its operation method is also very different. When starting the electric injection engine (including cold start), there is generally no need to step on the accelerator.

What is the difference between multi-point electric injection and direct injection in automobile engine? Which one is better?

Direct injection is more accurate than multi-point fuel injection injection, burns better, saves fuel, and can achieve greater horsepower. However, direct injection has higher requirements than multi-point fuel injection products, and generally needs to be used with additives.

In terms of oil products, the requirements of in-cylinder direct injection for oil products are higher than those of multi-point electric injection, and the compression ratio is as high as 12. In terms of cost, the price is usually more expensive because the in-cylinder direct injection is more complex than the multi-point electric injection components.

Considering the three aspects of carbon accumulation, service life and oil requirements, multi-point electric injection of automobile engines is better than direct injection.Carbon accumulation situation The multi-point electric injection engine can form a mixture in the intake manifold, so it is easier to form carbon accumulation in the intake duct.

Direct injection car is better than multi-point injection: What is multi-point injection? Multi-point injection literally means that there is more than one fuel injection hole on each fuel injector, which directly injects the fuel into the intake manifold of each cylinder, and then enters the corresponding combustion, with one nozzle for each cylinder.

What is the principle of electric injection vehicle?

1. The electric injection engine adopts an electronic control device. Replace the traditional mechanical system to control the fuel supply process of the engine.

2. Principle: The so-called electronically controlled fuel injection is to measure the amount of air sucked into the engine, and then supply an appropriate amount of gasoline to the engine by high-pressure injection.The computer control process that controls the mixing ratio of air and gasoline is called electronically controlled fuel injection.

3. The principle of the electric injection vehicle is to use the fuel injector to spray gasoline into the intake pipe, intake duct or cylinder in a mist at low pressure, and then mix it with air to form a combustible mixture. There are many differences between the carburetor version and the electric injection version. First of all, their post-maintenance is different.

4. The working principle of the electric injection car: the injection oil is composed of electric oil pump, fuel filter, oil pressure regulator, injector, etc. The command signal issued by the ECU can open the needle valve at the head of the injector and spray the fuel. The sensor receives temperature, mixed gas concentration, air flow and pressure, crankshaft speed and other values and transmits them to the ECU.

5. Fuel injection principle of electric injection vehicle: The fuel injection nozzle is a solenoid valve, which has an electromagnetic coil, a needle valve, an injection hole and a return spring.When the ECU sends a signal to the fuel injector, the electromagnetic coil is conductive, the needle valve is sucked up, and the fuel is sprayed through the gap between the needle valve and the nozzle and enters the intake manifold.

Notes on the use of electric injection engines

1. Electric injection vehicles should pay special attention to the maintenance of the fuel system. It is necessary to clean the oil line regularly and replace the gasoline filter immediately to ensure that the oil supply system is smooth and the fuel injector is well atomized. It is also necessary to regularly clean the throttle valve, replace the air filter, maintain or replace the spark plug, etc., so as to keep the engine efficient, energy-saving and environmentally friendly.

2. Please do not use electric injection motorcycles for a long time. During use, please do not install more powerful electrical appliances without permission. Please do not accelerate suddenly immediately after starting. If the motorcycle is left for a long time, the battery used by the motorcycle may run out of power.

3. The following is an introduction to the precautions for starting the electric injection vehicle: maintenance of the fuel system: the electric injection vehicle should pay special attention to the maintenance of the fuel system. Regularly clean the oil line and replace the gasoline filter in time to ensure that the oil supply system is smooth and the injector atomization is good; regularly clean the throttle valve, replace the air filter, maintain or replace the spark plug. Etc. to keep the engine high-efficiency, energy-saving and environmentally friendly.

4. The engine is prone to failure. Electric injection cars must use clean gasoline, not low-standard gasoline, because gasoline containing impurities produces other impurities during combustion, causing the injector to block. The use of non-standard gasoline will also cause the ternary catalyst to lose its effectiveness prematurely.

5. If the electric injection motorcycle is left for a long time, the battery used by the motorcycle will lose power. The electric injection motorcycleIt should be noted that if it is not used for a long time, it is best to start it every half a month to ensure that the battery has enough power.

The computer control process that controls the mixing ratio of air and gasoline is called electronically controlled fuel injection.

2. Electric injection vehicle refers to a vehicle equipped with an electronically controlled fuel injection system. It is the abbreviation of "electronically controlled gasoline injection engine"; gasoline injection is to use the fuel injector to spray gasoline into the intake pipe, intake duct or cylinder in a fog at low pressure (260~350kPa), and then mix with air to form a flammable mixture.

3. Electric injection is a kind of engine, which is very different from a carburetor engine, and the operation method is also quite different. When starting the electric injection engine (including the start-up of the cold car), there is generally no need to step on the accelerator.

Popularize the car knowledge you don't know

The height of the headlight on the right is higher because there are more obstacles on the right than on the left: pedestrians, motorcycles, electric vehicles, roadblocks, etc., so this design of headlight height can increase me The safety of driving. The different function of the small tail on the roof. Many people like to install it to add beauty to the car, which looks more fashionable and dynamic.

Mainly because the car is metal, the metal itself will shield the wireless signal, so the device that receives the signal should be installed in the shark fin, and then the device should be loaded outside the car.Some models will also be equipped with GPS signals and 4G antennas.

Black smoke: This mixture is too thick, which means that the amount of fuel injection does not meet the standard, which may be caused by the leakage of the fuel injector, the blockage of the oil pipe, or caused by too much carbon accumulation in the engine.
