Advantages of Automotive Parts Fuel Injector
Ultra-precision fuel injection
Advanced electromagnetic control or piezoelectric driving technology can realize micro-control of fuel injection in an instant. The diameter of the fuel nozzle is ultra-precision machined to ensure that the fuel is injected into the combustion chamber in an extremely fine and uniform mist, so that the fuel and air are almost perfectly mixed, creating ideal conditions for efficient combustion.
Agile dynamic response
It has lightning-fast response speed, and can accurately adjust the fuel injection quantity in milliseconds according to the real-time instructions issued by the engine control unit (ECU). Whether it is a large oil demand when the vehicle is accelerating rapidly or a small supply when it is idling, it can be implemented quickly and accurately, ensuring that the engine is always in the best running state.
Super durability
The internal core components are made of special alloy material with high temperature resistance and corrosion resistance, and the external protective shell is made of high-strength engineering plastic, which effectively resists high temperature, vibration and various chemical corrosion in the engine compartment. After the rigorous durability test, it is ensured that the performance can still be played stably under the long-term and high-intensity use environment, which greatly reduces the failure rate.
Benefits of Automotive Parts Fuel Injector
Power output
Accurate and efficient fuel injection allows the fuel to fully burn and release energy, significantly improving the power and torque output of the engine. The vehicle starts to accelerate more rapidly, and overtaking at high speed is more leisurely, which brings the driver a carefree control experience.
Excellent fuel economy
By accurately controlling fuel quantity, unnecessary waste of fuel is avoided and fuel utilization rate is greatly improved. The fuel cost of car owners’ daily commuting and long-distance driving can be effectively reduced, saving considerable expenses in the long run.
Green environmental protection and emission reduction
The optimized combustion process reduces the emission of harmful gases and particulate matter, helps vehicles easily meet the increasingly stringent environmental protection regulations, contributes to the protection of blue sky and green water, and realizes a win-win situation of driving pleasure and social responsibility.
Application
Widely used in cars, SUVs, MPVs and other passenger cars, as well as light commercial vehicles. It covers many scenes, from daily household scooters to business travel vehicles, and then to urban logistics distribution vehicles, to meet the needs of different user groups for the maintenance and upgrading of vehicle fuel injection systems.
Orientations opérationnelles
Before installation, be sure to cut off the power supply of the vehicle and release the pressure of the fuel system safely. Carefully remove the old fuel injector, and pay attention to the connecting lines and sealing parts to avoid damage. Subsequently, the fuel injector of Zhenhua Auto Parts was installed accurately in the correct direction and position to ensure tight connection and no leakage. After the installation is completed, turn on the power supply, start the vehicle, and observe the running state of the engine and whether there are any abnormal prompts on the dashboard.
Frequently Asked Questions
About working principle
1. How does the automotive parts fuel injector accurately control the fuel injection quantity?
The automotive parts fuel injector contains an electromagnetic coil. When the engine control unit (ECU) sends out an electrical signal, the electromagnetic coil is energized to generate a magnetic field, which attracts the needle valve to open against the spring force. The opening time of the needle valve, that is, the fuel injection pulse width, is precisely controlled by ECU according to the working conditions of the engine (such as idling, acceleration, cruising, etc.). By changing the fuel injection pulse width, the fuel quantity of each injection can be accurately adjusted to meet the needs of the engine at different times and ensure the balance between power output and fuel economy. For example, when idling, the fuel injection pulse width is narrow, and only a small amount of fuel is supplied to maintain low-speed operation; When accelerating, ECU quickly increases the fuel injection pulse width, allowing more fuel to enter the combustion chamber and providing strong power.
2. What will happen if the automotive parts fuel injector is blocked?
The most obvious symptom is that the engine power is insufficient, and the car feels “boring” when accelerating. Because of the blockage, the fuel cannot be sprayed smoothly, and the amount of fuel entering the combustion chamber is reduced, and the energy generated by combustion is not enough to push the vehicle forward quickly. At the same time, it will be accompanied by unstable idle speed, high and low engine speed, like “panting”, which is caused by uneven fuel supply of each cylinder. In addition, the fuel consumption will increase significantly, and the blocked injector may cause some fuel to be poorly atomized, and it will be discharged before it is completely burned. In order to maintain power, extra fuel will be injected, resulting in waste. Exhaust emissions will also deteriorate, emitting black smoke, which is a typical feature of incomplete combustion of fuel, which contains a large number of unburned carbon particles.
About maintenance
3. How to judge whether the automotive parts fuel injector needs to be replaced?
If the above-mentioned blockage symptoms cannot be improved by maintenance measures such as cleaning, it may need to be replaced. In addition, when it is difficult to start, the engine will shake badly even many times during cold start, or it may be that the fuel injector is aging and its performance is declining, and it is impossible to provide the appropriate fuel quantity at the moment of start. In addition, if professional diagnostic tools are used to detect and find that the deviation of fuel injection pulse width is too large and beyond the normal range, it means that its control accuracy has been affected and cannot work normally. At this time, replacing the fuel injector is a better solution.
4. What are the factors that affect the life of fuel injectors?
First of all, the quality of fuel. If you use inferior fuel for a long time, impurities, colloid and moisture will accumulate inside the injector, which will accelerate wear and blockage and greatly shorten its service life. The working temperature of the engine is also very important. The high-temperature environment will make the rubber sealing ring and other parts of the injector age and deform, which will lead to fuel leakage and affect its normal work. Furthermore, the stability of automobile electrical system, if the voltage is unstable and the electromagnetic coil works abnormally, will affect the accuracy and reliability of fuel injection and damage the injector over time. In addition, the use frequency and mileage of vehicles are also one of the factors. For vehicles with high frequency use and high mileage, the fuel injector experiences many working cycles and natural wear is aggravated.
5. What follow-up work should be done after replacing the automotive parts fuel injector?
After the replacement, be sure to check whether the fuel pipeline is tightly connected and whether there are any signs of leakage. This can be judged by observing whether there is fuel leakage around the fuel pipeline after starting the vehicle. Then, use a professional automobile diagnostic instrument to clear the original fault codes related to the fuel injection system, so as to avoid the old fault information from interfering with the ECU’s control of the new injector. Start the vehicle, observe whether the idle speed of the engine is stable, whether the acceleration performance returns to normal, and also check the exhaust emission. If it is still not ideal, it may be necessary to further calibrate the fuel injection parameters to ensure that the newly replaced fuel injector is perfectly matched with the engine to give full play to its best efficiency.
