oil introduce

The fuel injector is actually a simple electromagnetic valve. When the electromagnetic coil is energized, suction is generated, and the needle valve is sucked up, opening the injection hole. Fuel is sprayed out at high speed through the annular gap between the needle and the injection hole at the head of the needle valve, forming a mist, The fuel injector itself is a normally closed valve (meaning that the valve remains closed when there is no input control signal, while a normally open valve is in an open state when there is no input control signal), controlled by a valve needle moving up and down to open and close the valve. When the ECU issues fuel injection instructions, its voltage signal will cause current to flow through the coil inside the fuel injector, generating a magnetic field to suck up the valve needle, Open the valve so that the oil can spray out from the injection hole The biggest advantage of fuel injection is that the control of fuel supply is very precise, allowing the engine to have the correct air-fuel ratio in any state. Not only does it keep the engine running smoothly, but its exhaust gas can also comply with environmental regulations. As one of the key components of electronic fuel injection engines, the fuel nozzle, The quality of its operation will seriously affect the performance of the engine. Blocked fuel injectors will seriously affect the performance of the car. The reason for blockage is due to carbon deposits in the engine on the fuel injectors or impurities in the fuel blocking the fuel injector path. After driving the car for a period of time, the fuel system will form certain deposits. The formation of deposits is directly related to the fuel of the car: firstly, gasoline itself contains gum and impurities, Dust, impurities, etc. brought in during storage and transportation can accumulate over time and form deposits similar to oil sludge in parts such as car fuel tanks and intake pipes; Secondly, due to the reaction of unstable components in gasoline at a certain temperature, gum and resin like viscous substances are formed. These viscous substances, when burned in areas such as fuel injectors and intake valves, will turn into hard carbon deposits. In addition, due to urban traffic congestion, cars are often in low-speed and idle conditions, It will further aggravate the formation and accumulation of these deposits. Sediments in the fuel system are very harmful. Sediments can clog the needle valves and valve holes of the fuel injectors, affecting the working performance of precision components of the electronic injection system, leading to a decrease in power performance of the fuel injectors; Sediments can form carbon deposits in the intake valve, causing it to not close tightly, resulting in unstable engine idling, increased fuel consumption, and worsening exhaust emissions; Sediments can form hard carbon deposits in areas such as the piston crown and cylinder head. Due to the high thermal capacity and poor thermal conductivity of the carbon deposits, it is easy to cause engine malfunctions such as knocking; In addition, it will also shorten the lifespan of the three-way catalytic converter. The working quality of the fuel injectors plays a fundamental role in the power output of each engine. Due to poor fuel quality, the fuel injectors may not work properly, resulting in severe carbon buildup in the cylinder; The accelerated wear of cylinder barrels and piston rings can cause unstable idling, increased fuel consumption, weak acceleration, difficult starting, and excessive emissions. In severe cases, it can completely block the fuel injectors and damage the engine. Therefore, it is necessary to clean the fuel injectors regularly. Long term non cleaning or frequent cleaning of the nozzles can have a negative impact. As for the issue of cleaning time, it should be determined based on the vehicle condition and the quality of fuel added in daily life, Generally speaking, good vehicle condition and good fuel quality can be extended to around 40000 to 60000 kilometers. When the fuel injector is slightly blocked, it can also have a certain impact on the vehicle condition. Sometimes, such faults may occur: when shifting to first gear, starting, the car shakes slightly, and when accelerating in high gear, such phenomena disappear again. Assuming that various sensors on the vehicle are working properly, the throttle valve has been cleaned, and the circuit is also normal, it is likely that the fuel injector is slightly blocked. However, when accelerating in high gear, It is possible that slight gum has been sprayed (dissolved) again, and the performance of the car has been restored. In such cases of slight clogging of the fuel injectors, it is generally not necessary to clean them because slight gum can be dissolved. Therefore, in daily driving, it is necessary to run on the highway frequently to reduce the possibility of carbon accumulation. When the gasoline quality is poor or the vehicle has been driving for a long time, if the fuel injectors are not cleaned for a long time, this clogging phenomenon will be more serious, This can cause poor fuel injection, poor fuel injection angle and atomization, resulting in poor operation of the engine during idle, acceleration, or full load conditions, leading to a decrease in engine power, an increase in fuel consumption, increased emissions pollution, and even engine malfunction. Therefore, it is necessary to regularly clean and inspect the fuel injectors to ensure their good operation)

Replacement of fuel injectors for gasoline powered vehicle engines

1. Open the engine compartment cover and lay the vehicle's protective tool - protective cloth; 2. Open the fuse box cover inside the cabin, locate the fuel pump fuse and unplug it; 3. Open the key, start the vehicle until it stalls; 4. Remove the accessory of the fuel distribution pipe (high-pressure common rail) and remove the fixing bolts on the fuel distribution pipe; 5. Remove the connecting wire harness plugs from the fuel injector in sequence; 6. Remove the fuel injector and fuel distribution pipe together; 7. Remove the fuel injector; 8. Install a new fuel injector; (During the installation process, pay attention to ensuring that the fuel injector buckle is in place.) 9. Install the fuel distribution pipe back; Attention: During the process of replacing the fuel injector, after removing the fuel distribution pipe and fuel injector, the opening should be sealed in a clean towel or other materials in a timely manner to prevent dust from entering. 10. Insert the fuel injector circuit plug in sequence; Install the fuel distribution pipe fixing bolts; Install fuel distribution pipe accessories; 11. Insert the fuel return pump fuse; 12. Clean the engine compartment, remove the protective cloth, and tidy up the tools; 13. The replacement of fuel injectors for fuel vehicles has been completed
