• High pressure common rail system for diesel engine

  The common rail system is one of the most sustainable fuel injection systems due to its unique advantages. The high-pressure common rail system realizes the separation of pressure build-up and injection process, so that the control process is more flexible, can more accurately realize the precise control of small oil volume, and better realize multiple injections.

• How to simply judge the quality of the fuel metering unit?

  The role of the automobile metering unit is to control the oil intake and return flow of the high-pressure oil pump, thereby controlling the oil supply of the oil pump plunger to the rail, meeting the set pressure of the common rail system, and forming a closed loop control of the rail pressure with the rail pressure sensor. The internal structure of the fuel metering unit is not complicated. It consists of three parts: a housing with an electromagnetic coil, an upper cover with an oil hole, and a valve core that can move up and down. When it is damaged, just replace it with a new one.

• What to do if the engine is difficult to start？

  Regarding the failure of the engine to start difficult, our troubleshooting directions are as follows.Troubleshoot points, Fuel injector failure, such as too small fuel injection at idle point;Sensor problems, such as water temperature sensor and intake air temperature sensor signal drift etc.

• Classification of fuel metering unit

  There are two types of fuel metering valves: normally open and normally closed. Pay special attention to them during maintenance. Due to the failure of the fuel system oil circuit itself, such as fuel quality, fuel pump wear and other reasons, the fuel metering valve wear or jam failure indirectly caused, when replacing the new fuel metering valve, the entire fuel system oil circuit must be checked at the same time , Clean and replace fuel that meets standards.

• How to use the decoder to read the fault code？

  The fault code is P1014,The flow rate in the fuel pressure relief valve exceeds the threshold value during reverse driving; The fault code is P0504,The signals of the brake main and auxiliary switches are not credible; P2299: The throttle and brake signals are not credible.

• Repair and maintenance of suction control valve

  Once the electronically controlled engine fails, the fuel injector and fuel metering unit will be replaced frequently. Among them, the suction control valve is often due to the valve body being worn and stuck, which often leads to failures such as difficulty in establishing rail pressure, difficulty in starting, intermittent flameout, and speed limit at 1500 rpm.

• Common faults and causes in common rail system

  In terms of machinery, if the oil system is not tightly sealed, it will be difficult to ignite if the air enters, or there will be flameout or vehicle movement when the middle of the fuel line is not clear. In terms of electricity, if the sensor is damaged, the engine will be weak, and it will be difficult to stop and start; if you can’t refuel, just look at the accelerator pedal; when welding, you must disconnect the computer version plug, and usually pay attention to maintenance to avoid the computer version. Corrosion of electronic components.

• What is suction control valve?

  The suction control valve (fuel inlet metering valve) is one of the most important components in the diesel engine fuel supply system, and it is the most important part of the throat.

• When suction control valve needs to be replaced？

  When your car has stalling issues, bad rough idling, huge RPM fluctuation problems, you have to consider that it may be the suction control valve(SCV) problem! The suction control valve is often overlooked when you are having issues with your vehicle.
