- 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.KNOWLEDGE September 30, 2020
- Classification of fuel metering unitThere 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.KNOWLEDGE September 23, 2020
- 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.KNOWLEDGE September 16, 2020
- Repair and maintenance of suction control valveOnce 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.KNOWLEDGE September 10, 2020
- Common faults and causes in common rail systemIn 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.KNOWLEDGE September 06, 2020
- 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.KNOWLEDGE August 25, 2020
- 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.KNOWLEDGE August 21, 2020
- Operating principle of control valveThe most common final control element in the process control industry is the control valve. Control valves operate the flow of a fluid, such as gas, steam, water, or chemical compound, to compensate for load disturbances and to bring the adjusted process variables as close as possible to the desireBLOG April 21, 2020
- What is a control valve?Control valves automatically regulate pressure and/or flow and can be used for any pressure. If different equipment systems are operating at the required pressure/temperature combination of the 300 level valve, and sometimes (where the design permits) all selected control valves will have 300 levelBLOG April 21, 2020
- Working principle of fuel metering unitWhat is a fuel metering unit? Take BOSCH as an example, fuel metering unit is also known as feed metering proportional valve. It is installed in the inlet position of the high-pressure oil pump and used to adjust the fuel supply and fuel pressure value, which is controlled by the ECU computer.Fuel mBLOG April 21, 2020
