• Isuzu suction control valve

  Because the engine ECU controls the injection system including injection pressure, injection rate and injection timing, it is not affected by engine speed or load. This can ensure that a stable injection pressure is always maintained, especially in the low engine speed range, and can greatly reduce the amount of black smoke usually emitted by diesel engines during start-up and acceleration. Therefore, exhaust emissions are cleaner and reduced, and a higher power output is achieved.

• Diesel engine fuel metering unit inspection

  Diesel engine fuel metering unit inspectionAfter the fuel metering unit is disassembled, it is mainly composed of the following parts. The electromagnetic coil is integrated into the shell. Front iron gasket. case. Piston, spring, adjusting washer.There are two types of fuel metering units: normally

• Ten sensors and solenoid valves on the engine

  For the sake of environmental protection, most excavators are now electronic fuel injection vehicles. We often encounter various alarm codes, and these alarms are mostly caused by sensor or solenoid valve failure. The following are the positions and functions of ten sensors and solenoid valves on the engine. When an alarm code appears on the excavator and the meaning of the code is understood, it can be checked and replaced according to the position of the sensor and solenoid valve.

• High/Low Pressure Oli Passage of the Engine（IMV）

  High/Low Pressure Oli Passage of the Engine（IMV）, Adjust the opening of the valve to control the amount of fuel flowing into the high-pressure fuel pump. When the control signal is not applied, the amount of fuel in the high-pressure fuel pump is the largest.

• What does the suction control valve actually do?

  Technicians need to understand fuel rail pressure control on common rail diesel (CRD). In order to operate efficiently on common rail diesel (CRD), the correct fuel pressure must be maintained under all driving and load conditions. To do this, use the intake control valve (SCV) or fuel metering control valve (FMCV) operated by the ECU located on the back of the high-pressure fuel pump.

• How to deal with pressure limiting valve failure？

  Common rail pressure limiting valve opening failure is one of the most common failures in diesel vehicles. Once the common rail pressure limiting valve opening failure occurs, the engine will enter the limp function. The engine limits the torque.

• How to remove and install the fuel injection pressure sensor？

  Full explanation what is a fuel pressure sensor, working principle of the fuel pressure sensor, installation method, how to troubleshoot and detect the fuel pressure sensor failure. The fuel pressure sensor is also called a fuel pressure regulator, which is used to control the fuel pressure in the fuel circuit, maintain a constant fuel supply pressure from the fuel injector, and send excess fuel back to the fuel tank. Fuel pressure sensors are divided into high pressure fuel sensors and low pressure fuel sensors.

• The role of common rail pressure sensor

  Common rail pressure sensor is one of the important components of the diesel engine fuel system. A sensor is used to measure the pressure in the fuel rail and provide electrical signals to the electronic control unit.

• Why is precise machinery so hard to manufacture?

  Why is precise machinery so hard to manufacture? Because the production of any precision machinery cannot be produced 100% without error, just as humans cannot produce an absolutely smooth and frictionless surface.
