Diesel fuel track pressure sensor with stable output

Product description

High pressure common rail refers to a closed-loop mode composed of high pressure oil pump, Pressure Sensor and ECU(electronic control unit), which completely separates the generation of injection pressure from the injection process. The high pressure fuel is transported to the public oil supply pipeline through the high pressure oil pump. The precise control of the hydraulic pressure in the public oil supply pipeline can make the pressure of the high pressure oil pipe irrelevant to the engine speed, and greatly reduce the change of the diesel fuel supply pressure with the engine speed, which is the defect of the traditional diesel engine. The ECU controls the injection volume of the injector, which depends on the pressure of the fuel rail (shared fuel supply line) and the length of time the solenoid valve is open. By reducing the injection speed at the beginning of the main injection, the amount of oil injected into the cylinder during the ignition delay is reduced. Increasing the middle injection speed of the main injection can shorten the injection time and slow burning period, so that the combustion is completed in a more effective crankshaft Angle range, improve the power, reduce fuel consumption, reduce carbon smoke emissions. A quick cut-off at the end of the main injection reduces fuel emissions from incomplete combustion, reducing smoke and hydrocarbon emissions. Specializing in the manufacture of intake manifold absolute pressure sensor, Diesel Pressure Sensor, engineering hydraulic sensor, injection molding machine special pressure sensor.
