DIESEL injector 0414702023 Solenoid valve assembly: Includes solenoid coil, armature, valve core, etc., responsible for receiving ECU signals to achieve rapid opening and closing.
Needle valve assembly: Precision-fitted needle valve and needle valve body, controlling the opening and closing of fuel injection.
Control piston and jet: Hydraulic servo system, controlling chamber pressure changes to achieve precise needle valve movement.
Injector: Multi-hole structure to ensure fuel atomization quality.
Sealing components: Includes O-rings, copper gaskets, etc., ensuring high-pressure sealing performance.
Working principle: When the ECU sends an injection pulse signal, the solenoid valve is energized, generating electromagnetic force to drive the valve core. Fuel in the control chamber is depressurized through the return channel, reducing the pressure above the control piston. The high-pressure fuel pushes the needle valve open, and fuel is injected from the injection orifice. After injection, the solenoid valve is de-energized, the valve core resets, the control chamber pressure returns to normal, and the needle valve closes rapidly under spring force and fuel pressure, stopping injection. The entire injection process is precisely controlled by the ECU to adjust the pulse width and timing, achieving precise fuel injection.
Technical Features
High-Pressure Injection Capability: Working pressure can reach over 1600 bar, ensuring complete fuel atomization.

FAQ
Q1: Which engine models is the 0414702023 injector compatible with?
A: This injector model is mainly compatible with some diesel engines from Volvo, Cummins, and Weichai brands, specifically Volvo D series, Cummins IS series, and Weichai WP series engines. Before actual application, it is necessary to verify the engine ECU calibration data and injector calibration code to ensure complete matching. It is recommended to refer to the original manufacturer's technical manual or consult a professional technician to confirm compatibility.
Q2: How to determine if this injector is working properly?
A: A preliminary assessment can be made using the following methods:
***Listen to the sound:** When the engine is running, use a stethoscope to touch the injector body. A clear "ticking" sound should be heard, with the frequency varying with engine speed.
***Measure the resistance:** Use a multimeter to measure the resistance of the solenoid coil. The normal value should be within the range of 0.2-0.3Ω.
***Observe the fuel return:** When the engine is running, a small amount of fuel should flow out of the return line (normal return flow ≤50ml/min).
***Professional testing:** Test parameters such as injection quantity, atomization quality, and opening pressure on an injector test bench.
Q3: What are the signs of poor injector atomization?
A: Typical symptoms of poor atomization include:
***Decreased engine power, weak acceleration**
***Black smoke from the exhaust pipe, especially noticeable during rapid acceleration**
***Unstable idling, engine vibration**
***Increased fuel consumption**
***Severe cases may be accompanied by "backfiring" or knocking sounds**
***Severe carbon buildup on the injector head**
