Nozzle typeZCK represents long multi-hole type, ZS represents axial needle type, ZK represents multi-hole type, etc.
➤
Spray angleRefers to the angle of the conical surface formed by the fuel sprayed by the nozzle. This angle determines the distribution range of the fuel in the combustion chamber and the mixing effect with the air.
➤
Needle valve body large end outer diameter sizeIndicated by letters, such as R corresponds to 16mm, S corresponds to 17mm, T corresponds to 22mm, etc. This size affects the matching installation of the nozzle and engine-related parts.
➤
Number of spray holes and spray hole diameterThe number of spray holes and the diameter jointly affect the injection speed, atomization effect and injection amount of the fuel. Generally, the more spray holes and the smaller the diameter, the better the fuel atomization.
➤
Injection pulse widthThe length of time the engine driving computer controls the injector to inject each time. The general pulse width range is between 1.5ms and 2.9ms.
➤
Solenoid coil resistance valueUsed to detect the status of the electromagnetic coil. Normal low resistance is about 2Ω-3Ω, high resistance is about 13Ω-16Ω.
➤
Working voltage and currentGeneral gasoline vehicle fuel injector working voltage is 12V. Ensuring correct voltage and current is vital to prevent nozzle distortion.
➤
Spray hole processing accuracySpray hole diameter is generally 0.08mm-2mm. High processing accuracy is required to ensure injection quality and reliability.
FAQ
1. What is the warranty period for this fuel injector?
The fuel injector comes with a 6-month warranty to ensure quality and reliability for our customers.
2. Is this fuel injector compatible with all diesel cars?
It is designed as a universal fitment for diesel cars, but please verify your specific engine code and model number (095000-6280 6219-11-3100) before purchasing.
3. What material is used in the construction of this injector?
This fuel injector is manufactured using high-quality stainless steel for durability and corrosion resistance.
4. How can I determine if my solenoid coil is faulty?
You can measure the resistance. An infinite value indicates an open circuit, while a value much lower than the standard (2Ω-3Ω or 13Ω-16Ω) may indicate a short circuit.
5. Why is the spray hole diameter important?
The spray hole diameter and count directly affect the fuel atomization effect, injection speed, and the overall mixing quality with air in the combustion chamber.
