ISUZU 4HK1 / 6HK1 Fuel Injector - OEM
Common Rail fuel injector, designed for ISUZU 4HK1 and 6HK1 series diesel power units. This is a precision electromechanical component responsible for metering fuel under extremely high pressure directly into the combustion chamber. As an OEM quality product, the injector guarantees ideal fuel atomization parameters to maintain emission standards and optimal fuel consumption.
Product Specifications and Features:
- Application: ISUZU 4-cylinder (4HK1) and 6-cylinder (6HK1) engines used in excavators (JCB, Hitachi, Case, Sumitomo) and ISUZU N and F series trucks.
- System: Common Rail (high-pressure direct injection).
- Precision: Multi-hole nozzle tip manufactured using laser technology to ensure consistent fuel dosing.
Technical Advice: 4HK1/6HK1 injectors are extremely sensitive to contaminants in the fuel system. Every time injectors are replaced, it is mandatory to replace the fuel filters with original ones and check the cleanliness of the fuel tank. After installing new injectors, it is necessary to code them into the Engine Control Unit (ECU) using a diagnostic tool (entering QR/IMA codes) to ensure balanced cylinder operation and prevent excessive smoking.
