Denso original 095000-5321 Common Rail Fuel Injector for N04C Dyna200, Diesel Injector Nozzle 23670-78031 23670-79036 Construction Machinery original new injector

The DENSO 095000-5321 common rail fuel injector, OE 23670-E0140, is engineered for the HINO / Toyota N04C 4.0L diesel engine family, including N04C, N04C-TF, N04C-TQ, and N04C-TY variants. It is designed to fit HINO 300 Series, HINO Dutro 4500, Toyota Dyna, and Toyota Toyoace commercial vehicles, delivering factory-level fuel injection performance for light and medium-duty diesel applications. The injector provides high-pressure common rail atomization, accurate fuel metering, and stable injection timing, supporting clean combustion and consistent power output under demanding operating conditions.

Built to OE specifications with full part-number traceability across references 095000-5321, 095000-5320, 095000-5322, 23670-E0140, 23670-E0140B, 23670-78030, 23670-78031, and 23670-79036, this unit ensures direct-fit replacement and reliable interchangeability for workshops and distributors. Each injector is supplied in clean, distributor-friendly packaging to protect the precision internal components during storage and handling. Proper installation should include replacement of sealing washers, inspection of high-pressure lines, system priming, leak verification, diagnostic scanning, and injector coding when required by the engine control system.

Routine maintenance with clean diesel, regular fuel filter replacement, and periodic draining of the water separator are essential to maximize injector service life. When symptoms such as hard starting, rough idle, black or white smoke, diesel knock, power loss, excessive fuel consumption, misfire, fuel leakage, or rail pressure fault codes appear, technicians should perform leak-off testing, monitor rail pressure, evaluate injector correction values, conduct cylinder cut-out tests, verify electrical signals, and, if necessary, confirm performance on a test bench to identify and resolve injector-related issues.
