Denso original Common Rail Fuel Injector 295050-0490 2950500490 Replacement for OEM 23670E0220 E13C Euro3 Diesel Engine Truck Parts original new injector

The DENSO 295050-0490 common rail diesel fuel injector is engineered for the HINO E13C 12.9-litre six-cylinder heavy-duty diesel engine used in HINO 700 Series and selected HINO 6 Series heavy truck applications, with market-dependent power variants of 321 kW, 331 kW, or 353 kW. Designed as an original-type replacement, it is matched against the authorized OE number 23670-E0220 and cross-referenced with 295050-0490, 295050-0491, 295050-0492, 095000-5223, and 095000-5970, giving buyers a reliable part-number link for E13C engine overhaul, workshop repair, and export parts supply where HINO E13C search demand is strong.

Built on DENSO common rail technology, the injector delivers precise fuel quantity at the correct timing, with ECU-controlled injection pressure, rate, and atomization to support lower emissions, improved fuel economy, reduced combustion noise, and stable high-load power output on heavy-duty operations. Each unit is bench-testable to verify spray pattern, opening pressure, and leak-free sealing, which is essential for E13C rail-pressure diagnosis and cylinder balance verification. Final fitment should always be confirmed by the original injector number, authorized OE number 23670-E0220, E13C engine code, and chassis or VIN before installation.

Reliable operation depends on clean fuel and a well-maintained common rail system, including regular fuel filter replacement, water separator service, fuel tank cleaning, and rail contamination control. Most early injector failures on HINO E13C engines are linked to contaminated diesel, water ingress, metal particles, incorrect coding, reused sealing washers, or a contaminated rail system, so professional installation, wiring inspection, ECU scanning, and aftertreatment diagnosis are recommended for long service life in demanding fleet and export applications.
