Denso original 295050-1590 Common Rail Fuel Injector for Hino P11 Truck Excavator Diesel Injector Nozzle Replacement for OEM 23670-E0590 23670-E0600 original new injector

The DENSO 295050-1590 common rail diesel fuel injector is engineered as an OE-type replacement for the HINO 11 Series catalog, covering the HINO P11 and HINO P11C diesel engines widely used in HINO buses, trucks, and commercial diesel applications. It carries the main OE number 23670-E0590, along with cross references 295050-1590, 2950501590, 295050 1590, 23670E0590, and 23670 E0590, supporting number-rich search coverage across global spare parts distribution channels. An additional supplier-listed search application covers the Isuzu 6WG1-TC, which should be verified before shipment.

Built on DENSO common rail design, this injector delivers precision fuel metering and accurate spray atomization through ECU-controlled injection, ensuring stable combustion, consistent power output, and improved fuel economy under heavy-duty operation. The OE-style replacement construction allows direct fitment into the HINO P11 / P11C engine platform, supporting common rail fuel system overhaul, engine repair, and injector replacement tasks for fleet maintenance operations. Test bench compatibility further supports pre-installation inspection, full-set balance checking, and injector code recording.

Reliable long-term performance requires clean diesel fuel, scheduled fuel filter replacement, regular water separator draining, and fuel tank cleaning when contamination is identified. Routine inspection of fuel pipes, the high-pressure pump, and return flow should be performed, together with ECU data monitoring and spray pattern testing. Common failure symptoms such as hard starting, rough idle, white or black smoke, power loss, high fuel consumption, and abnormal injector correction values indicate the need for return flow testing, rail pressure monitoring, cylinder cut-out testing, and full fuel system contamination inspection. Shorter service intervals are recommended in regions with lower fuel quality, and additional monitoring is advised for high-mileage or heavy-duty operation.
