Denso 295050-0971 Common Rail Fuel Injector

The Denso 295050-0971 is a high-pressure common rail diesel fuel injector designed for the Isuzu 4LE2 engine platform. It utilizes a solenoid-actuated multi-hole nozzle (G3S63) to deliver precise fuel metering and atomization under operating pressures up to 1800 bar. The injector body is constructed from high-strength alloy steel with hardened internal components to withstand continuous high-cycle fatigue in construction machinery duty cycles. This unit serves as a direct OEM replacement for Isuzu part numbers 8-98163524-1, 8-98163524-0, and 8981635241. It is calibrated to match the original engine ECU injection maps for the 4LE2 engine without requiring recoding. Primary applications include Kobelco SK75SR (Acera) and Case CX75C SR, CX80C hydraulic excavators. Each injector undergoes flow testing at multiple pulse widths to verify spray pattern, leakage, and back-leakage rates against OEM specifications.
