The DENSO 095000-6593 is an authentic original-equipment G2 common rail diesel fuel injector engineered specifically for Hino J08E (6-cylinder, 7.7-liter, 197-209 kW / 264-280 hp) turbocharged electronically controlled diesel engines. Meeting EPA Tier 3 and EU Stage IIIA non-road industrial emissions standards, this injector is the primary combustion component deployed across Kobelco SK330-8, SK350-8, SK350LC-8, and SK380D-8 heavy hydraulic crawler excavators and Hino 500 Series Ranger heavy commercial trucks. Operating at rail pressures up to 1800 bar (26,100 psi) supplied by Denso HP3/HP4 high-pressure fuel pumps, this injector incorporates a calibrated DLLA155P868 multi-hole nozzle (Denso part number 093400-8680) and a hardened Plate 10# electro-hydraulic spool control valve to achieve precise micro-pilot, main, and split post-injection cycles. Denso part number 095000-6593 supersedes previous production revisions 095000-6590, 095000-6591, and 095000-6592, and corresponds directly to Hino OEM references 23670-E0180 through 23670-E0185 and Kobelco construction machinery reference VH23670E0180.
CRITICAL WORKSHOP NOTICE: Always photograph or manually record the 30-digit Denso QR Compensation Code laser-etched onto the injector solenoid cap BEFORE installation. Once the injector is seated in the cylinder head, this calibration code cannot be read. Denso 095000-6593 (Hino OEM 23670-E0180 / Kobelco VH23670E0180) is the flagship electro-hydraulic G2 common rail injector powering Hino J08E (7.7L 6-cylinder) Tier 3 / Stage IIIA diesel engines in Kobelco SK330-8, SK350-8, and SK380D-8 hydraulic excavators. Tighten the injector hold-down clamp bolt to 30 N·m (22 lb·ft) and the high-pressure fuel feed line nut to 30 N·m (22 lb·ft). Writing the 30-digit QR code into the engine ECM via Hino DX, Hino e-Doctor, or Kobelco diagnostic software is mandatory to avoid severe idle vibration, cylinder contribution imbalances, and black smoke under hydraulic load. CAUTION: Never mix 095000-6593 with 095000-6353 (Hino 23670-E0050) as nozzle flow ratings and injection delivery maps differ significantly.

Installation Tips
Tools needed: Calibrated torque wrench (10-60 N·m range), Hino DX / Hino e-Doctor or Kobelco diagnostic scan tool with J2534 VCI, Denso QR code reader or high-resolution smartphone camera, Injector bore reamer and copper seat cleaning brush kit, Lint-free industrial cleaning swabs, Clean engine oil or assembly lubricant for O-rings, High-pressure fuel injection pipe socket (17 mm flare nut wrench), Compressed air line with rubber nozzle
Diagnostic Trouble Codes & Fault Protocols
Common diagnostic trouble codes (DTCs) triggered when this common rail injector experiences wear, circuit faults, or calibration drift:
Fuel Rail / System Pressure Too Low
Excessive internal backleak from worn control valve seats drops common rail pressure below target under engine load.
Injector Circuit Malfunction / Open Circuit
Solenoid coil resistance drift (0.2-0.5 Ω) or piezo stack degradation triggers driver stage shutdown on affected cylinders.
Cylinder Misfire & Balancing Deviation
Carbon-clogged nozzle spray holes or missing IMA calibration causes uneven cylinder contribution. Recode ECM and verify washer seating.
Fuel Rail / System Pressure Too High
Spill line backpressure or stuck metering valve prevents rail depressurization, creating overpressure risks under load.
