21379931 belongs to Del-phi heavy-duty cam-driven EUI unit injector lineup, custom engineered for Vol-vo Penta 13-liter power units that run continuously for days on marine vessels, stationary generators and off-road mining equipment. This integrated assembly combines built-in high-pressure spring booster, multi-hole precision nozzle and high-speed electromagnetic solenoid, eliminating the need for shared common rail pipelines. It effectively resolves recurring fuel system faults including nozzle carbon buildup, solenoid signal lag, internal pressure leakage and engine power derate, widely stocked by marine repair yards and global mining machinery spare parts distributors.
Mining Construction Gear: Vol-vo A25G, A30G articulated dump haulers, mine site fixed power supplies
Distinctive Product Core Advantages
Multi-Scenario Continuous Load Calibration
All injectors are tuned under low-speed steady load curves matching marine navigation, generator standby and mining heavy haul working modes, maintaining stable injection volume during non-stop operation without power fluctuation or unstable generator voltage output.
Stainless steel nozzle needle and anti-rust coated compression spring assembly, specially optimized for humid marine salt air and dusty damp mine workshop environments, greatly extend service life for watercraft and mining power equipment.
Low-Drift Fast Response Solenoid Valve
Original-spec beige plastic electrical connector with stable signal transmission, supports multi-stage pre-main injection to smooth low-RPM combustion, eliminate harsh engine vibration and loud knocking noise under light idle load.
Ultra-Fine Multi-Hole Atomization Nozzle Design
Micro tiny nozzle holes achieve uniform fuel atomization, drastically cut black smoke emissions and lower daily fuel cost for long-hour continuous operation, fully compliant with mainstream marine and industrial emission standards.
1:1 OEM Direct Drop-In Installation
Identical overall length, spring assembly size, sealing O-rings and wiring connector as original factory injector, no pipeline modification or ECU reprogramming required during replacement to cut maintenance downtime.
Common Engine Malfunctions This Injector Fixes
Hard cold startup, prolonged cranking without stable ignition for standby generators in cold weather
Single cylinder misfire, violent engine shaking and abnormal exhaust noise under light idle load
Severe power shortage during full-load power generation and full-speed marine navigation/mining hauling
Thick black exhaust smoke and obvious daily fuel consumption rise for long-running equipment
Fuel seepage between injector body and cylinder head mounting sealing surface
MOQ: 1 Piece, ready stock, shipped within 1–3 working days
