description

295050-1520/8630 common rail injector is the core fuel injection control component of construction machinery diesel engine. It precisely controls injection timing, cyclic fuel quantity, injection rate and atomization quality under high common rail pressure. The injector body adopts high-strength alloy steel. Core parts including G3S nozzle, needle valve and control valve are strictly screened and ultra-precisely machined with micron-level clearance control. Every finished injector undergoes full item bench testing covering idle, full load, pre-injection and leakage inspection, guaranteeing outstanding injection consistency and interchangeability. Direct fit replacement without mechanical modification. Suitable for construction machinery working on earthmoving and quarry sites with frequent load variation. It effectively resolves typical engine faults such as insufficient power, rough idle, black smoke and high fuel consumption, meeting maintenance and overhaul demands for construction machinery powertrain.

advantage

• High-precision matched internal components. The injector body is forged from high strength alloy steel. Core needle valve, G3S nozzle and control valve are carefully selected, processed to micron tolerance. It resists dripping, internal and external oil leakage under continuous high pressure, keeps injection action sensitive and stable, reduces stuck valve risks.
• Professional bench calibration & full inspection. Every injector is calibrated and tested on professional common rail bench. Test items cover idle flow, full load flow, pre-injection precision, opening pressure and return oil volume. Small injection deviation between individual injectors, excellent batch consistency, avoiding uneven fuel supply problems.
• Optimized G3S atomization structure. The precision nozzle creates fine and uniform mist. Diesel mixes sufficiently with air inside cylinder. Combustion efficiency is greatly improved. It maintains stable power output under heavy intermittent load, cuts black smoke and reduces harmful exhaust emissions.
• Strong adaptability for harsh construction site conditions. Designed for Isuzu 4HK1/6HK1 construction machinery diesel engine, fit for excavation, earthmoving and quarry worksites, coping with frequent start-stop and sudden load changes. Stable performance under wide temperature range. Better tolerance to low-quality site diesel, lowering premature failure caused by impurity abrasion.
• Upgraded composite sealing design. Multiple sealing surfaces are optimized to prevent fuel seepage. It helps eliminate common faults like rough idle, slow flameout, carbon accumulation and engine shaking, extending service life of injector assembly.

FAQ 

Q1: Can this injector fit all construction machinery engines?
A1: No. Model 295050-1520 / 8630 injector is dedicated for Isuzu 4HK1 / 6HK1 diesel engine, matching OE number 8-98139816-3 or 8-98243863-0. Before ordering, please verify engine model and old injector OE code. Wrong part will lead to weak power, heavy black smoke, rough idle and even engine mechanical damage.

Q2: What testing will be carried out before shipment?
A2: All injectors are 100% fully tested on professional common rail test bench before delivery. The test scope includes idle injection quantity, full-load injection quantity, opening pressure and static sealing leakage test. Products can only be packed after all indicators meet standards.

Q3: What is the warranty policy and what damage is excluded?
A3: 12-month warranty under correct installation and normal operation. Warranty does NOT cover damage caused by inferior dirty diesel, water mixed into fuel, fuel filter not replaced on schedule, wrong installation torque, unauthorized disassembly of internal parts, engine mechanical failure or man-made damage.
