Bosch original 300 350 360 Engine Fuel Injector 0445120236 4940170 Cross Reference Replacement for OEM 0986435554, 5263308 Suitable for Komatsu PC300 PC350 original new injector

Designed for electronically controlled, high-pressure fuel delivery, the BOSCH 0445120236 is an original new common rail fuel injector in the Bosch 120 Series. Manufactured to OEM standards, its solenoid-controlled design supports precise fuel metering, accurate injection and fine atomization. During operation, the ECU activates the injector solenoid, the control valve opens and the nozzle needle lifts, allowing pressurized diesel to be atomized through the multi-hole nozzle. The resulting air-fuel mixing supports combustion efficiency, emissions control, fuel economy, cold-start performance, torque output and overall engine efficiency.
An extensive cross-reference database covers Bosch replacement and exchange numbers plus Cummins, CNH and Komatsu references, including 5263308, 4940170, 84346812 and 6745-12-3100.

Equipment coverage extends to heavy-duty and commercial trucks, buses, excavators, loaders, road machinery, agricultural equipment, diesel generators, industrial power units and marine auxiliary engines, serving transportation, construction, agricultural and power-generation operations.
OEM quality, high-pressure operation, durability and extended service life support industrial reliability and reduced maintenance cost. Installation requires a new copper sealing washer, a clean injector seat, ECU coding verifiion where required, leak-off testing and a rail-pressure check. Preventive service includes OEM-grade fuel filters, clean diesel, regular water-separator draining and periodic ECU diagnostics. A 12-month warranty is specified.
