0445120082 Injector Assembly for construction machinery

0445120082 serves as a universal core common rail injection part for mainstream diesel engines. This general-purpose injector fits most heavy-duty diesel engines applied on heavy trucks, construction machinery and industrial power equipment. Adopting Bosch high-pressure common rail fuel technology, it provides ultra-fine fuel atomization and accurate fuel metering under variable load and continuous working conditions. It solves typical problems such as engine power drop, unstable idling, black smoke emission, hard cold start, slow acceleration and high fuel consumption. With fully consistent OEM parameters and strong universality, it supports direct original-position replacement without modification, ideal for general engine maintenance and overhaul.The precision-machined nozzle ensures uniform and fine fuel atomization for full cylinder combustion. The upgraded control valve improves injection timing and fuel metering accuracy, avoiding internal leakage and pressure loss. The reinforced structure withstands long-cycle high-pressure impact. Each finished injector passes strict high-pressure cycling tests, atomization inspection and dimensional calibration for direct replacement of old injectors.
