0445120029 A common-rail fuel injector developed specifically for use with Cummins QSL9 large-displacement heavy-duty engines. It features a high-current, waterproof dual-needle solenoid-driven solenoid valve. The engine’s ECU precisely controls the three-stage injection sequence—pre-injection, main injection, and post-injection—as well as the cyclic fuel injection volume, and is compatible with 1400–1800 bar high-pressure common-rail fuel systems. It utilizes the DLLA118P2203 high-flow, 8-hole vortex nozzle, which ensures thorough stratified atomization and combustion. Designed for 24-hour continuous heavy-duty operations in mining and construction applications, it complies with Euro 3 and US Tier 3 emissions standards.

6-month warranty. Damage caused by accidental impact, high-temperature scorching, rough disassembly or installation, or prolonged use of low-quality diesel fuel is not covered under the warranty.
