4940170 is a replacement fuel injector designed for Cummins QSL9 and Komatsu 6D114E heavy-duty mining engines. It features a high-current, waterproof dual-needle solenoid valve and is precisely controlled by the vehicle’s ECU to deliver three-stage fuel injection—pre-injection, main injection, and post-injection—and is compatible with high-pressure rail pressures of 1400–1800 bar. Equipped with an 8-hole high-flow swirl nozzle, it ensures thorough stratified atomization and combustion, meeting the demands of 24-hour continuous heavy-duty mining operations and complying 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.
