Description

1. This 1112-00177 Fuel Injector Component is an OEM-calibrated critical part for the high-pressure fuel injection systems of King Long, Higer, Zhongtong, and Golden Dragon buses, widely fitted to Yuchai, Weichai diesel engines common in transit fleets. It is engineered to deliver precise fuel atomization, optimal combustion efficiency, and reliable power output under heavy-duty operating conditions.
2. Constructed with high-grade stainless steel and heat-resistant copper alloy, the component features a precision-machined nozzle tip and a corrosion-resistant fuel inlet connector. Its robust build withstands extreme cylinder temperatures, high fuel pressure, and the rigors of dusty, off-road environments, preventing clogging and extending service life.
3. Undergoes strict flow-rate calibration and spray-pattern testing to match OEM specifications, ensuring consistent fuel delivery across all cylinders. This balance eliminates rough idling, reduces fuel consumption, and lowers harmful emissions—critical for fleet compliance and operational cost control.
4. Designed for direct plug-and-play installation, it perfectly matches the original fuel rail and wiring harness without requiring ECU reprogramming or modifications. This design drastically cuts down maintenance time and labor costs for bus depots and repair workshops.
5. Delivered as a brand-new, factory-sealed component, it is compatible with both mechanical and common-rail fuel systems (verify engine model for exact fit). Each unit ensures long-term performance and minimal downtime for your bus fleet.
