⚙️ Technical Insights
Because proper additive dosing is essential for emission regulation, the 044404228Z uses a precise gear mechanism to deliver exact fluid volumes per cycle. Also, Bosch engineers calibrate it to maintain steady flow even under low pressure. Furthermore, its design resists wear and clogging when using treated fluids like DEF. As a result, your exhaust system achieves better NOx reduction and fuel economy. In addition, the pump’s consistent output helps sensors and control systems work smoothly with other Cummins parts.
🛠 Application Scenarios
- Cummins diesel engines equipped with SCR systems needing accurate DEF dosing
- On-highway trucks that require reliable emission control additive delivery
- Construction and industrial equipment using active urea injection systems
- Stationary generator sets with chemical dosing for emission compliance
- Engine systems that depend on Bosch parts and Cummins parts for fluid metering precision
