Product Overview
DB4427-6349 is a DB series 4-cylinder mechanical inline high-pressure fuel injection pump specially calibrated for NEF 4 NA 2V diesel engine, which serves as the core assembly of China II mechanical fuel supply system. It generates high injection pressure mechanically via four sets of precision plunger assemblies. The built-in full-range mechanical governor accurately controls fuel delivery volume, stable idle speed, overspeed fuel cut-off protection and injection advance angle. Optimized with increased fuel supply for long-term full-load heavy-duty operation of 4112ZLK engine, it delivers powerful low-speed torque and sufficient power reserve for full-load climbing, heavy starting and continuous intensive workloads.
Key Features & Benefits
- Mechanically pressurize diesel fuel for NEF 4 NA 2V engine
- Built-in mechanical governor guarantees steady idle speed and overspeed fuel cut-off safety lock
- Precisely adjust injection advance angle and fuel supply to maintain stable engine operation
