Product Overview

DB4427-5971 is a mechanical inline high-pressure fuel injection pump specially fitted for 4 NA 2V diesel engine, the core component of China II mechanical fuel system. It generates injection pressure through four sets of precision plunger assemblies. The built-in mechanical governor accurately controls fuel delivery volume, stable idle speed, over-speed fuel cut-off and injection advance angle, ensuring strong low-speed torque for turbocharged engines under climbing and heavy-load conditions.
