• Specification

• Function

1.Pressurization: Converts low-pressure fuel (from the tank/filter) into high-pressure fuel—critical for atomizing fuel in the combustion chamber (weak pressure causes misfires or low power).

2.Timed Delivery: Uses a gear connection to the engine crankshaft to inject fuel exactly when the piston reaches the compression stroke, optimizing combustion efficiency and reducing unburned fuel.

3.Load-Based Regulation: A built-in mechanical governor adjusts fuel flow based on engine load (e.g., more fuel for heavy digging, less for idle), preventing over-fueling or under-fueling.
