Description

 

How the fuel injection pump works
Oil suction process: The plunger is driven by the cam of the camshaft. When the convex part of the cam leaves the plunger, the plunger moves down under the action of the plunger spring, the volume of the oil chamber increases, and the pressure decreases; When the radial oil inlet hole of the pump is exposed, the fuel in the low pressure oil chamber flows into the pump chamber along the oil inlet hole.
Pumping process: when the convex part of the cam pushes the plunger up, the volume in the pump cavity decreases, the pressure increases, and the fuel flows back to the low-pressure oil cavity along the radial oil hole on the plunger sleeve; when the plunger When the radial oil hole on the plunger sleeve is completely blocked, the pressure on the pump chamber increases rapidly; when the pressure overcomes the preload of the oil outlet valve spring, the oil outlet valve moves up; When the pressure relief ring of the valve leaves the valve seat, the high-pressure diesel oil is pumped into the high-pressure oil pipe and injected into the cylinder through the injector.
The working principle of the plunger pump
The working principle of the plunger pump [1]
Oil return process: As the plunger continues to move upward, when the chute on the plunger communies with the radial oil hole on the plunger sleeve, the fuel in the pump cavity passes through the axial oil passage on the plunger, obliquely. The oil passage and the oil hole on the plunger sleeve flow back to the low pressure oil chamber, and the pump oil stops.
