Thus, although the mechanical plunger pump has a fixed stroke, electronic control can select any part of that stroke to deliver to the cylinder, thereby controlling the volume and timing of fuel delivery.
22.
In power applications where continuous duty plunger pumps are needed, solid ceramic plungers may be used when in contact with water and oil, but may not be compatible for use with highly acidic media types.
23.
The overall capacity of the piston pumps and plunger pumps can be calculated with the area of the piston or plunger, the stroke length, the number of pistons or plungers and the speed of the drive.
