IN-LINE FUEL INJECTION EQUIPMENT - P SIZE MEFIN DESIGN

The P size in-line fuel injection equipment includes the following:

- injection pump (P-size, in-line) with its own camshaft, provided with a flange or base for mounting on the engine;

- feed pump, with single acting piston, hand-actuated pump and in some cases with   sediment bowl;

centrifugal speed governor RQ type, for two speed range or RQV for   all-range speeds

The in-line pumps follow the same basic operating principle and configuration, a pumping element and delivery valve for each engine cylinder, arranged in a straight line up to 12 cylinders.

The pump's plunger lift is constant and delivery per stroke is controlled by the timing of a metering helix on the plunger.

Fuel metering is adjusted to the engine speed by a mechanical governor. Each  size and individual pump within the size range is conceived, engineered and calibrated to meet the requirements of the specific engine for which it is intended.
