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. |
