The Robert Bosch In-Line Injection Pump (Type “P”) for Diesel Engines - Further Development of a Proven Line of Injection Pumps 780770

The Robert Bosch series of In-Line Pumps currently serves engine output requirements ranging from 13 to 268 BHP per cylinder. In this family of injection pumps, the type P in-line pump is mainly applied to heavy-duty, direct injected truck engines, with power output up to 80 BHP per cylinder.

Since 1962 approximately 1.5 million pumps of this type have been supplied to the field.

Advanced development of the Diesel engine aimed toward increased power output and more favorable exhaust emissions have made further development of the injection system necessary. Conversely, however, the continued development of the injection system provides the possibility of realizing these improvements to the engine.

As a contribution to this development, Robert Bosch has redesigned the “P” pump.
