ABSTRACT:
In compact vehicle diesel engines, injection pumps are accessible only with difficulty for the purpose of adjusting a starting time of fuel delivery. An adjusting device is provided which includes an adjusting bolt or screw which may easily be reached from a top side of the engine. The adjusting bolt or screw includes a collar which is adapted to engage in a corresponding annular slot provided in an installation flange of a housing of the fuel-injection pump. A threaded portion of the adjusting bolt or screw is threadably accommodated in a threaded member pivotably fastened to the engine. When the adjusting bolt or screw is turned, the injection pump may be rotatably adjusted while a camshaft of the fuel-injection pump, connected to a timing drive of an internal combustion engine, remains in a previous position, thereby varying the start time of fuel delivery of the fuel-injection pump.
