Commercial vehicle driven by an injection internal combustion engine having a transmission with hydrodynamic coupling or with a hydrodynamic torque converter

摘要

A commercial vehicle driven by an injection internal combustion engine with a transmission including a hydrodynamic coupling or hydrodynamic torque converter having a by-pass clutch and with an engine brake actuatable by way of a switch; an adjusting mechanism which is operatively connected with the controller of the injection pump includes an actuating cylinder containing an actuating piston adapted to be acted upon by a pressure medium and controllable in dependence on the engine brake; means which are provided for influencing the adjusting mechanism during the operation of the internal combustion engine, are interconnected between the engine brake switch and the adjusting mechanism and, upon disengagement of the by-pass clutch shortly prior to reaching the idling rotational speed of the internal combustion engine, effect an automatic adjustment of the controller of the injection pump from the zero fuel feed position to the idling position.
