ABSTRACT:
A starting arrangement for a pressure-charged internal-combustion engine in which at the beginning of the starting phase combustion air is delivered to the engine by way of a bypass valve and a throttle valve in the charge-air line from the pressure-charging device is closed. Two mutually independent variables are used for controlling the opening of the throttle valve. At the end of the starting phase a command variable typical of the process e.g., charge air pressure is used to initiate an opening of the throttle valve and an engine-dependent operating variable e.g., engine lubricating oil pressure is then used to actually move the throttle valve to its open position, the throttle valve then remaining in the open position so long as the engine-dependent operating variable does not fall below a specified minimum value.
