Device for controlling the fuel starting mixture of an internal combustion engine

摘要

In starting or when idling a higher metered quantity of fuel is fed to an engine (51) by way of a carburettor (107) as a function of the determined operating values engine speed (N), intake air pressure (PA), engine coolant temperature (TC) and taking particular account of the intake air or ambient air temperature (TA) detected. The mixture prepared in this way has an air/fuel ratio precisely adjusted to the intake air temperature prevailing when starting, by means of which the cold starting characteristics of the engine are significantly improved at low ambient temperatures. <IMAGE>
