A control method of a fuel feeding system in a bi-fuel internal combustion engine

摘要

A control method of a fuel feeding system (15) in a bi-fuel internal combustion engine (1); the feeding system (15) presents: a least a first injector (12a) adapted to inject a first fuel type; a least a second injector (12b) adapted to inject a second fuel type; a common electronic control unit (13) adapted to drive both injectors (12); and a switching device (14), which is controlled by the common electronic control unit (13) and is adapted to electrically connect both injectors (12) to the common electronic control unit (13) by means of at least a first relay (16a) adapted to connect/disconnect the first injector (12a) to/from the common electronic control unit (13) and by means of at least a second relay (16b) adapted to connect/disconnect the second injector (12b) to/from the common electronic control unit (13).
