Control system and method for a bi-fuel engine
TLDR
In this paper, a control system for a bi-fuel engine with a powertrain controller and a Bi-fuel controller is described. But, the control system is limited to a single driver and each of the drivers can be used to generate a corresponding control signal for either a gasoline fuel injector 38 or an alternate fuel (AF), respectively.Abstract:
A control system 14 for a bi-fuel engine 12 Is provided. The control system 14 includes a powertrain controller 52 and a bi-fuel controller 54. The controller 52 has a set of fuel injector drivers 92. The controller 50 has a set of gasoline fuel injector drivers 104 and a set of alternate fuel (AF) fuel injector drivers 106. Each of drivers 92 in controller 52 is electrically connected to a driver 104 and a driver 106 in controller 50. Thus, a control signal generatea by a single driver 92 can be utilized by either of drivers 104, 106 to generate a corresponding control signal for controlling a gasoline fuel injector 38 or a AF fuel injector 40, respectively.read more
