ABSTRACT:
A fuel injection control system for a two cycle crankcase compression internal combustion engine wherein two sensors are provided for sensing air flow by measuring different engine running conditions. One sensor has a greater accuracy in a certain range of operation than the other and the system primarily sets the fuel injection based upon the output of the more sensitive sensor for the running condition. In the event of failure of the more sensitive sensor, the system defaults to control by the other sensor. The system bases the control on average readings over a number of cycles and also senses fault by determining when a sensor outputs a number of erroneous signals that are greater than a predetermined percentage.
