ABSTRACT:
A fuel injection control system for a two cycle crankcase compression internal combustion engine that employs two sensors for sensing engine load. One of the sensor, a throttle valve position sensor, is more sensitive at low speed and low load conditions and the other of the sensor, a crankcase pressure sensor, is more sensitive under high speed and high load conditions. The output of the fuel injectors is controlled by a map ratio showing the input signals from the two sensors in response to their areas of greatest selectivity.
