Abstract
In an electronic fuel injection system for an internal combustion engine, a vacuum switch and a throttle valve switch respectively monitor the intake manifold pressure and the opening of the throttle valve. Fuel enrichment is achieved in response to these two switches in such a manner that the fuel enrichment is performed even in the case of low speed and relatively high load engine operating conditions, as well as at full throttle. In such a low speed, relatively high load range, the amount of fuel enrichment may be less than at full throttle. Optionally the fuel enrichment is achieved only by the vacuum switch without the throttle switch. The vacuum switch optionally has an altitude compensation mechanism.
