摘要： 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.

摘要： A deceleration control device is applied to an internal combustion engine having an air intake passage and a throttle valve disposed in the air intake passage. The device includes a fuel supply cut-off valve and a vacuum control valve. The cut-off valve selectively interrupts and recommences supply of fuel to the engine. The control valve conducts air to the air intake passage downstream of the throttle valve to weaken the vacuum in the air intake passage downstream of the throttle valve and suspends the conduction of the air. The device also includes a mechanism for causing the control valve to suspend the conduction of the air when the cut-off valve recommences supply of fuel.
