ABSTRACT:
A solenoid operated valve is positioned in the idle fuel mixture passage of the carburetor of an internal combustion engine of an automobile. When the automobile has reached a certain speed, if the driver releases the accelerator, a throttle linkage switch will close. Also, a vacuum sensing device will cause another switch to close thereby activating the solenoid valve to interrupt fuel flow through the idle fuel mixture passage. Thereafter, the solenoid valve will remain closed until the speed of the engine has decreased to a predetermined speed as measured by the amount of vacuum created by the engine. When the speed of the engine has decreased to the predetermined speed, or upon pushing the accelerator pedal, the solenoid valve will open again following fuel to flow through the idle fuel mixture passage. Upon turning the ignition switch OFF, the solenoid valve in the idle fuel mixture passage is closed to prevent dieselizing of the engine.
