Abstract
A device for increasing an amount of fuel to be supplied to an engine includes a fuel increasing mechanism for supplying an added amount of fuel to the engine, and an electric control circuit including a low-temperature sensor for detecting a low temperature of the engine to produce a first signal capable of actuating the fuel increasing mechanism, and a neutral-gear-condition detector for detecting the neutral-gear-condition of a gear transmission associated with the engine to produce a second signal. The fuel increasing mechanism is inactivated in response to the second signal from the neutral-gear-condition sensor by overriding the low-temperature sensor to prevent the increase of fuel while the gear transmission is in neutral. A second embodiment employs additional sensors for air temperature, engine r.p.m., vehicle speed and the park-condition of an automatic transmission also for controlling the fuel increase.
