PURPOSE:To reduce fuel costs and obviate an electric discharge, by setting up a device to intercept the feed of fuel without impairing car operatability as well as a device to control a continuous rating to load when a driver leaves his seat with an ignition switch turned on intact, to a fuel control apparatus. CONSTITUTION:When an engine is stopped with a fuel cut signal, a driver remains seated and a seat swtich 47 is still closed. When a signal of 1 from an engine R.P.M. deteting device 41 is inputted, a NOT circuit 40 makes its signal of 0 input into a transistor 43 so that excitation of a relay 44 is released and a normal-open contact 44a comes to open but as the switch 47 is still closed, a relay 84 still remains excited and a relay 81 is held by itself while a normal- open contact 81a remains closed, preserving a continuous rating to an electric load 48. When a car comes to a standstill after engine stopping, if driver leaves his seat with an ignition switch 45 on intact, the switch 47 comes to open and the relay 84 becomes unexcited, making a contact 84a open whereby the relay 81 also becomes unexcited and thereby the contact 81a comes to open; the continuous rating to the load 48 is thus cut off. |
