Abstract
PURPOSE: To improve idle running character in an engine using mixture fuel by providing an alcohol concentration senser and a control device of throttle opening angle, in which the throttle opening angle is opened as much as the predesignated value to increase the feeding fuel in case of the alcohol concentration being found higher than the designated value.
CONSTITUTION: A fuel feeder device feeding fuel mixed with alcohol and gasoline, is additionally provided with a control device of throttle opening angle, which comprises an alcohol concentration senser 10 composed of a condenser, a controller 11 controlling the opening angle of a throttle valve 3 and being operable with response to the output of the concentration senser 10, 3 ways valve 8 and still a diaphragm type controller 4. If the alcohol concentration of mixture fuel F detected by the concentration senser 10 is excessive than the designated value of the controlle 11, the 3 ways valve 8 is opened so as to link a negative pressure room 6 with a suction passage 1. In such a idle running time, suction negative pressure is led into the back room 6 to displace the diaphragm 4a for opening a throttle valve 3 as much as the designated value through a rod 5 so that the mixture fuel is increased. Resultantly running character is improved.
