Abstract
PURPOSE: To improve the engine-warming property at the time of starting operation thereof by a method wherein an amount of compensation of a complete combustion compensating mechanism opening a choke valve at a certain opening degree after complete combustion is lessened by a set value when the density of alcohol exceeds the set value in the engine wherein the mixture fuel of alcohol and gasoline is employed.
CONSTITUTION: The complete combustion compensating mechanism 6 puts the choke valve 2 in the state of full closure through the intermediary of a rod 7a before the complete combustion of the engine since the diaphragm 7b of a diaphragm device 7 is moved to the left by a spring 7e. After the complete combustion, it opens the choke valve 2 by a certain opening degree of compensation by the intake negative pressure introduced into a negative pressure passage 8 through the intermediary of the diaphragm device 7, whereby the compensation for the complete combustion is conducted. When the density of alcohol detected by an alconol density sensor 9 turns higher than a set value on the occasion, a solenoid valve 11 is operated by a control circuit 12 in a control device 10 to adjust properly the area of the opening of an opened-to-air port 8a, therewith the intake negative pressure is diluted and thus the value of the aforesaid compensation for the complete combustion is lessened.
