TW533267B - Auto choke control device - Google Patents

Abstract

To improve accuracy of controlling an auto choke without increased costs. When engine speed detected by an engine speed detection sensor 49 is equal to or greater than a set speed, using the microcomputer 46, the time that current is supplied to the PTC type auto choke heater 42 is controlled by pulse control of the transistor 47, and so it is not necessary to use the external resistor of the related art for adjusting voltage to an auto choke heater. Also, when such an auto choke is applied to engines with different characteristics, changing the on-pulse width of the microcomputer 46 according to the corresponding characteristics of engines can easily deal with such differences.
