Abstract

PURPOSE: To enable with simple constitution, the stopping of fuel supply at troubling time on a flip flop frequency divider, by constituting safety timer, using a flip flop frequency divider which is used for setting of prepurge time and affirmed its operation.
CONSTITUTION: A timer 2 is consisted of T flip flop 3W7, and the T flip flop is set its output Q7 in "1" at reset input "1". As a memory circuit, an RSFF (RS flip flop) 10 is consisted of NAND gates 11 and 12 and holds prepurge finish signal of output Q7 in "0", as well contains a fuel supply device driving terminal 15 and an ignition device driving terminal 29. Furthermore an RSFF50 is consisted of NAND gates 51, 52 as a safety circuit and holds abnormal signal and non combustion signal. And abnormal signal input terminal 40 will turn in "1" at the time of abnormal and temp. signal input terminal 53 from temp. detection circuit will turn in "1" at low temp. time.
