发明名称 DEVICE FOR MEASURING AMOUNT OF FLOWING AIR IN INTERNALL COMBUSTION ENGINE
摘要 <p>PURPOSE:To measure the amount of sucking air precisely and speedily by a method wherein a non-linear signal output from a hot-wire circuit is converted into a linear one by a cumulative adding method. CONSTITUTION:The following signals are input to a control circuit 70; namely, a parallel digital signal input via a hot-wire circuit 80 in proportion to the speed of flowing air from a thermo-sensitive resistor 24 provided in an air passageway 22; a signal from an analogue input from a sensor 56 for checking engine-cooling water, from a lambda sensor 60 for detecting the state of exhausting gas in an exhaust pipe 10 and from an exhausting air temperature sensor not shown in the figure; a digital signal indicating diaphragm-opening degree of a diaphragm valve; and a pulse signal showing the standard clack angle. These signals are sent to the CPU to be processed in a digital calculation form, then a signal from the CPU is sent to an injector 12 and an ignition coil 58.</p>
