Embodiment
Referring to figs. 1 through Fig. 3, the utility model is provided for the teaching case of automotive ignition system electric circuit teaching, comprise teaching casing, demonstrator is provided with in described teaching casing, described demonstrator is provided with conventional point ignition circuit, electronic igniting circuit, electronic control ignition circuit and power supply 1, the power supply 1 adopted is accumulator, and the circuit-line on above-mentioned demonstrator is dismountable line construction, and student can be allowed to understand the circuit theory of three kinds of firing circuits more intuitively.
Shown in Figure 1, above-mentioned conventional point ignition circuit comprises and connects the first ignition switch 2, first ignition coil 3, circuit breaker 4, first ignition distributor 5 and several spark plugs 6 successively, when circuit breaker 4 contacting, the flow direction of electric current is: the armature winding-circuit breaker 4 contacts-power supply 1 "-" of accumulator "+"-first ignition switch 2-the first ignition coil 3, primary current produces magnetic field in iron core.When the contact of circuit breaker 4 disconnects, primary current is cut off, magnetic field dissipate in iron core, the high-tension electricity kinetic potential of about 20000V is induced in the secondary winding of the first ignition coil 3, this electromotive force acts on spark plug 6, produce spark, by rotating the cam of the first ignition distributor 5, ignition order igniting pressed by each spark plug 6.
Shown in Figure 2, above-mentioned electronic igniting circuit comprises the second ignition switch 7, second point fire coil 8, second ignition distributor 9 and several spark plugs 6 that connect successively, the input end of described second point fire coil 8 connects the second ignition controller 10, the input end connection signal generator 11 of described second ignition controller 10, this signal generator 11 is hall signal generator.During work, the triggering impeller of driven by engine hall signal generator drives the shaft pulley of the second ignition distributor 9 to rotate, when the blade triggering impeller enters air-gap, signal generator 11 output HIGH voltage signal 11 ~ 12V, make the final stage large power triode conducting VT in the second ignition controller 10 integrated circuit, electronic igniting circuit is connected.When the blade triggering impeller leaves air-gap, signal generator 11 exports the low voltage signal of 0.3 ~ 0.4V, the large power triode of the second ignition controller 10 is ended, and circuit generation high-tension electricity (20000V-30000V) acts on spark plug 6 lights a fire.
Shown in Figure 3, above-mentioned electronic control ignition circuit comprises the sensor unit, the control unit of engine 12 that connect successively and is exported some igniting branch roads of connection by control unit of engine 12, and every bar igniting branch road comprises thirdly fiery controller 13, thirdly fire coil 14 and spark plug 6.
