The car electronic fuel-saving device (2)
The principle of the circuit The car electronic fuel-saving device is composed of the diodes VD1-VD6, the resistors R1-R8, the capacitors C1 and C2, the transistors V1-V3 and the electromagnetic valve YV, the circuit is as shown in figure 7-140. Components selection R1-R8 are the 1/4W metal film resistors or the carbon film resistors.C1 and C2 are the 16V aluminum electrolytic capacitor.VD1-VD6 are the 1N4007 silicon rectifier diode.V1 and V3 are the S8050 NPN transistors; V2 uses the DDO3 silicon NPN transistor.YU uses the 12V DC electromagnetic valve.
