Abstract
The utility model relates to an ignition advance angle regulator for clean fuel automobiles, which comprises a socket (CZ) for externally connecting, an SCM (N2), an output transformer (B), an electric relay (K), a first regulating switch (S1), a second regulating switch (S2) and a regulating resistance (R28). The utility model is installed on the automobile which uses gasoline and the clean fuel. After an ignition signal of an original automobile is converted through the SCM, the ignition signal is coupled through the output transformer and is output from an ignition signal output foot of the socket. When the automobile is switched to the operating state with the clean fuel and the automobile departs from a speed idling state, the ignition signal phase which is output by the SCM is advanced with an input ignition signal of the original automobile and the utility model achieves the purpose of changing the ignition advance angle. Four different advance angle values can be obtained by switching on or off the first regulating switch and the second regulating switch. When the automobile is switched to the operating state with the gasoline and the automobile stays in the speed idling state, the output ignition signal is the same as the input ignition signal of the original automobile.
