Abstract
PURPOSE: To reduce engine noise due to ignition lag, carrying out negative feed back control after the engine has been started, supplying usally optimum heating current to the preheater plug in accordance with temperature condition of the preheater plug.
CONSTITUTION: Prior to operation, when a relay switch 3 is shut by shutting the key switch 17 firstly, a heating coil 1a of the preheater plug 1 is energized, thereby air in the engine is heated. After that, with starting the engine, the speed becomes more than the prescrived value, the perfect combustion detecting circuit 19 becomes roll bell receiving the singal from the rotational freqeuncy sensor 20, the relay switch 3 is truned off. Simultaneously AC generator 7 is driven with the engine, the heating coil 1a is energized by its outout voltage. Subsequently when the electtical signal from the thermocouple 8 is increased, the field current of above generator 7 is controlled to reduce through the control circuit 9, consequently the temperature rise of the preheater plug 1 is suppressed
