EQUIPO PARA EL CONTROL AUTOMATICO, DEPENDIENTE DE LA CARGA, DEL AVANCE DE ENCENDIDO PARA MOTORES DE GASOLINA, DE CUATRO TIEMPOS

摘要

The system comprises a pair of relays J1, J2 which control the connection to an ignition unit M of a respective one of two contact breakers M1, M2 thereby advancing or retarding the ignition timing in dependence on the position of the throttle. When the throttle is depressed, an earthed switch K engages a movable contact K2 to energise the relay J2 and enable one of the contact breakers M1 or M2 to be connected to the ignition unit. Similarly, if the throttle pedal is released, the other relay is energised via contact K1 to connect the other contact breaker to the ignition unit.
