Abstract

DISPOSITIVO DE ALIMENTACION DE COMBUSTIBLES PARA UN MOTOR DE COMBUSTION INTERNA, EN EL QUE BAJO CONDICIONES DETERMINADAS, POR EJEMPLO, EN UN ARRANQUE EN CALIENTE, SE AUMENTA LA PRESION DEL COMBUSTIBLE, TENIENDO LUGAR ESTE AUMENTO DE LA PRESION MEDIANTE EL CIERRE DE UNA VALVULA DISPUESTA EN LA TUBERIA DE RETORNO DE COMBUSTIBLE Y HABIENDO ADICIONALMENTE UN ESTRANGULADOR EN PARALELO A LA VALVULA, O ESTANDO DISPUESTA UNA VALVULA DE SOBREPRESION ENTRE EL DISTRIBUIDOR Y EL DEPOSITO. LA ACTIVACION DE LAS VALVULAS, ASI COMO EL RECONOCIMIENTO DEL ARRANQUE EN CALIENTE, SE EFECTUA EN EL APARATO DE MANDO DEL MOTOR DE COMBUSTION INTERNA.FUEL SUPPLY DEVICE FOR AN INTERNAL COMBUSTION ENGINE, IN WHICH UNDER DETERMINED CONDITIONS, FOR EXAMPLE, IN A HOT START, THE PRESSURE OF THE FUEL IS INCREASED, HAVING TO BE PLACED THIS INCREASE IN PRESSURE DURING A SEVERE PRESSURE THROUGH A SEVERE PRESSURE. THE FUEL RETURN PIPING AND ADDITIONALLY HAVING A CHOKE PARALLEL TO THE VALVE, OR AN OVERPRESSURE VALVE BEING ARRANGED BETWEEN THE DISTRIBUTOR AND THE TANK. THE ACTIVATION OF THE VALVES, AS WELL AS THE RECOGNITION OF THE HOT START, IS EFFECTED IN THE CONTROL UNIT OF THE INTERNAL COMBUSTION ENGINE.
