Abstract

Este dispositivo de procesamiento de combustible evaporado se proporciona con: un pasaje (16) de combustible evaporado a través del cual un tanque (2) de combustible y un cartucho (3) se comunican entre sí; una válvula (21) de bloqueo que abre/cierra el pasaje (16) de combustible evaporado; un pasaje (19) de purga a través del cual el cartucho (3) y un pasaje (17) de admisión de un motor (1) de combustión interna se comunican entre sí; una primera válvula (23) de control de purga que abre/cierra el pasaje (19) de purga; una válvula (26) de corte de drenaje que cierra un pasaje (25) de drenaje; y una bomba (27) de presurización que presuriza el interior de un sistema. Cuando la diferencia entre la temperatura del combustible cuando se inicia una operación y la temperatura del combustible después de que termina la operación es al menos un valor de umbral, se realiza un diagnóstico de fuga al utilizar una presión positiva o una presión negativa existente en el tanque (2) de combustible; y cuando la diferencia entre las temperaturas del combustible es menor que el valor de umbral, se realiza un diagnóstico de fuga al utilizar la bomba (27) de presurización.
