Abstract

PROCESSO, E, SISTEMA DE DIAGNÓSTICO DE UM DESGASTE DE ÓLEO DE UM CONVERSOR DE TORQUE DE TRANSMISSÃO AUTOMÁTICA DE UM VEÍCULO AUTOMOTIVO. Este processo de diagnóstico de um desgaste de óleo (8) de um conversor de torque (1) de transmissão automática de um veículo automotivo comporta uma comparação das velocidades (Ômega M, Ômega T) do motor (2) e da turbina (7) do conversor de torque (1) quando o conversor de torque (1) do veículo estiver bloqueado.
