Abstract

Método de controle para uma válvula de pressão em excesso em um sistema de suprimento de combustível do tipo de trilho comum. Método de controle para uma válvula de pressão em excesso (12) em um sistema de suprimento de combustível de trilho comum (1), o método incluindo as etapas de: distribuir o combustível sob pressão, via uma bomba de alta pressão (6), a um trilho comum (5) equipado com a válvula de pressão em excesso (12) que é estabelecida para descarregar o combustível presente no trilho comum (5) em uma linha de descarga (11), quando a pressão do combustível dentro do trilho comum (5) excede um valor de segurança (psegurança); pilotagem, durante um teste de diagnóstico, da bomba de alta pressão (6) para aumentar a pressão do combustível dentro do trilho comum (5) além do valor de segurança (psegurança) com a finalidade de acionar a operação da válvula de pressão em excesso (12); determinação, durante o teste de diagnóstico, do fluxo (mHP) da bomba de alta pressão (6) e/ou da pressão do combustivel dentro do trilho comum (5); e comparação do fluxo (mHP) da bomba de alta pressão (6) e/ou pressão do combustível dentro do trilho comum (5) durante o teste de diagnóstico com os respectivos valores de limite (mteste e pteste).
