  • the signal line 22 that communicates from the gasoline control unit 11 to the ignition device 5 is configured to go through the CNG control unit 51.
  • the signal lines 21 and 22 are divided by the CNG control unit 51.
  • the CNG control unit 51 cuts off the signal lines 21 and 22 during CNG operation, and stops the supply of gasoline and the ignition signal during gasoline operation.

  • the theoretical air-fuel ratio of natural gas is 17.2 when the representative molecule of hydrocarbon is CH 4 . Therefore, the stoichiometric air-fuel ratio of natural gas is leaner than the stoichiometric air-fuel ratio of gasoline. Therefore, for the same intake air amount, the basic injection pulse width Tp2 during CNG operation may be smaller than the basic injection pulse width Tp1 during gasoline operation.
  • the sensors 15 and 16 erroneously output that the air-fuel ratio of the exhaust gas is richer than the stoichiometric air-fuel ratio of gasoline during CNG operation. Therefore, the air-fuel ratio feedback correction coefficient ⁇ becomes smaller than 1.0 in order to return the air-fuel ratio of the exhaust to the lean side. As a result of calculating the air-fuel ratio learning value ⁇ m based on the feedback correction coefficient ⁇ , the air-fuel ratio learning value ⁇ m becomes smaller than 1.0. By calculating in this way, the air-fuel ratio learning value ⁇ m gradually becomes smaller than the value at the timing of t23.

However, the diagnostic parameter set based on the output of the sensor 15 is affected by the erroneous output of the sensor 15 during CNG operation. For this reason, even during CNG operation, in which the diagnostic parameter is affected by the erroneous output, if the sensor 15 is diagnosed as having failed or deteriorated based on the timer value T2, the diagnostic accuracy is lowered. .
  • the gasoline control unit 11 diagnoses that the sensor 16 has deteriorated because the period until the O 2 sensor output becomes zero when the fuel is cut during gasoline operation is equal to or greater than the threshold value A1.

Abstract

L'invention concerne un dispositif de diagnostic à deux combustibles comprenant : un dispositif d'alimentation en essence qui fournit de l'essence à un moteur ; un catalyseur pour purifier le gaz généré après la combustion de l'essence ; un capteur pour activer le catalyseur ; un dispositif d'alimentation en GNC qui liquéfie le GNC et fournit le GNC liquéfié au moteur ; un moyen de commutation de fonctionnement qui permet de basculer entre un fonctionnement à l'essence où le dispositif d'alimentation en essence est utilisé pour faire fonctionner le moteur et un fonctionnement au GNC où le dispositif d'alimentation en GNC est utilisé pour faire fonctionner le moteur ; un moyen de diagnostic qui effectue un diagnostic sur le capteur lui-même, et/ou utilise les valeurs fournies par le capteur pour effectuer un diagnostic sur le catalyseur, et/ou utilise les valeurs fournies par le capteur pour effectuer un diagnostic sur le système de post-traitement de l'échappement, pendant le fonctionnement à l'essence ; et un moyen d'arrêt de fonctionnement qui arrête le fonctionnement du moyen de diagnostic pendant le fonctionnement au GNC.
