摘要:
A diagnostic system includes a first pressure monitoring module, a second pressure monitoring module, and a fault determination module. The first pressure monitoring module determines low-lift pressures and high-lift pressures in a cam phaser when a first oil control valve (OCV) moves first valve lifters to the low-lift state and the high-lift state, respectively. The second pressure monitoring module determines low-lift pressures and high-lift pressures in the cam phaser when a second OCV moves second valve lifters to the low-lift state and the high-lift state, respectively. The fault determination module diagnoses a fault in one of the first OCV and the second OCV based the low-lift pressures and the high-lift pressures.
摘要(中):
诊断系统包括第一压力监测模块,第二压力监测模块和故障确定模块。 当第一油控阀(OCV)分别将第一阀提升器移动到低提升状态和高升力状态时,第一压力监测模块确定凸轮相移器中的低升程压力和高升程压力。 第二压力监测模块确定当第二个OCV将第二个气门挺杆移动到低升力状态和高升力状态时,凸轮移相器中的低升程压力和高升程压力。 故障确定模块基于低升程压力和高升程压力来诊断第一OCV和第二OCV之一的故障。
