20080209887 | EXHAUST THROTTLE VALVE DIAGNOSING DEVICE AND METHOD - When switching an exhaust throttle valve from full opening to a closed position to warm up an engine, an intake throttle valve is fixed to full opening, an EGR valve is fixed to full closing, and a variable turbo-vane is fixed to a predetermined opening degree to accelerate a gas flow rate from an intake passage to an exhaust passage, a fully opened flow rate is detected and stored by gas flow rate detection means, with the exhaust throttle valve being full opening, after which an instruction is issued to the exhaust throttle valve to switch from the full opening to a closed position for detecting a closed position flow rate, a flow rate difference is determined by deducting the detected closed position flow rate from the stored fully opened flow rate, and failure of the exhaust throttle valve is judged when the flow rate difference is less than a predetermined threshold value. | 09-04-2008 |
