| An emission control system including an auxiliary catalytic converter (50) coupled upstream of a main catalytic converter (44) via a bypass valve (52). Exhaust gas flow is first routed through the auxiliary converter (50) by opening one bypass valve (52) and closing another (48) when an indication of exhaust gas temperature is above a predetermined temperature.

| A failure determination device that detects the humidity of exhaust gases from an internal combustion engine and a control system for an exhaust passage changeover valve, which can switch the changeover valve with appropriate timing, thereby enabling sufficient purification of exhaust gases. An operating condition of the engine is detected. Based on the detected operating condition of the engine, it is determined whether the engine is in an operating condition in which failure determination of the humidity sensor can be executed. It is determined whether the humidity sensor has failed, based on a result of detection by the humidity sensor, when it has been judged that the failure determination of the humidity sensor can be executed. | ||||||

| A system for detecting malfunctions of an exhaust switch-over valve of an internal combustion engine, which opens/closes a bypass exhaust gas passage branched from an exhaust pipe of the engine and storing an adsorbent that adsorbs unburned components of the exhaust gas generated by the engine when the engine is started. In the system, the entrance temperature and the exit temperature in the bypass exhaust gas passage are detected and compared with each other in a first detection period when the passage is opened and in a second detection period when the passage is closed. Based on this comparison, it is determined whether the valve malfunctions. Alternatively, the valve malfunction is determined by comparing the valve opening/closing state with an instruction to operate the valve. With this, little time lag exists in the detection, thereby improving malfunction detection accuracy. | ||||||

| 18 | Failure diagnosis device for an EGR control system | US821063 | 1992-01-16 | US5207093A | 1993-05-04 | Mie Maeda |
| A failure diagnosis device for an EGR control system detects a predetermined running condition of the engine, and includes a control device which inputs values of predetermined parameters signifying the running condition of the engine at first predetermined times. The control device calculates differences between preceding input values and current input values, accumulates the differences, and opens the EGR path after determining that the EGR control system is normal, i.e. when the accumulated value reaches or exceeds a predetermined value after a second predetermined time has elapsed from when the EGR path is forcibly closed. The control device determines that the EGR control system has failed and generates an alarm when the accumulated value is below the predetermined value when the second predetermined time has elapsed. | ||||||
