摘要： An exhaust gas reflux device which is capable of accurately adjusting a valve opening to appropriately reflux an exhaust gas to a combustion chamber (1a) of a four cycle engine (1) for automobiles, even if the exhaust gas is a high temperature, high pressure exhaust gas from a diesel turbocar. In the exhaust gas reflux device (8), a movable shaft (23) is provided with two closure valves (19, 20) to allow an exhaust gas to flow into a movable space (10a) from within movable ranges of the two closure valves (19, 20). Accordingly, a high pressure of the exhaust gas constantly act on the two closure valves (19, 20) to be cancelled, and do not interfere with movements of the movable shaft (23), so that despite a high temperature, high pressure exhaust gas from a diesel turbocar, the movable shaft can be moved accurately by a small force of a stepping motor (17).

摘要： When a valve lift signal is received from a control unit (10), two of the coils (18a-18d) in a stepping motor (18) are energized to regulate the opening of the valve (14). A predetermined time after the completion of the opening regulation of the valve (14), the energization method for the stepping motor (18) is switched from a two-phase energization to a single-phase energization. This suppresses the generation of heat in the coil and the current consumption while the rotation is stopped.

摘要： A device for mounting an exhaust gas reflux valve and preventing a valve disc of an exhaust gas reflux valve which opens and closes an exhaust gas reflux passage in an engine and a stepping motor which drivingly and controlingly opens and closes the valve from being overheated by high temperature heat of an exhaust gas, wherein the valve body (201) of the exhaust gas reflux valve is embedded in that portion of an engine structure (100) where temperature is lower than exhaust gas temperatures. Thus the engine structure can absorb and spread high-temperature heat of the exhaust gas for radiation, and so it is possible to prevent overheating of the stepping motor (300) due to high-temperature heat of the exhaust gas without the need of any special water-cooled construction such as a cooling water chamber.
