    摘要： An HC adsorbent which adsorbs hydrocarbons in a predetermined low temperature region and discharges hydrocarbons in a temperature region higher than the lower temperature region is provided in an engine exhaust passage. A catalyst which oxidizes hydrocarbons in a predetermined high temperature region is provided downstream of the HC adsorbent. A heater for heating exhaust is provided upstream of the HC adsorbent. A control unit activates the heater when the exhaust temperature has risen to near the upper limit of the lower temperature region. Activation of the catalyst is thereby promoted, and the time until the catalyst starts oxidizing hydrocarbons discharged by the HC adsorbent is shortened.

    摘要： A system for shaking water off a surface includes an electromagnetically operable driver unit for driving a member having the surface. The driver unit is connected to a control unit which controls oscillation frequency to be generated by the driver unit. The control unit adjusts the frequency of oscillation transmitted to the member for matching the oscillation frequency with the resonating frequency of the member for effectively shaking the water off the surface.

    摘要： An exhaust gas purifying system for an automotive internal combustion engine includes a NOx treating catalyst for reducing NOx disposed in an exhaust gas passageway of a combustion device, to reduce NOx in presence of reducing components in exhaust gas. Additionally, a hydrogen enriching device is disposed upstream of said NOx treating catalyst with respect to flow of exhaust gas from the combustion device and arranged to increase a ratio of hydrogen to total reducing components in at least one of combustion gas and exhaust gas so as to meet relations represented by following formulae (1) and (2), when reduction of NOx is carried out by the NOx treating catalyst: [H2/TR]d>[H2/TR]u  (1) [H2/TR]d≧0.3  (2) where [H2/TR]u is a ratio between a concentration [H2]u of hydrogen and a concentration [TR]u of total reducing components in at least one of exhaust gas in the exhaust gas passageway upstream of the hydrogen enriching device and combustion gas in a state before undergoing the hydrogen ratio increasing by said hydrogen enriching means; and [H2/TR]d is a ratio between a concentration [H2]d of hydrogen and a concentration [TR]d of total reducing components in exhaust gas in the exhaust gas passageway upstream of the NOx treating catalyst and downstream of the hydrogen enriching device.

    摘要： An exhaust gas purifying system for an internal combustion engine of an automotive vehicle. The exhaust gas purifying system comprises an exhaust gas composition regulating device for producing a low HC concentration reducing agent in a lean exhaust gas atmosphere where air-fuel ratio is leaner than a stoichiometric value. The exhaust gas composition regulating device is disposed in an exhaust gas passageway of the engine. The low HC concentration reducing agent is low in concentration of hydrocarbons to have an exhaust gas composition having a volume ratio of NOx/HC not less than 50 in the exhaust gas passageway immediately downstream of the exhaust gas composition regulating device. Additionally, a NOx treating catalyst is disposed in the exhaust gas passageway and located downstream of the exhaust gas composition regulating device. The NOx treating catalyst is arranged to reduce NOx in the presence of the low HC concentration reducing agent supplied from the exhaust gas composition regulating device. The exhaust gas composition of the low HC concentration reducing agent is obtained in the exhaust gas passageway immediately upstream of the NOx reducing catalyst.
