Abstract: A diesel powered vehicle is provided with an SCR system which uses an external reducing reagent to convert NOx emissions in a manner which accounts for the effects of NOx transient emissions on the reducing catalyst. Actual NOx emissions produced by the engine are filtered using a variable NOx time constant in turn correlated to the reductant/NOx storage capacity of the reducing catalyst at its current temperature to account for changes in the SCR system attributed to NOx transient emissions. Catalyst temperature is filtered using a variable catalyst time constant corresponding to current space velocity of the exhaust gas to account for changes in the catalyst temperature attributed to NOx transient emissions. The reductant is metered on the basis of the filtered, corrected NOx concentration applied at a NSR ratio based, in turn, on the filtered, corrected reducing catalyst temperature.

Abstract: A connection of the exhaust emission control device, to which a collecting portion of an exhaust manifold extending rearwards and downwards from a rear face of a cylinder block is connected, is eccentric toward an engine block by a distance with respect to an axis of a cylindrical main casing. Therefore, the exhaust manifold can be located as close as possible to a rear face of the engine block to ensure that travel wind is difficult to collide with the exhaust manifold, thereby preventing a drop in temperature of an exhaust gas to early raise the temperature of the exhaust emission control device. Moreover, since the exhaust manifold is disposed closer to the rear face of the engine block, a collision stroke permitting the retraction of the engine upon frontal collision can be expanded.

Typically, a first electrode and a second electrode define an interelectrode space containing a stack of freezer packages.

The AC voltage generates conductivity AC in the inner conductive layers. An alternating electric field between adjacent conductive layers generates conductivity current in the ice, resulting in Joule heat, which melts the ice.

Abstract: An apparatus controls a variable displacement compressor used in a refrigerant circuit. The compressor includes a drive shaft, which is rotated by an engine. When the drive shaft rotates, the compressor compresses refrigerant sent from the external refrigerant circuit and discharges the compressed refrigerant to an external refrigerant circuit. When the displacement of the compressor is minimized, the circulation of refrigerant in the refrigerant circuit is stopped. The apparatus has a control mechanism for varying the pressure in the crank chamber. A detector detects a physical quantity that reflects the heating status of the compressor. When the compressor displacement is minimized and the quantity detected by the detector indicates that the heating status of the compressor is deteriorating, a controller commands the control mechanism such that the displacement of the compressor is greater than the minimum displacement.
