Abstract: A catalyst is warmed up by a rapid heating control that retards ignition timing and increases an intake air amount. Then the warm up is completed or a transmission is shifted to a drive range, the ignition timing is gradually advanced and the intake air amount is gradually decreased. Therefore, an engine speed is smoothly changed from the rapid heating control to the normal control without a torque shock. Additionally, a beginning of the advancing of the ignition timing is delayed by a predetermined delay time relative to a beginning of the decreasing of the intake air amount. The decreasing of the intake air amount prevents undesirable increase of the engine speed caused by the advancing of the ignition timing.

Abstract: An exhaust-gas cleaning system removes at least nitrogen oxides contained in exhaust-gas from a combustion source. An ammonia-generation catalytic converter generates ammonia using constituents of at least some of the exhaust gas emitted from the combustion source during ammonia-generation operating phases. Downstream a nitrogen oxide reduction catalytic converter reduces nitrogen oxides which are contained in the exhaust gas emitted from the combustion source using the ammonia generated as reducing agent. A nitrogen monoxide generation unit is situated outside the combustion source, for enriching the exhaust gas which is fed to the ammonia-generation catalytic converter with generated nitrogen monoxide during the ammonia-generation operating phases. The system is used for cleaning exhaust gases of motor vehicle internal-combustion engines which are operated predominantly in lean-burn mode, removing nitrogen oxides which are contained therein.

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.

A bypass flow path in an exhaust pipe is located upstream of a primary muffler. A diaphragm can be provided to manipulate a damper which acts to close the exhaust flow to the primary muffler and open the bypass to an exhaust pipe to effectively bypass the primary muffler.

Abstract: A variable delivery pump is provided for use in a work system. The variable delivery pump includes a variable delivery control arrangement that uses reduced pressure from the variable delivery pump to control the delivery of fluid from the pump. The reduced pressure is directed to a first port of the variable delivery control arrangement and acts to bias the flow changing mechanism to a maximum position when the work system does not require fluid flow. When the work system needs pressurized fluid, the reduced pressure that is also being directed across a flow restrictor is progressively blocked thus causing a variable valve arrangement to controllably direct reduced pressurized fluid to a second fluid port of the flow changing mechanism in opposition to the pressurized fluid at the first fluid port. In the subject arrangement, small orifices requiring large flows is eliminated. Consequently, the subject control arrangement is not adversely subject to high viscosity oils.
