摘要:
An air-fuel ratio control apparatus estimates, on the basis of an exhaust air-fuel ratio of exhaust gas flowing into an exhaust purifying catalyst unit disposed in an exhaust passage of an engine, an emission of at least one specific component contained in exhaust gas flowing out of the exhaust purifying catalyst unit. The air-fuel ratio control apparatus performs the estimation by use of a model, and controls the air-fuel ratio in such a manner that the estimation value reaches a target state. The model is previously determined in consideration of the mass balance of the specific component.

A hydraulic drive control device which is capable of translating the effect of oil pressure loss reduction into the effect of fuel consumption reduction that is very real to the user. The hydraulic drive control device has (i) a driving hydraulic circuit for driving a hydraulic actuator by supplying pressure oil to or draining it from the hydraulic actuator through control valves, the pressure oil being discharged from a hydraulic pump driven by an engine and (ii) a quick return circuit for directly flowing part of hydraulic oil discharged from the hydraulic actuator back to a tank, while the hydraulic actuator being driven. The hydraulic drive control device also includes an engine controller for controlling the output of the engine such that the output of the engine is restricted when the quick return circuit is opened.

摘要:
In an exhaust gas purification device for an internal combustion engine, a NO.sub.X occluding and reducing catalyst is disposed in the exhaust gas passage of an engine. The NO.sub.X occluding and reducing catalyst absorbs NO.sub.X in the exhaust gas when the air-fuel ratio of the exhaust gas is at a lean air-fuel ratio and releases and reduces NO.sub.X when the air-fuel ratio of the exhaust gas is at a rich air-fuel ratio. The air-fuel ratio of the exhaust gas flowing out from the catalyst is detected by an air-fuel ratio sensor disposed in the exhaust gas passage downstream of the catalyst. When the air-fuel ratio of the exhaust gas flowing into the catalyst is changed from a rich air-fuel ratio to a lean air-fuel ratio, the air-fuel ratio of the exhaust gas flowing out from the catalyst stays at a stoichiometric air-fuel ratio before it changes to a lean air-fuel ratio. The length of the period in which the air-fuel ratio of the exhaust gas flowing out from the catalyst stays at a stoichiometric air-fuel ratio corresponds to the magnitude of the ability of the NO.sub.X occluding and reducing catalyst as a reducing catalyst. Thus, by measuring the length of the stoichiometric air-fuel ratio period of the exhaust gas flowing out from the NO.sub.X occluding and reducing catalyst, the ability of the NO.sub.X occluding and reducing catalyst as a reducing catalyst can be precisely evaluated.

A device for determining deterioration of a catalyst having an O.sub.2 storage capability and disposed in an exhaust passage of an engine comprises: upstream and downstream air-fuel ratio sensors disposed in the exhaust passage upstream and downstream of the catalyst respectively for detecting air-fuel ratios of exhaust gas upstream and downstream of the catalyst. The air-fuel ratio of the exhaust gas flowing into the catalyst is controlled on the basis of the output of the upstream air-fuel ratio sensor to make the air-fuel ratio flowing into the catalyst a target air-fuel ratio. A ratio of the length of the response curve of the output of the downstream air-fuel ratio sensor to the length of the response curve of the output of the upstream air-fuel ratio sensor is calculated. A ratio of the frequency of the output of the downstream air-fuel ratio sensor to the frequency of the output of the upstream air-fuel ratio sensor is calculated. It is determined that the catalyst has deteriorated when the length ratio is greater than a first predetermined ratio, or when the length ratio is greater than a second predetermined ratio which is smaller than the first predetermined ratio and the frequency ratio is greater than a third predetermined ratio.
