摘要： A process and an apparatus for treating exhaust gas from an internal combustion engine include at least two exhaust-gas treatment modules. An exhaust gas stream can be at least partly deflected depending on a load state of the internal combustion engine in such a way that at least parts of the exhaust gas flow through one or more modules. This makes it possible to advantageously construct and operate even an exhaust gas system of large-volume internal combustion engines, in which conversion and treatment of the exhaust gas is carried out in individual modules, even in no-load operation, basically at very low exhaust gas mass flow rates. The individual modules can be adapted to various load levels of the internal combustion engine. A rail-borne vehicle and a water-borne vehicle having the apparatus are also provided.

摘要： An exhaust gas throttle valve disposed in the exhaust system of an engine, wherein the center axis of rotation of a valve shaft 5 is set at a position deviated from the center axis of the exhaust gas passage, and two recessed portions 11 are symmetrically formed in the circumferential portion of a valve body 4 by cutting the surface thereof. The positions where the recessed portions 11 are formed are on the side of the center axis of the exhaust gas passage beyond the center axis 12 of rotation, and at where the peripheral portion of the valve body 4 faces the edge portions 9 where insertion holes 8 for the valve shaft 5 are opened in the exhaust gas passage. At these positions, the distance is a minimum between the peripheral portion of the valve body 4 and the edge portions 9. The recessed portions 11 work to increase the gap relative to the edge portions 9 at that positions. It is therefore made possible to approximate the peripheral portion of the valve body 4 to the tubular wall of the exhaust gas passage 2 when the exhaust gas throttle valve is closed preventing the valve body 4 and the edge portions 9 from coming in contact together despite of the thermal expansion.

摘要： A system and method are provided for controlling regeneration of exhaust gas aftertreatment components coupled to an internal combustion engine. For example, the particulate load of a particulate filter is monitored and a road speed of the vehicle is determined. If the particulate load is greater than a particulate load threshold and the road speed is greater than a road speed threshold, regeneration of the particulate filter is initiated. As another example, the sulfur oxide load (SOx) of a NOx catalyst is also monitored, and if the SOx load is greater than a SOx threshold while the particulate filter is being regenerated, regeneration of the particulate filter is terminated and SOx regeneration of the NOx catalyst is initiated.

摘要： An exhaust emission control system [1] comprising a continuous regenerating DPF [13] and a DPF controlling means [30C], wherein control is so performed as to accept the operation of a forced regenerating means [34C] at an operation request by a driver when it is judged a traveling distance [ΔMc] after starting collection detected by a traveling distance detecting means [33C] has reached a specified judging traveling distance [ΔM1] even when the DPF controlling means [30C] detects a collection amount [ΔPm] detected by a collection amount detecting means [32C] is smaller than a specified judging collection amount [ΔP1]. Accordingly, in a continuous regenerating DPF [13] capable of manual regenerating, the number of warning such as a blinking regeneration button prompting a manual regeneration is reduced to relieve a driver of trouble.

摘要： An exhaust emission purifying apparatus of the present invention has a casing that includes therein a plurality of layered passages which is formed by partitioning an inside of the casing to thereby allow an exhaust passage from an exhaust emission inlet to an exhaust emission outlet to be folded in its direction once or more, a reduction catalyst that reductively purifies NOx by using a reducing agent, a nozzle that injects the reducing agent or a precursor thereof to an exhaust upstream side of the reduction catalyst, and a filter (DPF) that collects PM suspended in an exhaust emission. The reduction catalyst and the filter are disposed in the different layered passages. Consequently, a more compact exhaust emission purifying apparatus having both NOx removal function and PM collection function can be provided.

摘要： A temperature of a catalyst disposed in an exhaust system is raised to a target bed temperature by supplying an unburned fuel component to the catalyst. A learned value is updated based upon a catalyst bed temperature under a temperature increase control and the target bed temperature so that the learned value corresponds to a difference between the respective temperatures. Whether the learned value is out of a proper range or not is determined whenever the learned value is updated. Abnormality is determined when determination that the learned value is out of the proper range is made over several successive updates of the learned value.
