摘要： The present disclosure relates to internal combustion engines. The teachings thereof may include monitoring a secondary air system with which secondary air is introduced into exhaust of the internal combustion engine wherein individual cylinders of the internal combustion engine are associated with one of at least two cylinder banks and a separate exhaust duct is associated with each cylinder bank. The methods may include delivering secondary air with a compression arrangement via a common secondary air line divided into a number of individual secondary air sublines corresponding to the number of exhaust ducts at a branching point downstream of the compression arrangement; controlling the secondary air to simultaneously enable or inhibit the flow to the individual secondary air sublines; detecting values for the pressure downstream of the compression arrangement and upstream of the branching point; detecting pulsations of a pressure in each cylinder bank when the compression arrangement is activated and the throughflow control arrangement set into the open state; summing the pulsations; comparing each of summed-up values with threshold values; and if the respective threshold value is exceeded, identifying a fault in the throughflow control arrangement.

摘要： Methods and systems are provided for regenerating a particulate filter in an engine exhaust, where burning of soot is initiated by introducing additional oxygen into the exhaust gas upstream of the particulate filter where an exhaust temperature exceeds a threshold, a soot burn rate controlled by adjusting pulsing of the additional oxygen. Further, the pulsing of the additional oxygen is introduced via a high-pressure EGR passage during boosted engine conditions.

摘要： To overcome problems concerning the sticking of the check plate in a combined check and control valve, a stop is provided on the valve rod or a guide element in the vicinity of the valve rod, whose distance to the limiting element is smaller than the maximum stroke and larger than the nominal stroke of the limiting element. Thus, it is achieved that the check plate is released from the valve seat by means of the stop, when the valve rod is displaced to the maximum.

Each flow path is provided with a particle filter for the removal of particulate matter from the exhaust gas, an NOx trap for the removal of NOx from the exhaust gas.

Thereby, both the particle filter and the NOx trap in at least one of the flow paths can be regenerated in a single operation. There is also provided a method for regenerating cleaning means for exhaust gas where the cleaning means comprises an NOx trap and possibly a particle filter.

摘要： A reactor that can be attached to the exhaust manifold of a diesel or gasoline engine, or other internal combustion engines such as a jet engine or a gas turbine to oxidize and burn carbon soot particles, carbon monoxide, and unburned hydrocarbons, and to dissociate nitrogen and sulfur oxides. The reactor has a reaction zone that contains porous heat-retaining foam cells and that is bounded by a porous heat-retaining zone, which in turn is surrounded by ceramic insulation materials to minimize energy losses. Engine exhaust at elevated temperatures and containing some oxygen (air) enters the reaction chamber. By means of impinging heat transfer, thermal radiation enhancement, energy trapping and combustion of engine emissions, temperatures sufficient to oxidize carbon soot particles, carbon monoxide, and unburned hydrocarbons are attained. Harmless product of the oxidation reactions, H.sub.2 O and CO.sub.2 are released from the reactor.

摘要： A combination muffler and catalytic converter for an exhaust system. The unit comprises an outer housing having an inlet to receive exhaust gases, and a venturi is located within the housing and provides an aspirating effect to draw air into the housing from the atmosphere for the catalytic conversion. The venturi includes a diverging conical outlet section, and the gases are discharged from the outlet section through a plurality of perforations which aids in obtaining a uniform distribution of the gases to the catalytic unit that is located centrally of the housing. After passing through the catalytic unit, the gases are discharged from the housing through a discharge pipe having a closed inner end and perforations in its wall through which the gases flow. The perforated discharge pipe provides a self-controlling system which prevents overheating of the catalyst.
