摘要： A compact Selective Catalytic Reduction (SCR) system comprising a system inlet, a gas flow system and a plurality of catalyst clusters is described. The system inlet is configured to utilize heat of the cleaned exhaust to vaporize a solution of a reductant, or a precursor of a reductant, and to mix the vaporized reductant with exhaust gas to form a mixed gas. The gas flow system is configured to provide the mixed gas from the system inlet to a plurality of catalyst clusters and to provide heat from the exhaust gas to assist in vaporization of the reductant/precursor and to assist in the conversion of the precursor to the reductant. The plurality of catalyst clusters comprise SCR and ASC catalysts but can also include filter functionality.

摘要： An exhaust system for a motorcycle includes an exhaust muffler (35F) with inclined side walls (47a, 47b) and is formed in an inverted trapezoid shape in a rear view. An exhaust gas conduit (51) passes through a front wall (47e) of the exhaust muffler (35F) and has a bent section (51 a) within the exhaust muffler (35F), which changes the flow direction of exhaust gas from longitudinal to lateral. A catalyst casing (50) which has one end connected to the exhaust gas conduit (51) is arranged to be inclined downwardly to one side. The catalyst casing can thus be accommodated in the exhaust muffler arranged behind and beneath an engine main body, which makes it easy to ensure a bank angle and to ensure catalyst capacity and the flow length of exhaust gas to thereby improve a purification performance.

摘要： An exhaust device 40 includes: left and right exhaust pipes 41 L, 41 R; and mufflers 44L, 44R connected to downstream ends of the exhaust pipes 41 L, 41 R. The pair of left and right exhaust pipes 41 L, 41 R respectively includes a merging portion 43L, 43R with a catalyst 48L, 48R provided therein. The pair of left and right exhaust pipes 41 L, 41 R respectively includes, downstream of the catalyst 48L, 48R, a branching portion 55L, 55R which has one side thereof extending to the muffler 44L, 44R, and the other side thereof extending to a connecting pipe 54. An oxygen sensor 52 is provided on a downstream side of one of the pair of left and right branching portions 55L, 55R.
The oxygen sensor 52 can detect oxygen in the exhaust gas in a state where the exhaust gas is sufficiently stirred, and this can lead to a reduction in the size of the catalyst.
