It is assumed that the straddled vehicle 1 is viewed in an up-down direction. The upstream end 35a of a silencer 35 is provided one of leftward and rightward of the downstream end 31 b of a cylinder exhaust passage member 31. A main catalyst 39 is arranged so that the center of the downstream end is on the one of the leftward and rightward of the center of the upstream end. The main catalyst 39 is provided to at least partially overlap a quadrangle S10 which is formed of a side S11 which passes the downstream end 31 b of the cylinder exhaust passage member 31 and is parallel to a cylinder axis Cy1, a side S12 which passes the downstream end 31b of the cylinder exhaust passage member 31 is parallel to a crankshaft axis Cr1, a side S13 which passes the upstream end 35a of the silencer 35 and is parallel to the cylinder axis Cy1, and a side S14 which passes the upstream end 35a of the silencer 35 is parallel to the central axis of the crankshaft axis Cr1.

摘要： A straddled vehicle in which variation in purification performance of purifying exhaust gas can be restrained is provided.
An engine unit 11 mounted on a straddled vehicle 1 includes: an engine main body 20 including a combustion chamber 36; an exhaust passage member 43 allowing exhaust gas to flow from the combustion chamber 36 to a discharge port 42e; and an upstream catalyst 46 which is the most upstream catalyst in the exhaust passage member 43 in the flow direction of the exhaust gas. A catalyst layer 49 of the upstream catalyst 46 includes a noble metal and has a function of purifying the exhaust gas which is higher than a function of chemical reaction with phosphorus in the exhaust gas. The upstream catalyst 46 includes a phosphorus adhesion reduction portion 44 which restrains adhesion of phosphorus to the catalyst layer 49. The phosphorus adhesion reduction portion 44 includes either a phosphorus chemical reaction portion or a phosphorus barrier layer. The phosphorus chemical reaction portion is provided at least at a part from the upstream end to the center of the catalyst layer 49 in which the length L is arranged to be longer than the length D, and in the phosphorus chemical reaction portion, a function of chemical reaction with phosphorus in the exhaust gas is higher than a function of purifying the exhaust gas. The phosphorus barrier layer occupies at least a half of the entire surface of the catalyst layer 49 stacked on a base 48 made of metal, and has a function of being less likely to react with phosphorus.

摘要： An object is to restrain the influence of heat from a catalyst to vehicle components while improving the purification performance of purifying exhaust gas by the catalyst in a unit-swing-type single-cylinder four-stroke engine unit. An engine main body (94) is swingably supported by a vehicle body frame (81) by a swing supporter (120), and is provided below at least one vehicle component. A main catalyst (116) is provided in an exhaust pipe (111) and purifies exhaust gas exhausted from one combustion chamber (106) most in an exhaust path from the one combustion chamber (106) to a discharge port (112e). In the left-right direction, the main catalyst (116) is provided at least partially to the right of the right end of the swing supporter (120) (or to the left of the left end of the swing supporter (120)). When the straddled vehicle is viewed in the up-down direction, the main catalyst (116) is provided at least partially outside an engine main body (94).

摘要： A vehicle on which a single-cylinder four-stroke engine unit which is able to stably detect the oxygen density in exhaust gas is mounted is provided.
A single-combustion-chamber main catalyst 39 is at least partially positioned frontward of a crankshaft axis Cr1, and purifies the exhaust gas exhausted from one combustion chamber 29 most in an exhaust path extending from the one combustion chamber 29 to a discharge port 35e. A single-combustion-chamber upstream oxygen detector 37 is provided upstream of the single-combustion-chamber main catalyst 39 in the flow direction of the exhaust gas. The path length from the one combustion chamber 29 to the single-combustion-chamber upstream oxygen detector 37 is longer than the path length from the single-combustion-chamber upstream oxygen detector 37 to the upstream end of the single-combustion-chamber main catalyst 39.
