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： The engine performance of an engine unit including a dedicated reed valve (84) and a dedicated secondary air supply passage member (87) downstream of a dedicated reed valve and the purification performance of purifying exhaust gas are both achieved. An engine unit (11) of a straddled vehicle (1) includes an upstream secondary air supply passage member (88a), a secondary air supply valve (83), a downstream secondary air supply passage member (88b), a dedicated reed valve (84), a dedicated secondary air supply passage member (87) downstream of the dedicated reed valve, a dedicated exhaust passage member (66), and a gas state detection device 70 which is not for the dedicated secondary air supply passage member, which is configured to detect an index indicating the state of gas in a passage member other than the dedicated secondary air supply passage member (87) downstream of the dedicated reed valve. A secondary air supply control unit (91) is configured to control the secondary air supply valve (83) to be in an open state when the engine main body (20) is driven under a cold state. In this case, a detection unit (96) is able to detect clogging of the dedicated secondary air supply passage member (87) downstream of the dedicated reed valve based on a signal of the gas state detection device (70) which is not for the dedicated secondary air supply passage member.

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).
