センサ取付構造。In a multi-cylinder engine having a water jacket in the cylinder head, an air-fuel ratio sensor mounting part is formed between the exhaust ports of adjacent cylinders in the cylinder head to communicate between the two exhaust ports and to mount an air-twist ratio sensor. At the same time, a cover having a large number of small holes surrounding the outer periphery of the main body of the air-fuel ratio sensor is disposed on the mounting portion so as to suppress exhaust flow between the two exhaust ports by the air-fuel ratio sensor mounting portion. This is an air-fuel ratio sensor mounting structure for a multi-cylinder engine.
