A multi-cylinder engine comprising: at least three or more of plural cylinders that are arranged in an array; plural intake ports (17A to 18D) that respectively communicate with the plural cylinders ; and an air intake passage that is connected to each of the plural intake ports (17A to 18D), characterized in that for each of the plural cylinders , the plural intake ports (17A to 18D) include an SCV port that is configured to reduce a flow rate of flowing gas via a swirl control valve , the air intake passage has: plural independent passages that are respectively connected to the plural intake ports (17A to 18D); a surge tank , to which upstream end portions of the plural independent passages are connected so as to be arranged in line according to an alignment order of the corresponding cylinders ; and plural upstream passages , a downstream end portion of each of which is connected to the surge tank , and each of which introduces the gas into said surge tank , and the plural upstream passages are arranged with a space being interposed therebetween in a cylinder array direction, and, when the surge tank is seen in a cylinder axis direction, the plural upstream passages are connected to the surge tank on extension lines (L1, L2; L1', L2'), each of which extends from the upstream end portion of the independent passage connected to the SCV port to an opposite side to the plural cylinders . at least three or more of plural cylinders that are arranged in an array; plural intake ports (17A to 18D) that respectively communicate with the plural cylinders ; and an air intake passage that is connected to each of the plural intake ports (17A to 18D), characterized in that for each of the plural cylinders , the plural intake ports (17A to 18D) include an SCV port that is configured to reduce a flow rate of flowing gas via a swirl control valve , the air intake passage has: plural independent passages that are respectively connected to the plural intake ports (17A to 18D); a surge tank , to which upstream end portions of the plural independent passages are connected so as to be arranged in line according to an alignment order of the corresponding cylinders ; and plural upstream passages , a downstream end portion of each of which is connected to the surge tank , and each of which introduces the gas into said surge tank , and plural independent passages that are respectively connected to the plural intake ports (17A to 18D); a surge tank , to which upstream end portions of the plural independent passages are connected so as to be arranged in line according to an alignment order of the corresponding cylinders ; and plural upstream passages , a downstream end portion of each of which is connected to the surge tank , and each of which introduces the gas into said surge tank , and the plural upstream passages are arranged with a space being interposed therebetween in a cylinder array direction, and, when the surge tank is seen in a cylinder axis direction, the plural upstream passages are connected to the surge tank on extension lines (L1, L2; L1', L2'), each of which extends from the upstream end portion of the independent passage connected to the SCV port to an opposite side to the plural cylinders . <EOS>
