A multi-cylinder engine comprising: at least three or more of plural cylinders (11A, 11B, 11C, 11D) that are arranged in an array; plural intake ports (17A to 18D) that respectively communicate with the plural cylinders (11A, 11B, 11C, 11D); 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 (11A, 11B, 11C, 11D), 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 (39, 391, 392) 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 (39, 391, 392) are connected so as to be arranged in line according to an alignment order of the corresponding cylinders (11A, 11B, 11C, 11D); and plural upstream passages (44b, 44c), 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 (44b, 44c) 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 (44b, 44c) 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 (391, 392) connected to the SCV port (17A, 18B, 18D) to an opposite side to the plural cylinders (11A, 11B, 11C, 11D). at least three or more of plural cylinders (11A, 11B, 11C, 11D) that are arranged in an array; plural intake ports (17A to 18D) that respectively communicate with the plural cylinders (11A, 11B, 11C, 11D); 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 (11A, 11B, 11C, 11D), 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 (39, 391, 392) 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 (39, 391, 392) are connected so as to be arranged in line according to an alignment order of the corresponding cylinders (11A, 11B, 11C, 11D); and plural upstream passages (44b, 44c), 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 (39, 391, 392) 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 (39, 391, 392) are connected so as to be arranged in line according to an alignment order of the corresponding cylinders (11A, 11B, 11C, 11D); and plural upstream passages (44b, 44c), 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 (44b, 44c) 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 (44b, 44c) 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 (391, 392) connected to the SCV port (17A, 18B, 18D) to an opposite side to the plural cylinders (11A, 11B, 11C, 11D).
