ABSTRACT:
A two-cylinder engine comprises a first cylinder and a second cylinder adapted to perform explosions at such timing that an interval from explosion in the first cylinder to explosion in the second cylinder becomes shorter than an interval from the explosion in the second cylinder to the explosion in the first cylinder, a single carburetor, and an intake manifold having an intake passage communicating with the carburetor and first and second branch passages branched from the intake passage and communicating with the respective cylinders. The intake passage and the branch passages are arranged such that an angle formed between an axis of the intake passage and an axis of the first branch passage becomes smaller than an angle formed between the axis of the intake passage and an axis of the second branch passage.
