ABSTRACT:
In an engine cooling structure, an engine cover defines together with a cylinder a space connected through a cooling air inlet to a cooling air supply device. An exhaust muffler has an exhaust gas discharge opening formed near a back end part of a side, which is opposite to a side facing the cylinder, of the exhaust muffler. The opening is positioned at a height included in a vertical dimension of the cylinder. A cooling air passage, through which a cooling air taken in the space defined by the engine cover and the cylinder through the cooling air inlet flows, is formed so as to cool the cylinder and the exhaust muffler. The cooling air passage includes a main cooling passage for guiding part of cooling air used for cooling the cylinder through a space around the exhaust muffler to a space around the opening, and a cooling air bypass passage for guiding part of cooling air used for cooling the cylinder directly to the space around the opening.
