ABSTRACT:
A disclosed engine assembly comprises an engine; a crank shaft having an end extending outward from inside the engine; a rotating body mounted at the end of the crank shaft; a cover body mounted on the engine so as to cover the rotating body; the cover body comprising a lower cover that covers at least lower part of the rotating body and an upper cover connected to the lower cover so as to cover at least upper part of the rotating body; the lower cover having at least one ventilating intake port for sucking hot air located around the engine under the intake port; the upper cover having a ventilating exhaust duct for discharging the sucked hot air; the rotating body including a timing belt located near one side of the engine, a tensioner located near one side of the engine and having a mounting position adjustment bolt for adjusting a tension on the timing belt, and a manually starting pulley located on one side of the engine outside the timing belt; and the starting pulley having at least one opening located so as to engage with the amounting position adjustment bolt of the tensioner. This constitution enables hot air existing around the engine under the lower cover to be discharged smoothly to the outside of the engine cover via the cover body, thereby preventing hot air from being stranded under the lower cover. In addition, the position of the mounting position adjustment bolt can be perceived easily by simply aligning the opening with the bolt.
