The present invention relates to a clean engine with an easily detachable exhaust pipe connection structure, which can improve assembly and maintenance by conveniently detaching an exhaust pipe from an exhaust port of a cylinder head. According to the clean engine of the present invention, an exhaust extended body is extended to protrude further upward than an intake port of a cylinder head and has an exhaust port formed therein, wherein an outlet of the exhaust port faces a side direction in a position higher than that of the intake port, a side flange is formed on the side front end of the exhaust extended body which forms the outlet of the exhaust port, an end flange of an exhaust connection pipe is in contact with the side flange of the exhaust extended body, and a bolt is inserted in a direction from the cylinder head to the exhaust connection pipe to couple the side flange of the exhaust extended body and the end flange of the exhaust connection pipe. The clean engine of the present invention can easily perform attachment and detachment of the exhaust connection pipe without interference with complex adjacent structures such as the exhaust connection pipe, an exhaust gas receiver, an insulation cover, and a water jacket by extending the exhaust extended body to protrude from the top of the cylinder head, forming the exhaust port in the upwardly protruding exhaust extended body while arranging the outlet of the exhaust port to face the side, and inserting the bolt in the direction from the cylinder head to the exhaust connection pipe to couple the side flange of the exhaust extended body and the end flange of the exhaust connection pipe. |
