In a combustion engine where an exhaust valve housing 11 is formed separate from a cylinder cover 16 and has an exhaust passage 11a, forced cooling of a peripheral wall 11f around the exhaust passage, as in a known construction of the exhaust valve housing, is omitted, and cooling chambers 11c, 12b for passage of a cooling agent are only provided at two places, that is, in a peripheral wall forming a sliding part for an exhaust valve 13 and in a peripheral wall forming a part of a valve seating 12. Hereby, the unwanted heat losses of the exhaust gas are reduced and at the same time, a sufficient cooling of the valve housing and the sliding part is obtained despite an elevated temperature of the valve housing, such that the lubrication ability of said sliding part is sustained. <IMAGE>
