摘要： An internal combustion engine is provided in which an intake valve (9), which opens and closes an intake valve hole (7) formed in a cylinder head (3) so as to face a combustion chamber (5), has a hollow structure, and an exhaust valve hole (22) formed in the intake valve (9) is made to open and close by an exhaust valve (18) coaxially housed within the intake valve (9). The intake valve hole (7), which faces the combustion chamber (5), communicates directly with an intake port (8), and the exhaust valve hole (22), which faces the combustion chamber (5), communicates with an exhaust port (14) via an exhaust passage (21) formed within the hollow intake valve (9). It is thereby possible to ensure that the intake valve (9) has a large opening area, thus increasing the intake charging efficiency and, furthermore, since exhaust gas that has just come out of the combustion chamber (5) does not make direct contact with the cylinder head (3), which has a large heat capacity, any decrease in temperature of the exhaust gas can be minimized, thereby utilizing waste heat effectively.
