Internal combustion engine, vehicle, marine vessel, and exhausting method for internal combustion engine
(57)    Abstract

A novel internal combustion engine is provided by applying means for increasing the velocity of exhaust gas. An internal combustion engine 1 includes a branch section 21 for branching a shock wave 35 propagating at a higher velocity than exhaust gas 36 and for guiding the branched shock wave,

and a reflecting section 21b provided in the branch section 21. The reflecting section 21b reflects and returns the shock wave 35 back to an exhaust path 16 and causes the shock wave 35 to collide against the exhaust gas 36, thereby increasing the pressure of the exhaust gas 36. In accompaniment with the exhaust gas 36 passing a divergent section 33 of a

convergent-divergent nozzle 31, a new shock

wave propagating in a downstream direction in the exhaust path 16 is generated, and the temperature and pressure of the exhaust gas 36 are
