INTERNAL COMBUSTION ENGINE FOR SHIP

摘要

Provided are a cylinder section (2) that is supplied with air and fuel so as to generate rotational driving force and that discharges exhaust gas; an exhaust receiver (3) that receives the exhaust gas discharged from the cylinder section (2); an outer combustion tube (9) that receives the exhaust gas discharged from the exhaust receiver (3); an inner combustion tube (8) that is disposed inside the outer combustion tube (9) and ejects fuel and combustion air into the outer combustion tube (9) so as to combust the exhaust gas therein; a turbocharger (5) that is driven by the exhaust gas heated within the outer combustion tube (9) and discharged from the outer combustion tube (9) and that turbocharges the air to be supplied to the cylinder section (2); and a denitrator having a catalyst that reduces nitrogen oxide contained in the exhaust gas discharged from the turbocharger (5).
