  "textContent": "A diesel engine reduces CO2 emission by increasing the combustion rate of ammonia while reducing unburned ammonia. The diesel engine includes : a combustion chamber; and a fuel charging unit that charges a fuel oil, used as an ignition source, and gaseous ammonia into the combustion chamber, in which an ammonia premixed gas is formed in the combustion chamber by the fuel charging unit, and where the ammonia premixed gas is subjected to mixed combustion. The diesel engine includes a control unit configured to control the formation of the ammonia premixed gas so that a concentration of ammonia in the combustion chamber becomes higher in an area closer to an inner side wall surface of the combustion chamber, rather than in a central portion of the combustion chamber. the control unit adjusts an air excess ratio to be lower than an air excess ratio at the time of operation only with a fuel oil.",
