INTERNAL COMBUSTION ENGINE, EXHAUST GAS RECIRCULATION DEVICE, AND METHOD OF RECIRCULATING EXHAUST GAS

Japanese Patent JP2014163385

A

PROBLEM TO BE SOLVED: To utilize recirculation of an exhaust gas without increasing a risk of corrosion to a component unit of an internal combustion engine, with respect to the internal combustion engine operated with heavy fuel oil.SOLUTION: An exhaust gas (14) coming out from a cylinder (12) and capable of being supplied to a supercharger (15), can be branched at an upstream side of the supercharger (15) by using an exhaust gas recirculation device (23) including at least one exhaust gas recirculation cooler (25, 26), and can be mixed with a supply air (13) compressed after cooling. At least one additive agent (27, 34) can be introduced to the exhaust gas guided through the exhaust gas recirculation device (23) at an upstream side of an exhaust gas recirculation cooler (26) for cooling the exhaust gas guided through the exhaust gas recirculation device (23) to be lower than a dew point temperature of acid including sulfur, and at least one additive agent binds sulfur oxide of the exhaust gas, and/or neutralizes the acid including sulfur, generated in cooling the exhaust gas.
