Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a catalytic reaction system capable of maintaining homogenization of a reducing agent in a catalyst inlet.

SOLUTION: A catalytic reaction system 10 includes: a catalyst 11 provided in an exhaust passage 91 of an engine 90; a mixer 12 provided upstream of the catalyst 11; an injection device 13 injecting a spray of a liquid reducing agent toward the mixer 12; and a spray control section 24 controlling injection particle size and injection speed of the injection device 13 in accordance with the state of exhaust gas in the exhaust passage 91 serving as a catalyst installation passage section, in order to promote atomization or vaporization of the spray downstream of the mixer 12.
