IPC: F01N3/20
Filed: 2019-08-28
Abstract: An exhaust flow path (42) of an internal engine (1) allows an exhaust gas discharged from a combustion chamber (20) to flow. A reducing agent supply unit supplies a reducing agent to the exhaust flow path (42) through a nozzle (61) attached in the exhaust flow path (42) such that the reducing agent is mixed with the exhaust gas. A reactor (66) makes the exhaust gas, induced from the exhaust flow path (42), come in contact with a catalyst to perform a denitrification process. A flue (81) guides the exhaust gas having passed through the reactor (66). A bypass flow path (681) connects the exhaust flow path (42) to the flue (81) while bypassing the reactor (66). A bypass valve (682) opens and closes the bypass flow path (681). A supply control unit, if sensing a valve opening process of the bypass valve (682), controls the reducing agent supply unit to stop supplying the reducing agent to the exhaust flow path (42). Therefore, the present invention can inhibit the inflow of a reducing agent into a more downstream side than the reactor (66).
