Document Type and Number:
Japanese Patent JP2009133228
Kind Code:
A
Abstract:
To provide an exhaust gas aftertreatment device capable of improving flexibility in a case structure while inhibiting the device from getting larger, and capable of improving a NOx conversion rate by SCR catalyst by sufficiently diffusing a reducer.
An exhaust gas passage in an exhaust gas purification case 10 is constructed to make exhaust gas flow to an exhaust gas flow-out chamber 34 from an exhaust gas flow-in chamber 32, through a first pipe 18 having DPF 42 disposed therein, an another end turn chamber 32, a second pipe 20 in which urea water is added, a one-side turn chamber 28, and a third pipe 22 having a SCR catalyst 44 disposed therein.
