Abstract
A catalytic converter for a vehicle includes an LNT converter into one side of which exhaust gas discharged from an engine flows and from the opposite side of which the exhaust gas. The LNT converter traps nitrogen oxide contained in the exhaust gas under a lean environment, desorbs the trapped nitrogen oxide under a rich environment, and reduces the nitrogen oxide contained in the exhaust gas or the desorbed nitrogen oxide. A connecting housing changes a direction of a path of the exhaust gas to a vertical direction, and allows a reducing agent to be injected to the exhaust gas. An SDPF converter changes a direction of a path of the exhaust gas to a direction opposite to a direction, captures particulate matters contained in the exhaust gas, and reduces nitrogen oxide contained in the exhaust gas using the injected reducing agent.
