摘要： An insulation structure of catalytic converter of vehicle according to an exemplary embodiment of the present invention includes an LNT converter. A connecting housing is provided such that a urea reducing agent is injected to the exhaust gas when it is needed. An SDPF converter reduces nitrogen oxide contained in the exhaust gas using the injected reducing agent, and SCR catalyst is coated on a filter. An insulation cover including inner surface contacts the LNT converter, the connecting housing and the SDPF converter and also includes an outer surface which is opposing surface to the inner surface and surrounds the LNT converter, the connecting housing and the SDPF converter. The insulation cover insulates heat generated from the LNT converter, the connecting housing and the SDPF converter. An insulation material is inserted and attached between the outer surface and the inner surface of the insulation cover.

摘要： Disclosed are a method of correcting a control logic of a selective catalytic reduction (SCR) catalyst and an exhaust system. The control logic may be adapted to calculate an injection amount of a reducing agent for the SCR catalyst at the least. The method may include detecting input variables including temperature of the SCR catalyst and exhaust flow rate, discretizing the input variables, standardizing the discretized input variables, determining whether the discretized input variables are within a correction range, and correcting the control logic of the SCR catalyst if the discretized input variables are within the correction range.

摘要： A method of regenerating a lean NOx trap (LNT) of an exhaust purification system provided with the LNT and a selective catalytic reduction (SCR) catalyst may include: determining whether a regeneration release condition of the LNT is satisfied; determining whether a regeneration demand condition of the LNT is satisfied; and performing regeneration of the LNT if the regeneration release condition of the LNT and the regeneration demand condition of the LNT are satisfied. In particular, the regeneration release condition of the LNT is satisfied if all of an engine operating condition, an LNT state condition, and a lambda sensor synchronization condition are satisfied.
