A catalytic converter of an internal combustion engine may include: at least one inlet channel having an end through which an exhaust gas is flowed into and the other end which is blocked; at least one outlet channel having an end which is blocked and the other end through which the exhaust gas is discharged; and a wall defining a boundary between neighboring inlet channel and outlet channel, and adapted to flow the exhaust gas from the inlet channel to the outlet channel, wherein the wall includes a single-layered portion formed at an end portion and having a three-way catalyst layer, and a multi-layered portion being the portion other than the single-layered portion and having a three-way catalyst layer, a hydrocarbon trap layer and an insulating layer. An apparatus of purifying an exhaust gas is also provided.

Catalytic converter of internal combustion engine and apparatus for purifying exhaust gas provided with the same

A system for regenerating a particulate filter mounted on an exhaust pipe of a gasoline engine including a plurality of cylinders and an ignition device for igniting fuel and air in the cylinder, a three-way catalyst device mounted on the exhaust pipe connected to the gasoline engine, and to oxidize or reduce exhaust gas, the particulate filter mounted on the exhaust pipe downstream of the three-way catalyst device to trap particulate matter and regenerate the particulate matter using heat of the exhaust gas, a differential pressure sensor mounted upstream and downstream of the particulate filter and to measure a pressure difference of the particulate filter, and a control portion to receive the measured pressure difference and control parameters to determine an amount of non-ignited fuel which is not ignited and flows to the three-way catalyst device among the fuel flowing into the plurality of cylinders.

System and method for regenerating gasoline particulate filter

An exhaust gas purification device may deactivate at least one of cylinders to supply a gasoline particulate filter with sufficient air according to a driving condition of a gasoline engine, and a control method thereof and a control method thereof may include comparing a pressure difference of the gasoline particulate filter with a predetermined value, determining a cylinder that may be to be deactivated when the pressure difference may be larger than the predetermined value, regenerating the gasoline particulate filter by supplying it with air through the deactivated cylinder, determining whether the engine may be in an over-run condition during the regeneration process, and returning to a general driving condition in a case that the engine may be in the over-run condition.

System for purifying exhaust gas and method for controlling the same

An aging device of a catalytic converter of a vehicle simulates wear-and-tear of a catalytic converter under conditions that simulate to those of a real vehicle by injecting an oil additive or an engine oil mixture containing phosphor (P), zinc (Zn), and etc., into an engine.
