A device for purification of exhaust gas including: an exhaust gas passageconnected to an internal combustion engine; a particulate matter trapping devicewhich is disposed in the exhaust gas passage, and which traps particulate matters in exhaust gas; ozone supply meanswhich is connected to the exhaust gas passageand on an upstream side of the particulate matter trapping device, and which can supply ozone to the particulate matter trapping device; and an NO oxidizing catalystwhich is disposed in the exhaust gas passageand on an upstream of the ozone supply means, and which oxidizes NO in the exhaust gas.

Device for purification of exhaust gas

The invention makes use of an exhaust gas catalyst, comprising an active component comprising at least one type of metal from noble metals and transition metals; NOx-absorbing material for absorbing and releasing nitrogen oxides according to the surrounding nitrogen oxide concentration; and compounds represented by AOSOand/or AOS (A is a rare earth element).

Exhaust gas cleaning catalyst, exhaust gas cleaning device, and system comprising internal combustion engine

The present invention provides an exhaust gas purifying device including an electrically insulated hollow cylindrical case, a cylindrical outer circumferential electrode arranged on an inner wall of the hollow cylindrical case, a bar-shaped center electrode held on a center axis of the outer circumferential electrode, and a metallic hollow cylindrical body arranged between the outer circumferential electrode and the center electrode, wherein the metallic hollow cylindrical body is electrically insulated and has a plurality of holes to permit particulate matter to pass therethrough without being accumulated.

Exhaust gas purifying device

A device for controlling an internal combustion engine comprises a device for trapping particulate matter (PM) in exhaust gas in an exhaust passage, means for supplying ozone to the particulate matter trapping device from the upstream thereof to oxidize and remove PM deposited in the device, and means for interrupting the fuel injection of the internal combustion engine upon the execution of ozone supply by the ozone supply means. It is possible to prevent components consuming ozone, such as NOx, from being contained in the exhaust gas of the internal combustion engine, whereby ozone is effectively usable.

Device and method for controlling internal combustion engine

There is provided an exhaust purifying system for an internal combustion engine which can achieve a function of a catalyst without deteriorating a function of ozone at the time of oxidizing and removing PM by using the ozone. The exhaust purifying system for the internal combustion engine comprises a wall-flow type particulate filter () for collecting particulate matter in an exhaust gas inside an exhaust passage, wherein the catalyst () is supported only in a part of a partition wall () of the particulate filter defining a passage () on the downstream side of the partition wall (). In consequence, when ozone is supplied, since the ozone is introduced on the upstream side of the partition wall () in which the PM is collected, the ozone does not contact the catalyst supported only in the part of the partition wall defining the passage () on the downstream side of the partition wall. Therefore, it is prevented that the ozone is decomposed, and a PM oxidation function is achieved.

Exhaust purifying system for internal combustion engine

An exhaust gas purification system provided with a trapping device () arranged on an engine exhaust passage and trapping particulate matter in the exhaust gas, an ozone generator () for generating ozone, and an ozone adsorbent () able to adsorb ozone, wherein at least part of the ozone generated by said ozone generator is adsorbed by said ozone adsorbent and, when particulate matter trapped on said trapping device should be removed, ozone adsorbed on the ozone adsorbent is desorbed from the ozone adsorbent and supplied to the trapping device. Due to this, it is possible to use an ozone generator with a relatively low ozone generating ability to burn off PM trapped on a filter etc. efficiently.
