摘要： An adsorbent state determining apparatus is provided for accurately determining the state of an adsorbent including a deterioration as well as for allowing for recovery of the adsorbent if its adsorbent performance can be restored. The adsorbent state determining apparatus determines the state of an adsorbent for adsorbing hydrocarbons contained in exhaust gases. An upstream and a downstream temperature sensor are provided at upstream and downstream locations of the adsorbent in an exhaust system for detecting temperatures of exhaust gases upstream and downstream of the adsorbent. An engine water temperature sensor detects an operating state of the engine. An ECU estimates the temperature of the exhaust gas which should be detected downstream of the adsorbent during adsorption of the adsorbent based on the upstream temperature detected by the upstream temperature sensor and an engine water temperature of the engine detected by the engine water temperature sensor. The ECU then compares the estimated downstream temperature with the detected downstream temperature detected by the downstream temperature sensor during adsorption of the adsorbent to determine the adsorption state of the adsorbent.

摘要： An emission control device and method are provided for treating exhaust to reduce pollutants contained therein. The device includes a first chamber through which the exhaust passes. First and second metal grids are disposed within the first chamber at a predetermined distance from each other. Voltage is supplied to the insulated first grid by an electrical induction coil at a predetermined frequency depending upon the application. Electrical charges are generated between the first and second grids which electrically ionizes the exhaust stream. The exhaust stream is then further treated at a second chamber having strata. The strata can further include or exclude noble metals for treatment of the exhaust.

摘要： Carbon-containing particulates like soot included in an exhaust gas of an internal combustion engine are collected by means of a heat-resistant filter medium. The filter medium dispersedly collects hydrocarbon compounds and the carbon-containing particulates included in the exhaust gas. Even when the exhaust gas has a lower temperature than the combustible temperature of the carbon-containing particulates, such dispersed collection ensures start of a preliminary oxidation reaction of the collected hydrocarbon compounds with oxygen included in the exhaust gas. The collected hydrocarbon compounds and the collected carbon-containing particulates are then subjected to combustion with the exhaust gas having a filter inflow temperature lower than the combustible temperature of the carbon-containing particulates by utilizing the reaction heat and active species produced by the reaction. This technique thus simply but securely regulates and reduces the carbon-containing particulates included in the exhaust gas.

摘要： An exhaust purifying apparatus for an internal combustion engine includes a catalyst that purifies exhaust gas from the engine, a first passage that allows exhaust gas to flow from the engine to the catalyst, and a second passage that allows exhaust gas to flow from the engine to the catalyst. The first passage includes an accelerated cooling portion whose cross section is designed so that a relatively large quantity of heat is released from the exhaust gas in the first passage, and the second passage has a cross section designed so that a relatively small quantity of heat is released from the exhaust gas in the second passage. The apparatus further includes a flow amount controller that controls amounts of exhaust gas flowing through the first and second passages, such that the amount of exhaust gas flow through the first passage is made larger than that through the second passage when the temperature of exhaust gas emitted from the engine is to be lowered by a relatively large degree before reaching the catalyst, and such that the amount of exhaust gas flow through the second passage is made larger than that through the first passage when the temperature of exhaust gas emitted from the engine is to be lowered by a relatively small degree before reaching the catalyst.
