摘要： An IC engine has a single exhaust gas regulation (EGR) control valve (12,13) to feed back a variable proportion of the exhaust gases into the inlet manifold. The total gas flow in the engine is measured, as is the amount of fresh air intake. A processor calculates the difference between the two gas values to determine the amount of EGR.

摘要： A gas concentration detecting device for detecting the concentration of a component, such as an oxygen in an exhaust gas of an internal combustion engine. The device has a concentration detecting body 2 for detecting the oxygen and a cover 3 of a double wall structure which is for encircling the portion of the detecting body opened to the flow of the exhaust gas to be detected. The cover 3 has, at its axial tip end wall, a plurality of holes 33 and 34 arranged in such a manner that one of the holes functions as a gas inlet hole and the other hole functions as a gas outlet hole in order to cause the gas to be smoothly ventilated. The cover has, at its side, a wall of a closed structure with no hole for the passage of the gas, which is effective for preventing the cover 3 and the detecting body 2 from being cooled by the exhaust gas, thereby enhancing a heat retaining capacity, thereby preventing particulates from being deposited.

摘要： PROBLEM TO BE SOLVED: To provide an exhaust purification device that accelerates combustion of a combusting agent and reduces ejection of the combustion agent in an uncombusted state.SOLUTION: A valve control part 33 changes an opening degree of a flow rate control valve 16 and controls a flow rate of exhaust flowing through a bypass path 26. By changing the flow rate of the exhaust flowing through the bypass path 26 using the flow rate control valve 16, the flow rate of the exhaust is changed in an exhaust path 21 having exposed heat generating part 24, and a temperature in the heat generating part 24 is changed. An electric resistance R of the heat generating part 24 or a temperature T in the heat generating part 24 is controlled within a range of a predetermined setting temperature Ta by the change of the opening degree of the flow rate control valve 16. Combustion of combusting agent injected from a combustion agent injection valve 13 is accelerated by contact with a high-temperature heat generating part 24. Accordingly, the temperature of the exhaust and an oxidized catalyst 12 is increased.
