摘要： An engine C/U 51 detects an abnormality which has occurred in an engine, and outputs a signal that indicates the occurrence of this abnormality to an SCR-C/U 61. The SCR-C/U 61 increases and decreases the urea water injection quantity corresponding to the abnormality which has occurred. On the other hand, the SCR-CU 61 detects an abnormality that has occurred in the SCR device, and outputs a signal that indicates the occurrence of this abnormality to an engine C/U 51. The engine C/U 51 controls an engine part such as an EGR valve, to reduce the NOx emission amount.

摘要： A concentration sensor for detecting a concentration of a liquid reducing agent through heat transfer characteristics between separate two points is provided in a storage tank for storing a liquid supplied to an NOx reduction catalyst. When the concentration read from the concentration sensor is 0% or less, the liquid is discriminated to be water, that is, it is utilized that when water is converted to the concentration of a liquid reducing agent, it is 0%, and it is also 0% even when the concentration is reduced by convection. When the concentration is greater than a predetermined value, it is discriminated that no liquid is present, since it is considered that the output of the sensor is abnormal because of the absence of a liquid in the tank. On the other hand, when the concentration is greater than 0% and less than a predetermined value, the liquid is discriminated to be the liquid reducing agent, provided that the concentration value may include an error.
摘要翻译：在用于储存供给到NOx还原催化剂的液体的储罐中设置有用于通过分离的两点之间的传热特性来检测液体还原剂的浓度的浓度传感器。当从浓度传感器读取的浓度为0％以下时，将液体判断为水，即利用当将水转化为液体还原剂的浓度时为0％，即使当通过对流降低浓度时也是0％。当浓度大于预定值时，鉴别出不存在液体，因为考虑到传感器的输出由于在罐中没有液体而异常。另一方面，当浓度大于0％且小于预定值时，只要浓度值可能包括误差，则液体被鉴别为液体还原剂。

摘要： A discriminating apparatus of liquid reducing agent is disclosed, in which, based on concentration of liquid reducing agent which is measured at each predetermined time after starting of engine, discrimination is processed whether the storage tank is filled with dissimilar aqueous solution, the storage tank is normally filled with the liquid reducing agent, or the storage tank is empty. When the empty discrimination or the dissimilar aqueous solution discrimination is performed, it is judged whether or not the discrimination is adequate according to the liquid condition in the storage tank. When the empty or the dissimilar aqueous solution discrimination is adequate, the empty discrimination frequency or the dissimilar aqueous solution discrimination frequency is counted up. When the empty discrimination frequency and the dissimilar aqueous solution discrimination frequency become equal to or larger than the first predetermined frequency, the discrimination is upheld.

摘要： Each of a first and a second number of times is counted, in which the first number of times indicates a condition where a concentration of a liquid reducing agent indirectly measured based on a characteristic of heat transmission between two separated points is successively determined to be equal to or higher than an upper limit threshold for no agent, and the second number of times indicates a condition the concentration is successively determined to be equal to or lower than a lower limit threshold for different agent. When the former becomes equal to or larger than the predetermined value, determination is made that no liquid reducing agent remains. When, the latter becomes equal to or larger than the predetermined value, determination is made that the liquid reducing agent is a solution of a different kind. When the former and the latter is less than the predetermined value, determination is made that correct liquid reducing agent remains.

摘要： A temperature-sensitive type urea sensor 74 is adopted for use in an engine exhaust gas purifying apparatus. The magnitude of convection of urea aqueous solution generated in a storage tank 41 is determined based on temperature information detected by the urea sensor 74. For detection of abnormality, a detected concentration Dn is adopted when the percentage GRDt of temperature change of urea aqueous solution is small, so that convection is small and it is determined not to affect accurate detection of an abnormality.
