摘要： In an SCR apparatus mounted on a vehicle, the concentration of a reducing agent or a precursor thereof contained in an aqueous solution of the reducing agent or the precursor is accurately detected. In sensing the concentration, whether or not the urea water stored in a storage tank is in a stationary state is determined. Only it is in a stationary state, the concentration is detected. The determination of whether or not it is in a stationary state or not is preferably determined by determining whether the vehicle is stopped (S207) and that the period of time TIM that has elapsed after the stoppage has reached a predetermined stationary time TIM1 (S211). The deceleration DCL of the vehicle before stoppage thereof is detected, and the stationary time TIM1 is altered in accordance with the deceleration DCL (S206).

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：用于通过分离两点之间的传热特性检测液体还原剂浓度的浓度传感器设置在用于储存供应到NO x还原催化剂的液体的储罐中。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： 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.
