摘要： PURPOSE: A smoke reducing method of a diesel vehicle is provided to prevent the stop of a starting and the deterioration of the fuel efficiency and to reduce the effect from the pressure change according to an acceleration and a reduction by using a similarity equation. CONSTITUTION: In starting a vehicle, every variable is initialized(S100). The regeneration of diesel particulate filter is checked(S110). An injection control signal is outputted(S155) by deciding an injecting area(S140,S145) after following a driving condition. The stop of an engine according to the pressure change of the diesel particulate filter is prevented(S150,S160). Thereby, the stop of the engine during a driving and the deterioration of the fuel efficiency are prevented.

摘要： PURPOSE: Piezoelectric members are installed in an end and middle part of a catalyst assembly of a catalyst conversion device to measure more accurate temperature. CONSTITUTION: Two piezoelectric member(20) are installed at an end and middle portion of a catalyst assembly(110) to measure temperature of the catalyst assembly. The piezoelectric member has a linear temperature change. The linear temperature characteristic of the piezoelectric member makes it available more accurate input to a voltage measuring circuit(30). If the temperature difference of the piezoelectric member is over a certain limit, a warning signal is outputted.
摘要翻译：目的：将压电元件安装在催化剂转换装置的催化剂组件的端部和中间部分，以测量更准确的温度。构成：在催化剂组件（110）的端部和中部安装两个压电构件（20），以测量催化剂组件的温度。压电元件具有线性温度变化。压电元件的线性温度特性使其能够更准确地输入到电压测量电路（30）。如果压电元件的温差超过一定限度，则输出警告信号。

摘要： PURPOSE: An apparatus is provided to prevent damages of engine by allowing for a bypass of exhaust gas when the function of the DPF is lost. CONSTITUTION: An apparatus comprises a bypass pipe(20) for permitting both ends of a DPF(10) to be communicated with each other and exhaust gas of an engine to bypass the DPF; a bypass valve(30) for opening/shutting the bypass pipe; and an electronic control unit for bypassing exhaust gas of the engine by opening the bypass valve when the function of the DPF is lost. The electronic control unit judges that the DPF has lost its function when the value obtained by dividing the differential pressure between both ends of the DPF by the exhaust flow is higher than the reference value.

摘要： PURPOSE: An air fuel ratio change while detecting a catalyst is prevented for improving an accuracy and reliability of detection. CONSTITUTION: Whether driving conditions of an automobile satisfies a detection starting condition is decided. If the condition satisfies, a fuzzy control valve is closed, and deactivated. A fuel injection learning function of ECU is also deactivated. A deteriorated value of a catalyst is calculated from an output signal of an oxygen sensor, and is compared with a predetermined value to determine deterioration of the catalyst. If the catalyst is decided to be deteriorated, it is alarmed to a driver.
摘要翻译：目的：防止检测催化剂时的空燃比变化，提高检测的准确性和可靠性。规定：汽车驾驶条件是否满足检测开始条件。如果条件满足，则关闭模糊控制阀，并停用。 ECU的燃料喷射学习功能也被禁用。根据氧传感器的输出信号计算催化剂的劣化值，并将其与预定值进行比较以确定催化剂的劣化。如果决定催化剂变质，对驾驶员感到震惊。
