摘要： PROBLEM TO BE SOLVED: To provide a urea water injection amount control device capable of facilitating reduction in excess or deficiency in supply amount of NH3 by improving estimation accuracy of an NO/NO2 ratio.
SOLUTION: The ratio of NO to NO2 (NO/NO2 ratio) flowing into an NOx reduction catalyst of SCR (selective catalytic reduction) is estimated based on a conversion rate of NO2 where NO is oxidized by oxygen and is converted to NO2 in an oxidation catalyst of DOC (diesel oxidation catalyst) and a conversion rate of NO where NO2 is converted to NO as carbon is oxidized by NO2 in DPF (diesel particulate filter). Based on the NO/NO2 ratio estimated in this manner, the amount of urea water injected from an injection valve is controlled.

摘要： PROBLEM TO BE SOLVED: To solve the problem that existence of clogging in an upstream side pipe 40a can not be judged in a differential pressure detection device 40 detecting differential pressure between an upstream and a downstream of DPF (Diesel Particulate Filter) provided in an exhaust gas passage 32 of a diesel engine 10. SOLUTION: An estimation value (operation history formula estimation value PM1) of PM (Particulate Matter) accumulation quantity is calculated based on cumulative value of new accumulation quantity of PM at each time estimated from an operation condition of the diesel engine 10. An estimation value (differential pressure formula estimation value PM2) of PM accumulation quantity is estimated based on differential pressure detected by the differential pressure detection device 40. Time until differential pressure detected by the differential pressure detection device 40 converges to actual differential pressure is extended if clogging exists after completion of transition during which exhaust gas volumetric flow rate of the diesel engine 10 increases. Degree of this extension is judged based on the differential pressure formula estimation value PM2 and the operation history formula estimation value PM1. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To effectively prevent the occurrence of partial rapid combustion in a particulate filter (DPF) 32 to collect exhaust gas particle (project manager) 32. SOLUTION: In an ECU51, a present accumulation amount of exhaust gas particles based on the operation state of an internal combustion engine, such as the differential pressure of a DPF32, is computed. When the present accumulation amount exceeds a preset upper limit value, in addition to control through which forced regeneration to regenerate DPF32 by forcibly burning and removing accumulation exhaust gas particles is allowed, if as a result of the temperature of exhaust gas in the DPF32 being compared with a reference temperature, it exceeds the reference temperature, it is decided that it is during natural regeneration and thereafter it is decided that it is not during natural regeneration, and when an accumulation amount of the exhaust particles is reduced to a value lower than a lower limit value, control through which forced regeneration is executed and completed is added. Since this constitution enables approximate complete removal of accumulation exhaust gas particles, it is dissolved before dispersion of accumulation in the DPF32 becomes excessive, and it can be avoided that rapid combustion occurs at a superfluous accumulation part in the DPF32.

摘要翻译：要解决的问题：有效地防止微粒过滤器（DPF）32中部分快速燃烧的发生，以收集废气颗粒（项目经理）32。解决方案：在ECU51中，当前累积量计算出基于内燃机的运转状态（例如DPF32的压差）的废气粒子。当当前累积量超过预设的上限值时，除了通过强制再生以强制燃烧再生DPF32以及去除积聚废气颗粒的控制之外，如果DPF32中的排气的温度被比较，则允许参考温度超过参考温度时，判断为在自然再生期间，此后判断为不是在自然再生期间，并且当排气颗粒的堆积量降低到低于增加下限值，执行强制再生的完成控制。由于这种构造能够大致完全去除积聚废气颗粒，所以在DPF32中积聚分散之前溶解变得过大，并且可以避免在DPF32中的多余积聚部分发生快速燃烧。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide an exhaust emission control device for an internal-combustion engine capable of preventing a catalyst from deteriorating and a particulate filter from being damaged resulting from a steep rise of the temperature of the particulate filter at the time of steep deceleration etc. and precluding a degradation of the fuel consumption by regenerating at one time a large quantity of PM upon depositing it. SOLUTION: The end on the exhaust gas outflow side of the particulate filter 1 installed in an exhaust pipe 2 of the internal-combustion engine E is formed in a deep plug structure, where a heat absorption part 4 is provided. As the heat absorption part 4 has a greater heat capacity than the other areas, absorption and dispersion of the combustion heat can be made even in case rapid chain reactions of PM are generated, and it is possible to suppress the temperature rise downstream of the particulate filter 1 likely to become high temperature.

摘要： PROBLEM TO BE SOLVED: To improve safety and prevent deterioration of fuel economy by accurately estimating SOF accumulation quantity and SOOT accumulation quantity and performing regeneration at appropriate timing. SOLUTION: DPF 3 is installed in an exhaust gas passage 2 of a diesel engine 1 to collect exhaust particulate. Accumulation quantity of SOF which is organic solvent soluble composition and accumulation quantity of SOOT which is solid carbon composition out of exhaust particulate composition accumulated on the DPF 3 are estimated respectively. When accumulation quantity of SOF reaches SOF removal execution accumulation quantity M1, temperature of the DPF 3 is raised to relatively low SOF combustion temperature or higher, when accumulation quantity of SOOT reaches SOOT removal execution accumulation quantity M2, temperature of the DPF 3 is raised to relatively high SOOT combustion temperature or higher, to execute SOF removal process. Rapid combustion of SOOT caused by SOF combustion can be prevented by executing removal process before SOF gets excessive. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To precisely find out the PM accumulated amount of a particulate filter (DPF). SOLUTION: In the calculation of a PM amount executed by an ECU 51, an accumulation characteristic for regulating an increase characteristic that pressure loss is increased according to the PM accumulated amount is descried with a first characteristic line whose inclination becomes small after exceeding a transition point and extending from an initial point to the transition point and a last characteristic line extending from the transition point, and an accumulated amount ML is calculated from pressure loss ΔP based on the accumulation characteristic. When a PM accumulation state is entered into the region of the last characteristic line, a forcible transfer processing is executed at a predetermined timing, and the accumulation characteristic used for calculating the PM accumulated amount is changed over to a limit accumulation characteristic described with a straight line passing through the initial point and having the same inclination as the last characteristic line. Thereby, the limit accumulation characteristic is effected which is not required to consider a change in the accumulation characteristic caused by combustion, use is prohibited on a small amount side where the estimated accuracy of the PM accumulated amount in the limit accumulation characteristic is not enough, and high accuracy is realized.

摘要： PROBLEM TO BE SOLVED: To provide a malfunction diagnosis device for an exhaust emission control system having a simple hardware construction for diagnosing the malfunction of the exhaust emission control system such as the quality of a reducing agent. SOLUTION: The malfunction diagnosis device includes conversion rate calculating means S14, S27 for calculating a NOx conversion rate, and quality diagnosing means S28, S32 (diagnosing means) for diagnosing the quality of urea water (reducing agent) in accordance with a degree of the deviation of an conversion rate ηstart at current start of an internal combustion engine from an conversion rate ηlast calculated by the conversion rate calculating means at previous stop of the internal combustion engine. From the fact that there should be no great change of the conversion rate between before and after an engine stopping period unless the quality of the urea water is changed during the engine stopping period, the quality of the urea water (the malfunction of the exhaust emission control system) can be diagnosed without the need for a sensor to detect the concentration of the urea water, in accordance with a degree of the deviation of the starting conversion rate ηstart from the stopping conversion rate ηlast.

SOLUTION: After engine starts (S10), an estimation value of a PM deposition amount in the DPF stored in a memory in stop of the engine is called (S20), current differential pressure is measured (S30), and a current PM deposition amount is estimated from the differential value (S40).
