摘要： PROBLEM TO BE SOLVED: To restrain an increase in a discharge quantity of unburnt fuel and even misfiring, while restraining a discharge quantity of NOx, when an operation state of an internal combustion engine becomes a transitional operation state, in an exhaust emission control system of the internal combustion engine having a supercharger and an EGR device.
SOLUTION: Target supercharging pressure and a target EGR gas quantity are calculated on the basis of the operation state of the internal combustion engine (S102). When actual supercharging pressure does not reach the target supercharging pressure when the operation state of the internal combustion engine becomes the transitional operation state (S104), an EGR gas quantity is controlled in a quantity less than the target EGR gas quantity (S106 and S107).

摘要： PROBLEM TO BE SOLVED: To restrain filter temperature from dropping when the operation condition of an internal combustion engine is in a transitional state during a filter-regeneration control in an exhaust emission control system of the internal combustion engine provided with a filter in the exhaust passage in order to collect PM in the exhaust gas. SOLUTION: In the filter regeneration control, filter temperature is raised to a command temperature by supplying unburned fuel to a catalyst having function of oxidation. If the engine operation condition is in a transitional state in the filter-regeneration control, the amount of unburned fuel to be supplied to the catalyst is corrected to be increased more than a reference supply amount. In this case, if the engine operation condition is in a transitional state to raise the engine-load, the amount of increase correction of unburned fuel is determined on the basis of the rate of increase in the intake air-flow of the engine (S105, S106). If the engine operation condition is in a transitional state in which the engine-load is reduced, the amount of increase correction of the unburned fuel is determined on the basis of temperature of the catalyst (S110, S111).

摘要翻译：要解决的问题：在内燃机的运行状态在设置有过滤器的内燃机的废气排放控制系统中的过滤再生控制期间处于过渡状态时，要抑制过滤器温度下降排气通道，以便在废气中收集PM。解决方案：在过滤器再生控制中，通过向具有氧化功能的催化剂供给未燃烧的燃料，将过滤器温度提高到指令温度。如果发动机运转状态在过滤器再生控制中处于过渡状态，则向催化剂供给的未燃烧燃料的量被校正为比基准供给量多。在这种情况下，如果发动机运转状态处于过渡状态以提高发动机负荷，则基于发动机的进气风量的增加率来确定未燃燃料的增量校正量（S105 ，S106）。如果发动机运转状态处于发动机负荷减小的过渡状态，则基于催化剂的温度来决定未燃烧燃料的增量校正量（S110，S111）。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To oxidize and remove PM accumulated on a filter, while inhibiting degradation of exhaust gas emission and fuel-economy in an exhaust emission control system of an internal combustion engine provided with the filter in the exhaust gas passage of the engine for collecting PM in the exhaust gas. SOLUTION: In the exhaust emission control system, a catalyst having the function of oxidation is placed in the exhaust gas passage upstream of the filter, or it is carried on the filter. The filter is regenerated by supplying unburned fuel to the catalyst. If the adhesion of unburned fuel on the passage reaches at least a specified amount in the filter-regeneration control, an exhaust gas temperature-raising control is started so at to raise the temperature of exhaust gas by raising the engine load. Thereafter, the exhaust gas temperature-raising control is stopped in the timing when the amount of adhesion of unburned fuel on the passage, which increases again upon stop of the exhaust gas temperature-raising control, becomes at most the specified amount of adhesion when the filter regeneration control is stopped.
