摘要： PROBLEM TO BE SOLVED: To prevent DPF13 from being cracked by the sudden combustion of post-injected fuel due to the adhesion of the post-injected fuel to DPF13 in an engine performing the post-injection of fuel to burn soot by raising the temperature of DPF13. SOLUTION: An oxidation catalyst 12 is disposed in an exhaust gas passage 11 on the upstream side of DPF13. When the temperatures of the oxidation catalyst 12 and DPF13 are low, the post injection timing is advanced to burn the post-injected fuel in a cylinder to prevent the post-injected fuel from flowing into DPF13, and an exhaust emission temperature is increased to rapidly increase the temperatures of the oxidation catalyst 12 and DPF13. After the temperature of the oxidation catalyst 12 is increased, a post injection timing is retarded and the post-injected fuel is fed to the oxidation catalyst 12. The temperature of DPF13 is increased by utilizing a catalyst reaction heat there. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To reduce NOx while reducing soot in exhaust gas of a diesel engine. SOLUTION: A swirl port 4 and a swirl adjusting port 14 are formed, and an intake port 4a of the swirl port is larger than an induction port 14a of the swirl adjusting port. A swirl valve 18 is formed to the swirl adjusting port, and an opening degree of the swirl valve is made small. Even when a swirl ratio becomes high, average flow rate coefficient can be secured high. Under a driving condition, in which the temperature inside a cylinder is likely to be high, the opening degree of the swirl valve is made large, so as to heighten the average flow rate coefficient.

摘要： PROBLEM TO BE SOLVED: To make a proper quantity of exhaust emission back-flow when after- injection control is performed to discharge NOx from NOx trap material in an engine for which the quantity of exhaust emission back flowing is feedback- controlled based on the change of the concentration of the oxygen in exhaust emission to obtain a target air-fuel ratio. SOLUTION: During the control of after-injection, the quantity of exhaust emission back-flowing is increased by lowering a target value A/Fref for feedback-control, on the other hand, during a specified period T1a from the start of the after-injection control, feedback control is restrained to reduce the quantity of feed back operation.
