摘要： PROBLEM TO BE SOLVED: To reduce NOx while reducing soot in exhaust gas of a diesel engine. SOLUTION: A swirl port and a swirl adjusting port are formed as intake ports, and DPF 36 for collecting soot in the exhaust gas and an oxidation catalyst 37 for oxidizing NO in the exhaust gas into NO2 and supplying it to the DPF 36 are installed to an exhaust passage 35. When the DPF 36 is in an active condition for generating an oxidation reaction of soot with NO2 , the swirl adjusting port is closed to heighten intake flow rate. Thereby, the temperature inside a combustion chamber is heightened, so as to promote generation of NO, increase the volume of NO2 supplied from the oxidation catalyst 37 to the DPF 36, and regenerate the DPF 36.

摘要： PROBLEM TO BE SOLVED: To stably ensure NOx absorbing performance without causing smoke increase in an exhaust purification device equipped with a catalyst convertor, composed of an NOx absorber for absorbing the NOx in an oxygen excessive atmosphere while releasing the NOx absorbed due to the lowering of oxygen concentration, on the exhaust passage of a direct-injection diesel engine for directly injecting and supplying fuel to a combustion chamber in a cylinder. SOLUTION: When the NOx absorbing quantity of an NOx absorbent is estimated (S3), and the quantity becomes a set value or more, an air-fuel ratio is controlled in a nearly theoretical air-fuel ratio (S6), and also fuel is halved into early injection at a suction stroke initial period and the latter period injection at the compression stroke final period, to be injected (S7-S11). When an engine is not in a high-load operation region, a suction throttle valve is closingly actuated to reduce suction air quantity (S5-S12).

摘要： PROBLEM TO BE SOLVED: To eliminate catalyst poisoning and to effectively purify NOx, even when sulfur is contained in fuel and exhaust emission purifying catalyst is poisoned by sulfur compound. SOLUTION: In an exhaust gas purifying system of a diesel engine 1, NO in exhaust gas is oxidized into NO2 by an Ag-based catalyst within a first catalytic converter 15, and NO2 is reduced into N2 by a Pt-based catalyst within a second catalytic converter 16 and is purified. When the Ag-based catalyst within the first catalytic converter 15 is supposed to be poisoned by sulfur compound such as SO2 or SO3, an EGR ratio is increased by an ECU, thereby an exhaust gas temperature is increased, succeedingly a catalytic temperature is increased and CO is generated. By this CO, sulfur component combined with the Ag-based catalyst is dissociated, the catalyst poisoning is eliminated and NOx is effectively purified.

When an engine is returned to steady operation after acceleration, the catalyst side switching valve 11 is gradually opened while the by-pass side switching valve 12 is gradually closed by the control of a control unit 31. In the accelerating state, the by-pass side switching valve 12 is fully opened while the catalyst side switching valve 11 is closed so as to supply the supercharger 6 with the exhaust gas not cooled by the catalyst.

摘要： PURPOSE:To surely conduct scavenging of a combustion chamber so as to enhance volume efficiency by offsetting an opening portion of an exhaust port from a cylinder axis to the peripheral side so as to rise obliquely upward nearly in the tangential direction. CONSTITUTION:In an upward flow, uni-flow type on the peripheral surface of a cylinder 1 and an exhaust port 7 opens on the ceiling surface 3 of the cylinder 1. In this case, the opening portion of the exhaust port 7 is oriented obliquely upward nearly in the tangential direction at a position offset to the peripheral side from the axis 10 of the cylinder. Accordingly, swirl in the circumferential direction formed in the upper part of the cylinder 1 propagates over the whole region within the cylinder 1, to generate at lateral eddy. Consequently, 8 or in the upper peripheral portion of the cylinder 1 is engulfed in the lateral eddy and rapidly discharged into the exhaust port 7 so that scavenging with the combustion chamber 4 is performed certainly to enhance the volume efficiency.
