摘要： An exhaust gas purification device comprising a three way catalyst, an oxidizing catalyst and a NOx absorbent which are arranged in this order in the exhaust passage. A rich air-fuel mixture is burned in the combustion chamber, and secondary air is supplied upstream of the three way catalyst so as to make the air-fuel ratio of the exhaust gas flowing into the three way catalyst a rich air-fuel ratio greater than the air-fuel ratio of the air-fuel mixture burned in the combustion chamber. Further, secondary air is supplied upstream of the oxidizing catalyst to make the air-fuel ratio of the exhaust gas flowing into the oxidizing catalyst and the NOx absorbent slightly leaner than the stoichiometric air-fuel ratio.

摘要： An exhaust gas purification device comprising a three way catalyst, an oxidizing catalyst and a NOx absorbent which are arranged in this order in the exhaust passage. A rich air-fuel mixture is burned in the combustion chamber, and the exhaust gas discharged from the engine is initially introduced into the three way catalyst. Secondary air is fed into the exhaust passage between the three way catalyst and the oxidizing catalyst so that the air-fuel ratio of the exhaust gas flowing into the oxidizing catalyst and the NOx absorbent becomes lean.

摘要： An NOx occluding and reducing catalyst is disposed in an exhaust gas passage of an internal combustion engine that operates at a lean air-fuel ratio. When the engine is operating at a lean air-fuel ratio, the NOx occluding and reducing catalyst absorbs NOx in the exhaust gas. To release NOx, the engine is operated at a rich air-fuel ratio so that the exhaust gas flowing into the NOx occluding and reducing catalyst acquires a rich air-fuel ratio. While the engine is operated in a region of moderate lean air-fuel ratios of from the stoichiometric air-fuel ratio to an air-fuel ratio of about 20 at the time when the engine operating air-fuel ratio is changing from a lean air-fuel ratio operation to a rich air-fuel ratio operation, an electronic control unit (ECU) of the engine injects secondary fuel, that does not contribute to combustion, into the cylinders of the engine through the direct cylinder fuel injection valves in the expansion stroke or the exhaust stroke of the cylinders, so that the exhaust gas flowing into the NOx occluding and reducing catalyst acquires a rich air-fuel ratio. This prevents unpurified NOx from flowing out of the NOx occluding and reducing catalyst at the time when the engine operating air-fuel ratio is changed.

摘要： An engine includes a double barreled carburetor. A sensor mounted to the exhaust system detects the concentration of a component in the exhaust. A control unit, based on a signal from the sensor, dispatches a control signal to an air bleed control valve to vary its resistance. Primary and secondary path systems lead from the outlet of the air bleed control valve and respectively supply primary bleed air into the fuel which is being supplied into the primary barrel of the carburetor and secondary bleed air into the fuel which is being supplied into the secondary barrel of the carburetor. A one way valve is fitted in the secondary path system so as to allow air flow only towards the secondary barrel, and not away therefrom. Thus, when both barrels are opened, bleed air is sucked in to the primary barrel through the primary path system, and also bleed air is sucked in to the secondary barrel through the secondary path system past the one way valve; but, when only the primary barrel is opened, bleed air is sucked in to the primary barrel through the primary path system, but no bleed air is sucked in to the secondary barrel through the secondary path system, and the one way valve prevents reverse flow of air from the secondary barrel through the secondary path system and thencefrom into the primary path system towards the primary barrel.

摘要： A control system for an internal combustion engine including a direct cylinder fuel injection valve for directly injecting the fuel into a cylinder of an internal combustion engine. The main fuel that burns in the cylinder is injected in the latter half of the compression stroke of the cylinder, and the secondary fuel which is the ineffective fuel that does not burn in the cylinder is injected in the latter half of the exhaust stroke main fuel and the secondary fuel air-fuel ratio mixture around the spark plug. When the secondary fuel is injected, the exhaust valve is opening, and the fuel that is deflected is all discharged out of the cylinder through the exhaust port. Therefore, the ineffective fuel supplied by the secondary fuel injection does not remain in the cylinder, and the output torque does not change in the combustion of the next cycle.

摘要： Start catalysts (SCs) having an O2 storage function are disposed in an exhaust gas passage of an internal combustion engine, and an NOx occluding and reducing catalyst is disposed in the exhaust gas passages downstream of the SCs. NOx in the exhaust gas is absorbed by the NOx occluding and reducing catalyst when the engine is in operation at a lean air-fuel ratio. When NOx is to be released, the engine is operated at a rich air-fuel ratio so that exhaust gas having a rich air-fuel ratio flows into the SCs and into the NOx occluding and reducing catalyst. An electronic control unit (ECU) executes the secondary fuel injection that does not contribute to the combustion in the expansion stroke or in the exhaust stroke of each cylinder by using a direct cylinder fuel injection valve at the time when the engine operating air-fuel ratio is to be changed from a lean air-fuel ratio operation to a rich air-fuel ratio, so that exhaust gas having a rich air-fuel ratio flows into the SC and that oxygen stored in the SC is released. At the time of changing over the air-fuel ratio, therefore, the air-fuel ratio is changed from the lean side to the rich side without delay, eliminating such an occurrence that NOx is released from the NOx occluding and reducing catalyst without being purified at the time of changing the air-fuel ratio.
摘要翻译：具有O 2储存功能的起始催化剂（SC）被设置在内燃机的排气通道中，并且NOx吸留还原催化剂设置在SC的下游的排气通道中。当发动机以稀薄的空燃比运转时，废气中的NOx被NOx吸留和还原催化剂吸收。当要释放NOx时，发动机以丰富的空燃比运转，使得具有浓空燃比的废气流入SC并进入NOx吸留和还原催化剂。电子控制单元（ECU）通过在发动机工作空燃比（ECU）中使用直接气缸燃料喷射阀来执行对膨胀行程或每个气缸的排气冲程中的燃烧无贡献的二次燃料喷射从稀空燃比操作变为浓空燃比，使得具有浓空燃比的废气流入SC，并且释放存储在SC中的氧。因此，在空燃比变化的时候，空燃比从稀侧变为富侧无效，消除了NOx从NO X吸留还原催化剂释放而不被净化的情况在改变空燃比的时候。

The main fuel that burns in the cylinder is injected in the latter half of the compression stroke of the cylinder, and the secondary fuel which is the ineffective fuel that does not burn in the cylinder is injected in the latter half of the exhaust stroke, the main fuel and the secondary fuel being injected toward a cavity formed in the top surface of the piston. The main fuel that is injected is deflected by the cavity to form a charge of a combustible air-fuel ratio mixture around the spark plug. When the secondary fuel is injected, the exhaust valve is opening, and the fuel that is deflected is all discharged out of the cylinder through the exhaust port.

摘要： A vehicle control system configured to judge a vehicle behavior or a driving preference of a driver based on acceleration of the vehicle including at least longitudinal acceleration. An acceleration value used in the judgment is obtained on the basis of a weighted detection value of the actual longitudinal acceleration of the vehicle, and a weighted parameter which is varied by an operation to increase a driving force of the vehicle executed by the driver. A weight on the parameter is reduced in case a weight on the detection value of the longitudinal acceleration is increased, and the weight on the parameter is increased in case the weight on the detection value of the longitudinal acceleration is reduced.
