摘要： A control unit for an internal combustion engine can activate a three-way catalyst at the early stage and can lessen the deterioration of the exhaust in an internal combustion engine such as HC, CO, and NOx, etc. from the exhaust gas when starting. The control unit for an internal combustion engine is provided with the three-way catalyst and HC adsorbent on an exhaust side. The control unit alternately controls the A/F between a rich state and a lean state in order to quicken the activation of the three-way catalyst when the internal combustion engine starts.

摘要： A control method of an internal combustion engine with which braking force while reducing the speed of the motor vehicle can be established by generating pumping loss effectively by using a variable valve mechanism enabling to control arbitrarily the open-close timing and the lift amount of air intake and exhaust valves of the engine. When the break step-on force detection means detects a step-on force on a brake and an operation of the anti-lock brake system is selected, at least one of the intake valve or the exhaust valve is made close, another one not closed of the intake valve or the exhaust valve is made open once in a single revolution of the engine while a piston moves from a top dead center to a bottom dead center, and a lift of the valve is controlled to be a designated value.

摘要： The engine disclosed features an engine cylinder provided with an air intake valve, an injector having a fuel injection port which is directed towards an interior of the engine cylinder, and a control unit which is connected to the air intake valve and to the injector, the control unit effecting changes in the air intake amount by controlling the degree of opening of the air intake valve, and, also, controls the air/fuel ratio by changing the amount of fuel supplied by the injector. The engine also has an exhaust valve in the engine cylinder such that the control unit controls the intake valve and the exhaust valve so that an opening period of the intake valve is overlapped with an opening period of the exhaust valve at least when the opening period of the intake valve is maximum. The period of the overlap is longer when a relatively large amount of air is required than when a relatively small amount of air is required. According to such a scheme, the amount of the air can be changed by the lift of the intake valve. By changing the lift, the overlap with an exhaust valve is also changed. During the high-output or power operation, the period of overlap between the exhaust valve and the intake valve is made longer. When engine torque decreases to a level lower than the target engine torque, the air amount is adjusted by the cam or the throttle valve.

摘要： An air intake system for an internal combustion engine uniformly distributes the fuel-air mixture in the cylinder, and concentrates the mixture in the vicinity of an ignition plug in the cylinder by selecting the direction of supply of sprayed fuel, thereby improving ignitability of the mixture at the time of lean-burn operation. The system produces tumble flow in the cylinder for accelerating combustion and provides lean-burn operation, thereby suppressing consumption of the fuel and reducing the amount of exhaust gas. The fuel is injected by a fuel injection valve and collides with an intake valve, before being atomized. The atomized fuel flows into the cylinder from the side of the intake valve closer to the fuel injection valve. On the other hand, high-velocity air flow from bypass passages enters the cylinder from the side of the intake valve closer to the ignition plug, so as to produce tumble flow in the cylinder.
