    Abstract: The invention relates to an exhaust gas cooling adapter that is arranged between an exhaust port that is open to a cylinder head of an internal combustion engine and an exhaust manifold, and that includes an exhaust gas flow path through which exhaust gas flows from the exhaust port to the exhaust manifold; and a coolant flow path that is formed inside of an adapter wall surrounding this exhaust gas flow path, and that cools the exhaust gas that flows through the exhaust gas flow path. There is a curved portion in the exhaust gas flow path. Also, a peel inhibiting portion is formed on an inner peripheral surface of the exhaust gas flow path in a region farther toward an inside of the curve than an exhaust gas flow path center line of this curved portion.

    Abstract: An internal combustion engine is provided with a fuel injector which injects fuel into an intake port and exhaust variable valve timing mechanism which changes a valve timing of an exhaust valve. A control device executes early exhaust valve closing control which advances a closing timing of an exhaust valve when conditions for executing early exhaust valve closing control stand. The control device detects an output torque output by an engine body. At the time of deceleration of the engine, even when the condition for executing early exhaust valve closing control stands, execution of early exhaust valve closing control is prohibited when it is predicted that the output torque will become smaller than the limit torque. Thus, due to execution of the early exhaust valve closing control, a large torque fluctuation is prevented from occurring at the time of deceleration of the engine.

    Abstract: During a learning mode period, the fuel correction coefficient is forcibly changed three times from a situation in which no correction is necessary, whereby the fuel injection quantity of each cylinder is forcibly changed three times. A cross-correlation between the estimated air-fuel ratio and the fuel correction coefficient, which are calculated based on the detected value of the air-fuel ratio sensor every 60° CA, is evaluated to learn a deviation of the air-fuel ratio detecting timing from the appropriate value.

    Abstract: An exhaust purifying apparatus purifies an unburnt gas component, such as unburnt hydrocarbon (HC), discharged from an internal combustion engine without fail and prevents the unburnt hydrocarbon from being discharged into the atmosphere. In order to achieve this, the exhaust gas purifying apparatus is provided with a plurality of exhaust passages connected to the internal combustion engine. A joint exhaust passage is formed by merging the exhaust passages and an exhaust gas flows through the joint exhaust passage. An adsorption/desorption unit is provided in each of the exhaust passages for adsorbing an unburnt gas component contained in the exhaust gas that flows through each of the exhaust passages at a temperature lower than a predetermined temperature. The adsorption/desorption unit desorbs the adsorbed unburnt gas component at a temperature equal to or higher than the predetermined temperature. A desorption/adjustment mechanism synchronizes timing of the unburnt gas component desorbed from the adsorption/desorption units into the exhaust purifying units.

    Abstract: A device for purifying exhaust gas includes an HC adsorbent and an exhaust gas purifying catalyst disposed in an exhaust gas passage in this order from the upstream side. The exhaust gas purifying catalyst is provided with an O.sub.2 storage capability, i.e., the exhaust gas purifying catalyst is capable of absorbing oxygen in the exhaust gas when the air-fuel ratio of the exhaust gas is lean, and is capable of releasing the absorbed oxygen when the air-fuel ratio of the exhaust gas becomes rich. When the engine starts, the HC adsorbent adsorbs HC in the exhaust gas. When the temperature of the exhaust gas becomes high, the HC adsorbent releases the adsorbed HC. The device also includes an engine control unit which operates the engine at a lean air-fuel ratio during a predetermined period before the releasing of the HC from the HC adsorbent occurs. Therefore, oxygen is absorbed and stored in the exhaust gas purifying catalyst before the releasing of HC occurs. When the releasing of HC from the HC adsorbent occurs, the air-fuel ratio of the exhaust gas flowing into the exhaust gas purifying catalyst becomes rich due to the HC released from the HC adsorbent. This causes the exhaust gas purifying catalyst to release the absorbed oxygen, and the HC in the exhaust gas is purified by the exhaust gas purifying catalyst using the released oxygen.
