摘要： 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.

摘要： The emission control system of the present invention removes the small amounts of polluting gases released from various parts of the automobile. These polluting gases are released from, for example, fuel oozing out from connections of the pipes in the fuel system, lubricating oil oozing out from engine body, and solvents and adhesives remaining in the interior and exterior parts of the automobile. In the emission control system of the present invention, collectors and suction pipes are provided. The collectors are disposed at the parts of the automobile from where the polluting gases are released in such a manner that the collectors enclose these parts. The suction pipes connect the respective collectors to an intake nose of an air cleaner disposed in an intake air passage of the engine. Therefore, the polluting gases released from various parts of the automobile are drawn into the engine through the respective suction pipes before they diffuse into the atmosphere, and are burned in the engine. Thus, according to the present invention, the polluting gases released from various parts of the automobile are prevented from diffusing into the atmosphere.

摘要： A moisture adsorbent (32) for adsorbing moisture in exhaust gas and an NOx adsorbent (34) for adsorbing NOx are disposed in a bypass passage (30) for bypassing an exhaust passage (16) of an internal combustion engine (10). When an adsorption operation to the NOx adsorbent (34) is executed, inflow of the exhaust gas to the bypass passage (30) is allowed until the moisture amount that flows into the water adsorbent (32) reaches an allowable moisture inflow amount. The allowable moisture inflow amount is determined based on a residual moisture amount before the starting of the adsorption operation in the moisture adsorbent (32). The residual moisture amount in the water adsorbent (32) can be determined based on the temperature of the moisture adsorbent (32) at the immediately preceding execution of the purge operation.

摘要： An exhaust purifying apparatus for an internal combustion engine includes a catalyst that purifies exhaust gas from the engine, a first passage that allows exhaust gas to flow from the engine to the catalyst, and a second passage that allows exhaust gas to flow from the engine to the catalyst. The first passage includes an accelerated cooling portion whose cross section is designed so that a relatively large quantity of heat is released from the exhaust gas in the first passage, and the second passage has a cross section designed so that a relatively small quantity of heat is released from the exhaust gas in the second passage. The apparatus further includes a flow amount controller that controls amounts of exhaust gas flowing through the first and second passages, such that the amount of exhaust gas flow through the first passage is made larger than that through the second passage when the temperature of exhaust gas emitted from the engine is to be lowered by a relatively large degree before reaching the catalyst, and such that the amount of exhaust gas flow through the second passage is made larger than that through the first passage when the temperature of exhaust gas emitted from the engine is to be lowered by a relatively small degree before reaching the catalyst.

摘要： An air-fuel ratio control device comprising an electric air bleed control valve which controls the amount of air fed into the fuel passage of the carburetor so that an air-fuel ratio becomes equal to the stoichiometric air-fuel ratio. The degree of opening of the air bleed control valve is increased as an electric current fed into the air bleed control valve is increased. Fuel vapor is fed into the intake passage from the canister. When the electric current fed into the air bleed control valve is increased and reaches a predetermined upper limit due to the supply of purge gas, the current fed into the air bleed control valve is instantaneously increased by a fixed amount.

The degree of opening of the air bleed control valve is increased as an electric current fed into the air bleed control valve is increased. Fuel vapor is fed into the intake passage from the canister. An auxiliary air is also fed into the intake passage via an electric auxiliary air bleed control valve. When the supply of fuel vapor to the intake passage is started, if the electric current fed into the air bleed control valve increases and reaches the upper limit, the auxiliary air bleed control valve is opened. As a result, the electric current fed into the air bleed control valve is lowered and can move up and down so that an air-fuel ratio becomes equal to the stoichiometric air-fuel ratio.

摘要： A variable venturi-type carburetor comprising a vacuum chamber, connected to a venturi portion of the carburetor, and a suction piston actuated in response to a change in vacuum in the vacuum chamber. A fuel passage is formed in the carburetor and is open to the intake passage of the carburetor. The suction piston has a needle extending through the fuel passage. An air bleed passage is connected to the fuel passage. When the level of vacuum in the intake passage becomes smaller than a predetermined level, the amount of air fed into the fuel passage from the air bleed passage is reduced, and the vacuum chamber is caused to be open to the atmosphere.
