    摘要： A forward flow region in which forward intake air currents are produced and a reverse flow region in which reverse intake air currents are produced are formed in the throttle bore of a throttle body 3 included in an internal-combustion engine, and the boundary between those regions extends below a throttle valve 5. A fuel vapor control system for an internal-combustion engine has a purge tube 13 joined to the throttle body 3 to supply fuel vapor into the throttle body 3 and is provided with an opening 22 which acts as a purge port. The opening 22 is positioned at a distance from the inner surface 21 of the throttle body 3 defining a throttle bore on the boundary between the forward intake air currents and the reverse intake air currents. Fuel vapor jetted through the opening 22 of the purge tube 13 into the throttle bore flows toward an intake manifold 2, diffusing into both the forward intake air currents and the reverse intake air currents from the boundary between the intake air currents. Accordingly, the fuel vapor is distributed evenly through the intake manifold 2 to the cylinders, so that increase in the difference in air-fuel ratio between the cylinders can be suppressed. The purge port can relatively easily be formed, because the purge tube 13 provided with the purge port is fitted closely in a bore formed in the throttle body 3.

    摘要： A vaporized fuel control apparatus according to the present invention is provided in an internal-combustion engine at least including a plurality of cylinders and each cylinder having a fuel injector, an intake tube mounted to the cylinders, a fuel tank, and a canister connected to the fuel tank. The vaporized fuel control apparatus includes a purge valve and an electronic control unit for controlling the opening/closing of the purge valve. The purge valve is provided in a purge passage connected between the canister and intake tube, the canister being filled by an absorbing material to absorb a fuel vaporized from the fuel tank. The electronic control unit controls an amount of purged gas flowing into the intake tube by controlling the opening/closing timing and the duty ratio of the purge valve in such a way that the purge valve is opened at a timing when a stroke of a particular cylinder reaches the same stroke at a next cycle in synchronization with an engine rotational speed, and an amount of the fuel supplied to the particular cylinder is reduced in accordance with an amount corresponding to an inflow amount of the purged gas.

    摘要： An air-fuel ratio control system for a gas-fueled engine which is capable of achieving the combustion in a target air-fuel ratio to surely purify an exhaust gas through an exhaust purification catalyst. In the air-fuel ratio control system, a three-way catalytic converter is placed in an exhaust pipe of the engine and an O2 sensor is located on the upstream side of the three-way catalytic converter. The O2 sensor comprises an element, and an atmosphere side electrode is formed on an inner surface of the element while an exhaust gas side electrode is formed on an outer surface thereof. The exhaust gas side electrode is coated with a catalyst layer which can remove hydrogen through a catalytic reaction. A control unit of the control system controls a fuel supply quantity by a gas injector using a feedback correction coefficient on the basis of the output of the O2 sensor, thereby reducing the deviation between an air-fuel ratio measured by the O2 sensor and a target air-fuel ratio.

    摘要： The exhaust emission containing large and small particles, discharged from an exhaust port of a cylinder No. 1 of an engine during a first exhaust stroke collides with a first adsorbent opposed to the exhaust port, so that some of the small particles of HC enter a connecting gas passage. Since the latter is not connected to a second adsorbent for a cylinder No. 3 in which a second exhaust stroke consecutively occurs, the exhaust gas discharged from the first cylinder can be easily introduced in the first adsorbent and in the connecting gas passage. When the cylinder No. 4 changes to an exhaust stroke, the exhaust gas discharged therefrom is introduced in the connecting gas passage through the corresponding adsorbent to move the HC remaining in the connecting gas passage toward the first adsorbent. Thus, the HC is adsorbed again by the first adsorbent and little is discharged into the air. Consequently, the HC adsorbing efficiency can be enhanced.

    摘要翻译： 在第一排气冲程期间从发动机的1号气缸的排气口排出的含有大颗粒和小颗粒的废气排放物与与排气口相对的第一吸附剂碰撞，使得一些HC的小颗粒进入 连接气体通道。 由于后者不连接到其中连续发生第二排气冲程的3号气缸的第二吸附剂，所以从第一气缸排出的废气可以容易地引入到第一吸附剂和连接气体通道中。 当气缸4变为排气行程时，排出的废气通过相应的吸附剂被引入到连接气体通道中，以使残留在连接气体通道中的HC向第一吸附剂移动。 因此，HC被第一吸附剂再次吸附，并且很少被排放到空气中。 因此，可以提高HC吸附效率。
