摘要： A passive secondary air muffler for a small internal combustion engine. The secondary air muffler may include a venturi device and a catalytic converter. The venturi device may be in the form of a stamped sheet metal insert which, along with the outer muffler housing or shell, forms a secondary or auxiliary air intake device. The venturi device may also be formed from baffles separating an inlet chamber from an outlet chamber of the muffler. The secondary air intake device provides auxiliary or secondary air to the exhaust gas stream exiting the engine upstream of the catalytic converter to improve the efficiency of the catalytic converter. In an exemplary embodiment, the venturi device has a hemispherical cross-sectional shape or a circular cross-sectional shape taken along a plane substantially perpendicular to the direction of flow of the exhaust gas stream.

摘要： An evaporative emissions control system for small internal combustion engines. The system generally includes a charcoal canister and a carburetor with a fuel circuit shutoff valve. The charcoal canister is in fluid communication with the air space above the liquid fuel within the engine fuel tank, and optionally, with the air space above the liquid fuel within the fuel bowl of a fuel bowl-type carburetor. The charcoal canister contains charcoal media which absorbs fuel vapors when the engine is not running. During running of the engine, vacuum within the carburetor induces a flow of atmospheric air through the charcoal canister to purge the collected fuel vapors from the charcoal media, and the fuel vapors pass into the engine for consumption. The carburetor of the engine, which may be either a fuel bowl-type carburetor or a diaphragm carburetor, includes a fuel circuit shutoff valve controlled either by a vacuum signal produced within the engine or by a user-actuated mechanical linkage. The fuel circuit shutoff valve closes the fuel circuit of the carburetor upon engine shutdown to prevent escape of fuel vapors from the carburetor to the atmosphere. In another embodiment, a weir-type carburetor is disclosed which contains a minimal amount of fuel when the engine is not running to reduce or eliminate evaporative emissions.

摘要： The present invention provides an evaporative emissions control system for small internal combustion engines. The fuel tank of the engine includes a filler neck closed by a fuel tank cap which seals the fuel tank in a manner in which air and/or fuel vapors are not permitted to pass between the filler neck and the fuel tank cap. The fuel tank cap includes a first, one-way vacuum relief valve therein which operates to allow atmospheric make-up air to enter the fuel tank to replace a decreasing amount of fuel in the fuel tank during running of the engine, or otherwise as needed. The fuel tank cap additionally includes a second, one-way pressure relief valve having a first cracking threshold which operates to relieve high pressures within the fuel tank. Additionally, the fuel supply line between the fuel tank and the carburetor includes a fuel flow inhibiting or blocking member having a second cracking threshold greater than the first cracking threshold of the pressure relief valve of the fuel tank cap. In operation, fuel vapors are sealed within the fuel tank at all times when the fuel tank cap is closed to prevent fuel vapors from escaping into the atmosphere, and the fuel flow blocking member prevents flooding of the carburetor with liquid fuel if the fuel vapors within the fuel tank build to a high pressure prior to cracking of the pressure relief valve of the fuel tank cap. When the fuel tank cap is removed, a vapor vent valve in communication with the vapor dome of the fuel tank is opened, allowing vapor pressure to be relieved prior to disengagement of the fuel tank cap from the filler neck.
摘要翻译：本发明提供了一种用于小型内燃机的蒸发排放控制系统。发动机的燃料箱包括由燃料箱盖封闭的加油口，所述燃料箱盖以不允许空气和/或燃料蒸汽在加油口和燃料箱盖之间通过的方式密封燃料箱。燃料箱盖包括其中的第一单向真空安全阀，其操作以允许大气补充空气进入燃料箱以在发动机运行期间替换燃料箱中的减少量的燃料，或者根据需要。燃料箱盖还包括具有第一裂解阈值的第二单向压力释放阀，其操作以减轻燃料箱内的高压。此外，燃料箱和化油器之间的燃料供给管路包括具有大于燃料箱盖的减压阀的第一裂解阈值的第二裂解阈值的燃料流量抑制或阻塞构件。在操作中，当燃料箱盖关闭时，燃料蒸汽一直被密封在燃料箱内，以防止燃料蒸汽逸出大气，并且如果燃料蒸汽在其内部燃料蒸汽在燃料箱盖的减压阀开裂之前，燃料箱构成高压。当燃料箱盖被移除时，与燃料箱的蒸汽圆顶连通的蒸汽排放阀打开，允许蒸汽压力在燃料箱盖从加注口分离之前释放。

摘要： An exhaust treatment device is provided for an internal combustion engine of a marine propulsion system. An outer chamber contains a first inner chamber within it and slidably supports the inner chamber. An exhaust inlet conduit directs a stream of exhaust gases from a cylinder of the internal combustion engine directly into the inner chamber. The inner and outer chambers are supported relative to each other to allow relative movement of these two components in response to changes in the differential temperature between the two components. A rail system slidably supports the inner chamber relative to the outer chamber. The exhaust treatment device comprises a liquid cooled housing surrounding the inner and outer chambers. Exhaust gas is directed through the inner chamber and then into the outer chamber at a closed end of the exhaust treatment device. Exhaust gases then flow through the outer chamber to an exhaust conduit of the marine propulsion system.

摘要： An evaporative emissions control system for small internal combustion engines, including a charcoal canister which is in fluid communication with the air space above the liquid fuel within the carburetor of the engine and the air space above the liquid fuel within the fuel tank of the engine. The charcoal canister contains charcoal media, and when the engine is not running, fuel vapors from the carburetor and the fuel tank migrate to, and are trapped within, the charcoal media of the charcoal canister. The charcoal canister may comprise a separate component, or may be integrally formed with an engine component such as the air cleaner, the carburetor, or the body of the fuel tank, for example. During running of the engine, vacuum within the carburetor induces a flow of atmospheric air through the charcoal canister to purge the collected fuel vapors from the charcoal media, and the fuel vapors pass into the engine for consumption. In another embodiment, an evaporative emissions control system including a charcoal canister is provided for an engine which includes a fuel injection system.
