摘要： An engine fuel supply apparatus includes: a fuel chamber provided in a carburetor; a first communication passage for opening the interior of the fuel chamber to the atmosphere; a second communication passage for communicating the interior of the fuel chamber with the interior of a Venturi section; and a passage switching section capable of switching between the first and second communication passages and mechanically connected to the main switch so that it can operate in response to the main switch shifting between an ignition position and a stop position. The passage switching section switches the second communication passage to the first communication passage in response to the main switch shifting from the stop position to the ignition position and switches the first communication passage to the second communication passage in response to the main switch shifting from the ignition position to the stop position.

摘要： An evaporative emissions control system for carburetors used in the internal combustion engines of vehicles, such as motorcycles, has an evaporative emissions control valve attached to the carburetor in the air intake path to the carburetor. The evaporative emissions control valve may be implemented as a sub-assembly add-on or as an integral part of a carburetor or back plate. The evaporative emissions control valve includes a valve, such as a rotatable plate valve, which may be electrically operated by an electrical actuator, such as a dual-wound solenoid actuator. At engine start-up, when the vehicle ignition switch and starter switch are both closed, both windings of the solenoid actuator are energized to provide a strong opening force for the evaporative emission control valve. During steady-state running of the engine, only a single solenoid winding is energized by the power provided through the ignition switch, to maintain the evaporative emissions control valve in the open position. When the ignition switch is opened and the engine is turned off, the evaporative emissions control valve is closed to prevent the release of fuel vapors from the carburetor. A vacuum controlled switch may be used to delay closing of the evaporative emissions control valve after the ignition is turned off for a sufficient time to prevent fuel pooling in the carburetor. A passage may be provided in a shaft of the control valve to selectively control venting of the carburetor fuel bowl, opening the vent during engine operation while closing the fuel bowl vent to prevent evaporative emissions therefrom when the engine is not in operation.

摘要翻译： 用于诸如摩托车的车辆的内燃机中的化油器的蒸发排放控制系统具有连接到化油器的进气路径中的化油器的蒸发排放控制阀。 蒸发排放控制阀可以实现为子组件附件或作为化油器或背板的组成部分。 蒸发排放控制阀包括诸如可旋转板阀的阀，其可以由诸如双卷绕螺线管致动器的电致动器电动操作。 在发动机起动时，当车辆点火开关和起动器开关均闭合时，螺线管致动器的两个绕组被通电以为蒸发排放控制阀提供强大的打开力。 在发动机的稳态运行期间，只有一个电磁铁绕组由通过点火开关提供的电力供电，以将蒸发排放控制阀保持在打开位置。 当点火开关打开并且发动机关闭时，蒸发排放控制阀关闭以防止燃料蒸气从化油器释放。 在点火关闭足够的时间以防止化油器中的燃料积聚之后，可以使用真空控制开关来延迟关闭蒸发排放控制阀。 可以在控制阀的轴中设置通道，以选择性地控制化油器燃料碗的排气，在发动机运转期间打开通风口，同时关闭燃料碗通风口，以防止当发动机不工作时从其中蒸发排放。

摘要： Exhaust gas from an internal combustion piston engine is recirculated through a rich mixture auxiliary intake passage leading to an auxiliary combustion chamber. A valve controls the relative proportions of exhaust gas and air supplied to the auxiliary intake passage, and the valve is controlled by means responsive to suction pressure downstream from the auxiliary throttle valve, and is also responsive to movement of that throttle valve.

摘要： A dual fuel engine includes an engine operable on a gaseous fuel and a liquid fuel and has an electrical power generator. The dual fuel engine also includes a carburetor attached to an intake of the engine to mix air and fuel and connect to a gaseous fuel source and a liquid fuel source. A liquid fuel cut-off connects to the carburetor to selectively interrupt a flow of liquid fuel to the engine. The liquid fuel cut-off is operable in open and closed states such that the liquid fuel cut-off interrupts the flow of liquid fuel when closed. The dual fuel engine also includes controller operably connected to operate the liquid fuel cut-off in the open and closed states, and the controller may be programmed to implement a delay period upon engine startup before closing the liquid fuel cut-off.

摘要： A control system for a turbo charged natural gas engine. A butterfly valve used for fuel control upstream of a carburetor provides non-linear flow response during opening and closing and a flow compensator compensates for the non-linear response. A throttle valve position sensor acts in association with a controller which compares the throttle valve position signal with a predetermined set point and thereby opens or closes the waste gate of the turbo charger which affects oxygen content in the exhaust. A compensator for a throttle valve used with electronic engine controllers is also provided.
