摘要： A throttle body may have a main bore for supplying a fuel and air mixture to an engine. A throttle valve head may be received in the main bore and movable between idle and wide open positions to control fluid flow through the main bore. A main fuel outlet and a boost venturi may open to the main bore and a flow directing feature may alter the velocity and/or direction of fluid flow in the main bore relative to the fuel outlet or boost venturi. The flow directing feature may be carried by the body, the throttle valve head, or the boost venturi.

摘要： A throttle body assembly for a combustion engine includes a throttle body having a pressure chamber including a supply of liquid fuel, and a throttle bore with an inlet through which air is received. A throttle valve is carried by the throttle body with a valve head movable relative to the throttle bore. A metering valve is coupled to the throttle body, and has a valve element that is movable between open and closed positions. A boost venturi is located in the throttle bore and has an inner passage that is open at both ends to the throttle bore. The boost venturi has an opening through which fuel flows into the inner passage when the valve element is in the open position, wherein fuel flows from the pressure chamber to the metering valve under the force of gravity or under a pressure of less than 6 psi.

摘要： A dual fuel engine includes an engine operable on a gaseous fuel and a liquid fuel and a switch to change operation of the engine between gaseous fuel and liquid fuel. 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 attaches to the carburetor to interrupt liquid fuel upon actuation of the switch from liquid fuel to gaseous fuel.

摘要： Methods and systems are provided for introducing water into an intake manifold of an internal combustion engine. In one example, the system may include a water container, a water inlet for inputting water into the intake manifold, and a throttle valve that is arranged between an intake manifold inlet and the internal combustion engine, with the water container arranged at a higher point than the water inlet and the water inlet opening into the intake manifold downstream of the throttle valve. A switchable valve is arranged in fluidic connection with both the water container and the water inlet, with the result that it can enable or interrupt the introduction of water into the intake manifold and also create a Venturi effect at the water inlet, which draws water from the water container.

摘要： A two-cycle engine 1 is provided and has a cylinder in which is formed a combustion chamber that is delimited by a piston which, via a connecting rod, drives a crankshaft rotatably mounted in a crankcase. The engine has an air duct that communicates with a transfer channel, and a mixture channel via which fuel/air mixture is drawn into the crankcase. At least a portion of the length of the mixture channel is separated from the air duct by a dividing wall that extends in a direction of flow of the air. The dividing wall separates the channels from one another in such a way that the ratio of the cross-sectional area of the mixture channel to the cross-sectional area of the air duct is approximately in the range of 0.5 to 1.9.

摘要： This invention describes systems and methods for mixing two fluids. A first fluid, usually fuel, can be passed through a primary passage that typically leads to a carburetor or other inlet to a combustion engine. A second fluid, usually air, can be mixed with the first by introducing it to the primary passage through an inlet located upstream in the primary passage. The mixture of fluids can then be further emulsified by passing it over a plurality of obstructions, such as a threaded interior surface of the primary passage, located within the primary passage downstream of the inlet.

摘要： A mixer for a gas fueled engine uses a venturi through which a fuel nozzle opens into an air inlet path at a narrowest portion of the venturi in a substantially parallel orientation relative to the flow of inlet air in the air inlet path to reduce the mixture loss, and an air nozzle opens into the air inlet path at an expanding portion of the venturi in a substantially parallel orientation relative to the flow of the inlet air to reduce the ventilation resistance caused by a boundary layer and to make a uniform mixture of the gaseous fuel and the air.
