摘要： A vapor purge system having a tank isolation valve and a canister vent valve, where each valve includes a latching mechanism for maintaining the valves in an open position, and a diagnostic test is performed on the purge system to prove that each of the valves are functioning correctly. Using latching valves in these applications reduces electricity draw from the battery and reduces electrical interference with integrated pressure sensors. The fuel tank is sealed by the tank isolation valve between the fuel tank and a vapor storage canister, and the canister vent valve provides sealing between the canister and the atmosphere, and controls venting of the canister. The diagnostic test is performed using the tank isolation valve and the canister vent valve under different operating conditions.

摘要： A noise attenuation device for reducing resonance in a natural vacuum leak detector. The device includes a housing, a first connector connected to the housing, and a first fitting connected to the first connector. Also included is a second connector which is connected to the housing on an opposite end of the housing in relation to the first connector, and a second fitting connected to the second connector. A plurality of tubes is disposed within the housing between the first connector and the second connector such that air flows through the first fitting, the first connector, the plurality of tubes, through the second connector and the second fitting. A plurality of flow paths is created by the plurality of tubes, and the plurality of flow paths reduces the turbulence and the pulsation of air flow through the housing, reducing or eliminating resonance in the natural vacuum leak detector.

摘要： A system and method controls a ratio of fuel to gas delivered to an internal combustion engine. Fuel for the engine is stored in a fuel supply. The fuel supply generates fuel vapor that is retained in a canister. The canister is in fluid communication with the engine via a flow path. Hydrocarbon concentration of fuel vapor in the flow path is determined. Pressure drop across a restrictive orifice provided in the flow path is measured to determine a flow rate of the fuel vapor in the flow path. A flow of the fuel vapor through the flow path and to the engine is controlled and injection valves that inject fuel into the engine are controlled so that an amount of fuel injected into the engine is based on the determined concentration of hydrocarbons in the fuel vapor.

摘要： A venturi valve assembly, having a flow tube, an upper port integrally formed with flow tube, a flow cavity disposed within the flow tube, an inlet formed as part of the flow tube such that the inlet forms a part of the flow cavity, an outlet formed as part of the flow tube such that the outlet forms a part of the flow cavity, and a venturi nozzle disposed in the flow tube. Pressurized air flows into the flow cavity from the inlet such that the pressurized air flows around the venturi nozzle. Purge vapor flows into the flow cavity from the upper port, and the flow rate of the pressurized air is increased after flowing around the venturi nozzle, increasing the flow of the purge vapor after the purge vapor is mixed with the pressurized air in the flow tube.

摘要： A valve assembly for an exhaust gas recirculation (EGR) system which provides emission control, regulates flow of exhaust gases, and is suitable for gasoline or diesel applications. The EGR valve assembly is a latching valve assembly which reduces power consumption (i.e., continuous electric draw) from the battery while the valve is either being held open or closed, and reduces electrical interference inherent with integrated position sensors. The valve assembly includes a latching mechanism controlled by an actuator which allows a valve to latch open or closed. The valve may be a single stage valve or a multi-stage valve, which includes a latching mechanism that allows for intermediate open positions, and uses of only a short, single pulse of voltage, to change the state of the valve. The actuator may also be held energized at full extend, maintaining a maximum valve open position, creating additional flow capability of the valve assembly.

摘要： A valve assembly, such as a canister purge solenoid (CPS) having one or more interchangeable components which may be used to reconfigure the valve assembly to have one or more additional vacuum ports. The design of the valve assembly eliminates the need to mold these ports into the intake manifold, simplifying the design of the manifold, and the tooling needed to make the manifold. The direct mount design of the CPS of the present invention includes at least one additional port to serve as an additional vacuum port to be used for any other purpose, such as a PCV valve, brake booster, or the like.

摘要： A turbo purge module includes a purge valve connected between a vapor collection canister and an intake manifold. A venturi nozzle receives pressurized air from the turbocharger, when the turbocharger is operating, to create a vacuum to draw vapors from the canister through the purge valve to an inlet of the turbocharger and the intake manifold to be purged in the engine. A first check valve prevents pressure from the intake manifold from reaching the canister when the turbocharger is operating. A second check valve prevents vacuum pressure from the intake manifold from communicating with the venturi nozzle when the turbocharger is at idle, with vapor from the canister being drawn through the purge valve and the intake manifold to be purged in the engine. The purge valve, venturi nozzle, first check valve, and second check valve are integrated into a single component.
