摘要： Systems and methods for draining fuel from a carburetor of a combustion engine can include a first control valve in communication between a fuel source and a fuel chamber of a carburetor and a second control valve in communication between the fuel chamber of the carburetor and a drain reservoir. The first and second control valves can be coupled and operable such that, upon disengagement of the engine, the first control valve can be closed to block a supply of fuel to the fuel chamber, and the second control valve can be opened to connect the drain reservoir to the fuel chamber, which can operate to draw liquid fuel from the fuel chamber into the drain reservoir. The fuel can then be moved from the drain reservoir into a fuel storage tank, where it can be stored until needed by the carburetor.

摘要： The present subject matter relates to arrangements and uses for engine speed governors. In particular, an automatic idle system for a small engine can include an engine speed governor for connection to a small engine with a governor shaft rotatable in response to a speed of the engine. A governor linkage can include a first portion for connection to the governor shaft and a second portion for connection to a throttle control of the engine, the first portion being movably connected with or to the second portion. An actuator can be connected to the second portion of the governor linkage, the actuator being movable in response to a load on the engine to move the second portion relative to the first portion. In this configuration, when the engine is in a low-load state, the second portion can be moved relative to the first portion toward a throttle-closed position.

摘要： A fuel system for a carburetor that supports operation of an engine includes a body with a bore, a fuel source communicated with the bore and from which fuel is supplied to the bore for delivery to the engine, a drain unit and a control. The drain unit is communicated with the fuel source to selectively receive fuel from the fuel source and has a fuel chamber and an actuator operable to vary the volume of the fuel chamber. The control is communicated with the actuator to permit fuel flow from the fuel source to the fuel chamber when the engine is shut down and to cause fuel to flow from the fuel chamber to the fuel source prior to starting the engine.

摘要： A method of operating an engine is disclosed, which includes determining a peak power condition for the engine, measuring a temperature associated with the engine at said peak power condition, comparing the temperature measured with a previously determined temperature associated with a known peak power condition of the engine, determining an offset value based on the comparison made in step, controlling at least one of an air-fuel mixture delivered to the engine or ignition spark timing based on said offset value. Various engine fuel delivery systems, carburetors, fuel injection and control systems also are disclosed.
