摘要： A fuel pumping apparatus for supplying fuel to an internal combustion engine includes a pump having a body and a solenoid operated fuel control device. The current flow to the solenoid is controlled by a control circuit mounted on circuit boards located within an inner casing secured to the body. An outer casing surrounds the inner casing and defines a space which is connected with a fuel inlet, the space communicating with a fuel inlet of the pump. The flow of fuel through the space assists the cooling of the components of the control circuit.

摘要： A fuel return passage is provided between the fuel tank and the float chamber of a carburetor and arranged such that when the temperature of fuel upstream of the float chamber is higher than a predetermined value, the heated fuel in which vapor bubbles are contained is forcedly returned via the return passage to the fuel tank thereby preventing the carburetor from being supplied with such heated fuel.

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： Methods and fuel systems to reduce evaporative emissions of a volatile fuel. A fuel tank contains fuel, a carburetor mixes air with the fuel from the fuel tank, and a plurality of fluid paths route fuel amongst and/or between the fuel tank and the carburetor. A valve actuation device stops flow of fuel in one or more of the plurality of fluid paths and the carburetor is adapted to be drained of fuel during engine shutdown to reduce or prevent evaporative emissions from the fuel system. The carburetor is preferably designed so as to minimize a volume of fuel contained therein.

摘要： An arrangement for limiting the temperature in a carburetor etc. of an engine prevents evaporation of fuel at a temporary stop in the operation of the engine. A receptacle (30) integrated with the carburetor contains a material (31), e.g. paraffin, with a melting point over the normal operating temperature. At a temperature above this melting point the material absorbs melting heat from the environment causing a limitation of the temperature. In this limited temperature the fuel evaporates much slower and a direct start with the remaining fuel after the operating stop is quite possible.
