Abstract

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.
