Abstract
A method for heating intake air and a carburetor of a dead, cold internal combustion engine of a first vehicle which uses an apparatus that heats the cold engine with energy supplied by a second vehicle having a running internal combustion engine. The apparatus is placed within the air filter housing above the carburetor of the cold engine. The apparatus includes a housing configured to be positioned within the air filter housing of the cold engine. The apparatus housing includes a source of heat such as a plurality of fin tubes that are fluidly connected to the cooling system of the running engine. The tubes transfer heat from the heated coolant to air surrounding the fin tubes. In a modified form of the invention, electrical heating wires are used to heat the air. The heated air is then mixed with fuel in the carburetor and used to start the cold engine. In a further preferred embodiment, a fan is also included within the apparatus housing for moving air through the heating elements to increase heat transfer efficiency.
