Carbureted air preheater stove

摘要

An internal combustion rotary engine having a can type catalytic converter secured up close to the engine directly to the exhaust manifold is provided with a can type stove closed at only one end that fits over an upper end of the converter and is secured in place without requiring fasteners and is connected at the closed upper end by a tube with the air inlet of the engine's carburetor so that fresh air is directed through the lower open end of the stove and then along the side and over the end of the converter and is heated thereby prior to delivery to the carburetor.
