The 100-MPG Carburetor
It is believed that Charles Nelson Pogue of Winnipeg, Canada, built the first '200-mpg carburetor' in 1935. MPG stands for miles per gallon. From the mechanism of the 200-mpg carburetor, the 100-mpg carburetor was developed. In layman's language, the basic mechanism can be explained. In this carburator air was allowed to pass over the surface of gasoline, which would be absorbed by the engine. In between the fuel tank and the engine, a 'mixing valve' was positioned. The suction created by the downward movement of the piston would push the mixing valve open. The hot air would be able to drive the engine ahead. Along with this, if exhaust heat and radiator water would be used, the fuel would be vaporized better than the standard carburetor.
This method is considered the best for fuel economy. In addition, this concept of 100-mpg carburetor of the 1930's was faulty. The types of gasoline used during the 1930's were very volatile, unlike the gasoline used today. Early carburetors like Pogue, which depended on vaporized gasoline, will not be functional with present day gasoline.
Preheating or warming of fuel has limited value. Therefore, the method of using radiator water or exhaust heat to preheat the fuel to vapor form for extending the mileage, was not very useful.
The radiator's hot water can be used to vaporize the fuel. Present day gasolines do not vaporize completely until they are heated to 450º Fahrenheit. Whereas, water in the pressure radiators can only reach 250º Fahrenheit. Exhaust heat, on the other hand, works a bit differently. Chemical energy is changed into heat by a combustion engine. If this heat cannot produce mechanical movement, it is exhaled out as heat. This heat is the waste energy. This implies that more efficient the engine is the less exhaust heat it produces.
A carburetor's function is to meter and atomize the fuel in the right proportion to air. The use of 100-mpg carburetor is invented for the purpose to improve the fuel economy. In addition, it involves the use of renewable and non-exhaustible substances that helps to a large extend in checking the pollution level in the environment. The fuels used in these carburetors are much more economically viable, if you consider the hike in oil prices.
It was next to impossible to believe that 100-mpg carburetors could be put to commercial and everyday usage. With modern day technology, this myth has been broken. 100-mpg carburetors are waiting next in line to create a revolution in the automobile industry in the 21st century. The automobile manufacturers or the oil giants have not introduced this miracle carburetor for the masses, not because they fear loosing money, but because the common people, that is the buyers do not demand for the change. In addition, the makers have to be far sighted and produce something more efficient like the plug-in hybrid vehicles.
