The fuel efficiency of automobiles and efficiency of gas powered engines has gained much interest in recent years. Fuel prices have been rising, there is growing concern about the environment and global warming, and the U.S. is dependent on foreign countries for its oil.
Of course almost everyone is aware of these problems, but many people
do not know that there is technology out there that can help lessen the
magnitude of these troubles. This technology is called vaporized fuel
injection. There are several different versions of this technology
and many of the inventors have patents, but they are not being put into
cars or other engines on a mass scale yet. One of the inventors who
have a patented design for a certain vaporized fuel injection, called
fuel vaporizing and mixing, is Gerald Rowley. Gerald Rowley is the
inventor of the Vapster system. The Vapster system works like most of
the other fuel vaporization systems, but it seems to have the most
coverage and the most testing time with it. This is because Rowley put
a prototype in a Mazda Miata and has run many tests on it. The test
results have shown about a 40% increases in fuel mileage and less
pollution.
The fuel vaporizing and mixing system, Vapster, works by preheating the gasoline sent to the engine to about 350 degrees Fahrenheit, which is enough to turn it into a vapor before it enters the combustion chamber. (Brown) Currently only about 15% of the energy from the gas in your car gets used to move your car. That leaves about 85% as wasted energy, of which about 62% is heat energy. (Fueleconomy.gov) Vaporized fuel injection systems use much of this wasted heat energy to do useful work by converting the fuel into vapor. To heat the fuel to this temperature, the Vapster system draws heat from the exhaust. The fuel is gravity-fed into a stainless steel chamber which absorbs a lot of heat form the exhaust. (Demory and Morse)
The engine cannot just start up using the Vapster system. The engine must first warm up to the temperature needed to vaporize the fuel. To do this, the engine must run using the existing fuel delivery system until it is hot enough for the exhaust heat to be able to vaporize the fuel. Once the optimum temperature is achieved, the original fuel system is shut off, and the Vapster system takes over. The vaporized fuel is then pressurized to 2-4 psi. This pressurization is achieved using an external, battery-operated pump, and it forces the gas vapor to move into the engine through the throttle body and into the cylinder. A small rise in horsepower can actually be made by increasing the pressure in the pump. (Demory and Morse)
The reason that Vaporized fuel injection works to achieve better gas mileage and less pollution is interesting and makes a lot of sense when you think about it. Vaporized fuel injection systems can achieve much better gas mileage because they burn the gasoline more completely. In cars today, the main reason for inefficiency is that the gas is not burned completely. By vaporizing the fuel, it can burn more completely. When vaporized, the fuel will mix more readily and easily with the air in the combustion chamber and will offer more surface area for the combustion reaction to occur. (Chu)
The Vapster system is very beneficial to the environment for the reason that it uses less air and oxygen than a normal car does. When running on vapor, the airflow into the engine is usually decreased by about one third to one half the amount of airflow in a normal car. (www.freeenergynews.com) This is great for the environment because less air is being used in the burning process and thus less carbon dioxide is emitted. The Vapster system works to reduce the amount of air sent into the combustion chamber by incorporating a ball or butterfly valve on the existing carburetor. This ball or butterfly valve is only used when the engine is running on vapor. As stated before the car must use the original fuel system to heat the engine enough to be able to vaporize the fuel. During this time the engine operates under its normal airflow, and reduces airflow only when the Vapster system kicks in.
The only drawback with the Vapster system is that currently it must be used in engines that have a fixed RPM. So this system would be ideal for hybrids, generators, tractors and farm equipment, boats, and other fixed RPM engines. There is a slowing mechanism built into the patent design that works by introducing misted water into the system, but this component requires much further testing and development. (Freeenergynews.com ) If this system of misted water is developed more, the system should be able to run effectively in non fixed RPM engines.
This year, the Vapster system was successfully tested by a test engineer from Applied Consumer Services INC. The test engineer witnessed four mileage tests in Rowley's 1993 Mazda Miata, which had one of his patented Vapster systems in it. In this test the car ran on one gallon at a time until it stopped. The car was driven on a turnpike so that the road would be level for the entire trip. The gasoline used for all four tests was Shell 89. For each test the temperature of the engine block, the engines RPM's, the wind direction and the driving speed (65 mph), were recorded so a comparison could be made later. The test engineer concluded for the results of the four control and four experimental tests that the Vapster system averaged a 27.4% increase in fuel economy. (Applied Consumer Services Incorporated) The data from this test can be seen in Table 1.
Lessening the consumption of fuel and pollution is very important today and will only get more and more important in the future. Vaporized fuel Injection looks like a very promising means of lessening gasoline consumption and pollution. Gerald Rowley's Vapster system is working very well and proving its value in the results of the various tests it has undergone. Hopefully in the near future some automobile or engine company will invest in further development of this invention and start putting Vapsters in its engines on a mass scale.
