Researchers to Harness Exhaust, Save Gas

by

 

The Department of Energy has issued a challenge: increase fuel economy 10% by converting the heat lost through a vehicle’s exhaust pipe into power:

In an internal combustion engine, only about a quarter of the total energy from gasoline is used to actually turn the wheels, while 40 percent is lost in exhaust heat and 30 percent is lost through cooling the engine. That means about 70 percent of the available energy is wasted, according to GM.

Researchers studying thermoelectrics, the study of using heat differences to create electricity, have developed a system that will install a metal plate around the exhaust pipe that can capture the heat lost through the exhaust fumes. Currently, General Motors and BMW claim prototypes of their products will be available in 2009.

GM said their prototype could increase fuel economy in a Chevy Suburban by five percent, a one-mile-per-gallon improvement, and will be even more efficient in smaller vehicles. If GM can meet the DOE’s challenge, the auto maker’s researchers say a 10% improvement could save more than 100 million gallons of gas per year on just their vehicles alone.

    Here is some info to help gain 7% – 15% in gas milage, proven and guaranteed. Below is some information on the MPG-CAPS. Test have been done with other news agencies with their back-up to the savings

    MPG-CAPS™ change the surface heat absorption characteristics of the metal. The fuel and air mixture produces energy in the form of heat that creates expansion that drives the piston down, and the film inhibits the transfer of radiant heat. This directly results in higher combustion temperature, greater expansion, and more power. The second benefit the MPG-CAP™ film provides is a polished surface effect that allows more even distribution of the fuel. It can be compared to the beading of water on a polished paint job. The micro film attracts the liquid fuel resulting in better fuel distribution that shapes the charge to yield more power.

    The third benefit of the film is by serving as a catalyst precursor to react with the catalyst component in the MPG-CAPS™ themselves. The active compounds of the MPG-CAPS™ in combination with the heat in the cylinder cause a catalytic reaction that promotes better disassociation of chemicals and better burn. The catalytic reaction is also exothermic and produces heat. Altogether, these three benefits result in a total of 30 to 40% more expansion in the cylinder with an equal amount of fuel.

    Another factor to be considered is the ability of the film created by the MPG-CAPS™ to inhibit the build-up of harmful deposits. This is particularly important in view of the effects that the EPA regulations have had on the automobile industry. In order to comply with EPA mandates to lower emissions, fuel manufacturers have removed lead and added oxygenates to fuel. The repercussion is the building of harmful deposits that tend to soak up fuel and cause performance problems. Decreasing the extent of those deposits is yet another benefit of our product.

    Lastly, and perhaps most importantly of all, is the reduction of emissions resulting from the use of MPG-CAPS™. The catalytic process found in catalytic converters on exhaust systems is started in the firing cylinder, which reduces the formation of nitrogen oxides (NOx). The work done by the converter is reduced, and life of the converter is extended.

    Extensive scientific testing has revealed many positive effects of FFi products, and none that are negative. Distributors and customers have the added security of a world wide insurance policy that covers any possibility of engine damage. There is every reason to be confident in the abilities of the MPG-CAPS to make a favorable difference in your world.
