Fuel efficiency is amount of work obtained for a quantity of fuel as compared to the energy content of the fuel efficiency specifically considers wasted energy. In autos, fuel efficiency retrofits allow a MPG increase by enhancing the combustion efficiency and speeding up the burn rate more of the carbon fuel is undergoing a complete combustion at a raster rate, therefore by the time the combustion gases are ready to exit the exhaust valves, the gases have slightly more time to cool than with un-enhanced carbon fuel. The most noticeable effect of fuel enhancement is a practical elimination of CO emissions, and a slight increase in the immediate CO2 emission because there is a significant reduction in net carbon fuel requirements, there is an associated NET reduction in CO2 emissions considering the immediate effects!

A marketplace is quickly growing for electrolytic retrofit technologies, among other concepts.

There are many aftermarket retrofit designs, are are currently being sold as "fuel saving devices". Some have a negligible or even harmful effects on fuel efficiency. Others can be beneficial and boost efficiency. Fuel additives are materials which are added to the fuel include tin, magnesium and platinum compounds. The claimed purpose of these devices is generally to improve the energy density of the fuel by virtue of the materials added. Magnets attached to fuel lines have been claimed to improve fuel economy by aligning fuel molecules. Vapour transfer devices claim to improve fuel efficiency by changing the way that liquid fuel converts to fuel vapour. These include "Swirlers" to increase turbulence in the intake manifold and heaters Lean-burn devices change the air-fuel ratio to lean-burn, an engine can increase its fuel efficiency. The main drawback of lean burning is that it greatly increases an engine's pollutant emissions of oxides of nitrogen (NOx). Friction reducing measures reduces fuel consumption. Hardened silicon tires have lower rolling resistance than standard rubber tires. The typical lubricating oil used in engines has decreased in viscosity over the years. However, using a lubricant with lower viscosity than the lubricant specified by a vehicle manufacturer may damage an engine.

Requirements of Gas Mileage Increase

It is not the addition of a fuel enhancer that increases gas mileage. Gas mileage improvement is the direct result of injecting less fuel into the cylinders. Therefore after the addition of a fuel enhancer, the ECU or the carburetor must be adjusted according to the degree of fuel enhancement. If exhaust gas analysis equipment is not available to maximize results, slight air/fuel augmentation can be done by offsetting the Oxygen sensor signal or slightly leaning the carburetor manual adjustments. If exhaust gas analysis equipment is available, optimal results will be achieved by re-flashing custom fuel maps into an ECU or adjusting the carburetor precisely according to the data. This procedure is more difficult and typically requires a custom ECU or a chip with a computer interface, but none the less substantial fuel savings can be achieved simply by offsetting the Oxygen sensor signal or minor tweaks to the carburetor!

Solus Solutions and Technologies - The Cross-Flow Vortex Traps create a series of trapped vortices, oriented vertically on the front face of the heavy truck trailer. The trapped vortices decrease the pressures acting on the front face of the trailer and reduce drag. Fuel savings of between 4 to 5 percent were demonstrated in wind tunnel and road tests.

Turbo Shield - Race cars control undercarriage turbulence by controlling the distance to the pavement, plus the width of the nose piece. This allows the car to be more stable, increase power, and reduces fuel consumption. Attached in front of the axle, the polypropylene Turbo Shield greatly reduces undercarriage turbulence. With significantly less drag, operators of semi-tractors, dump trucks, step vans, motor homes and pickup trucks can see improved mileage of 10-15%.

Fuel Catalysts

Image:Pre-Ignition Catalytic Converter sq.jpg

Directory:PICC Pre-Ignition Catalytic Converter - Better World Technologies presents a catalytic converter replacement that legally pre-treats the fuel for complete combustion, rather than burning what is left over after incomplete combustion. Pre-heating the fuel along a rod turns the fuel into plasma, to burn a wide varieties of fuel efficiently and cleanly.

Image:Supertech devices 95.jpg

Directory:Supertech by United Auto Technologies - Super Tech® is a catalyst device that is immersed in the fuel tank, where it emits infrared and electromagnetic waves. These waves apparently affect the way that the fuel molecules interact with each other, allowing a more favorable combustion of the fuel, resulting in 6% to 12% savings and reduced emissions. Extensive documentation. Skeptic comment.

The Fitch Fuel Catalyst is a maintenance free device which easily installs in the fuel line much like a fuel filter, or directly into the fuel tank. Claims a reduction in emissions with increases of as much as 5% - 10% in fuel economy.

Review of the Fitch Fuel Catalyst

Magazine reviews of the Fitch Fuel Catalyst

Broquet Fuel Catalyst - British product for in-tank or fuel line placement. Cuts emissions by 30 - 50% and improves MPG.

Dynamic Ionizer is a ceramic flow catalyst from Japan made of various radioactive natural ores. It breaks down large ions into smaller ion pairs this improves the bonding efficiency, significantly increasing the output energy from burning. Place in the gas tank and air intake.

Rentar Fuel Catalyst improves combustion on large diesel engines and oil burning furnaces. Explanation of how a catalyst works.

The Energy Group Fossil Fuel Stabilizer - Installs onto the fuel line of any fossil fuel combustion equipment: Virtually complete elimination of exhaust emissions. Boosts overall fuel efficiency from 6% to 30%

Fuel Cat - A more complete and even Combustion gives more power per unit of fuel. If used, the engine performance will be enhanced, using the same amount of fuel, or if saved, better fuel consumption. Typical savings reported by FUEL CAT users is between 8% to 15%. Due to the more complete combustion, both diesel and petrol engines will run more smoothly.

Eco-Systems - The Eco-System is installed inline on your vehicle's fuel line after the fuel filter. When the fuel passes through the unit it creates a catalytic reaction, breaking up the hydro carbon chains in the fuel, causing the vapor pressure to increase. This increase in vapor pressure causes the fuel to burn more completely in the combustion chamber. The more complete burn means lower emissions, increased power, less hesitation and less fuel.

Emissions Technology - Combustion Catalyst Systems use the same principle as a catalytic converter, but attack the source of the problem inside the combustion chamber. A vapour mist of platinum catalyst is injected into the engine through the air intake duct, significantly enhancing the combustion process and reducing fuel consumption up to 15%. See also Emissions Products Intl (US distributor), Emissions Technology UK, and C-tech3000 (UK distributor).

Fuel FX - The Fuel FX Reactor provides on-board refinement to improve the combustion quality of diesel fuel, to reduce fuel consumption by 5 - 15%, increase horsepower and reduce emissions. It is a maintenance free device that is installed on the fuel supply line between the fuel tank and the engine.

Pre-Ignition Catalytic Converter - The PICC replaces you old catalytic converter in the exhaust and fuel is routed through the new one in a counter-flow direction relative to the exhaust. A special "burned-in" rod of cold-rolled steel, cut to the correct length (possibly for a magnetic resonance effect) resides inside the reaction chamber. A phenomenon described as a lightening storm takes place within the reactor, and fuel passing through this "storm" becomes "cracked" into it's elements, also described as plasma, a 4th state of matter. Test cars averaged 3 times mileage running on gasoline alone. A ratio of 50/50 water and gas can double that to 6 times gas mileage. A Directory:Dennis Lee product.
