AI Technical Summary

Benefits of technology

[0052] It releases propylene oxide and / or butylene oxide in a precise moment as well as prior to the combustion process, provokes maximal pressure near to the expansion cycle start. Said propylene oxide and / or butylene oxide are produced from component (B), which when compressed at high temperature at the end of the compression cycle, experiences thermal decomposition and releases propylene oxide and / or butylene oxide which, in addition to being produced, burn and help burn the remaining fuel, and also induce a rapid volumetric expansion of the gas that reduces the available space for the combustion of the remaining fuel. Such reduction of the available space for the combustion of the remaining fuel produces some effects in the engine that are similar to increasing the compression ratio. Furthermore, the flame propagation speed is increased, there is a reduction in the needs for lowering the ignition temperature of the alcohol and for having a distillation curve similar to the obtained with commercially available hydrocarbons. Finally, very high combustion efficiency is obtained. It allows low energy content alcohols to be competitive on a “liter to liter” basis with high-energy content fuels, permitting that conventional gasoline or diesel engines could be used without requiring changes in the engine components and that the fuel tank could be filled, totally or partially, and alternating with conventional fuel.

[0053] It acts as a low cost co-solvent that remains in a single phase when the alcohol content is present as the water / alcohol azeotropic mixture. Such single-phase stability is maintained in mixtures with hydrocarbons, even when such mixtures with hydrocarbons are exposed to high ambient moisture, cold weather and limited water filtrations.

[0054] It can be used in engines at lower temperatures and at a lower compression ratio than conventional fuels, allowing the manufacturers to use more economic, lighter and lower cost materials, with a better weight-to-power ratio and with a lower capacity cooling system.

[0055] It produces a colder flame when compared to conventional fuels, it is water-extinguishable, therefore reducing accident risks in vehicles catching fire and allowing the manufacturers to build safer engines that offer more safety in case of an accident.

[0056] It reduces the corrosivity level and produces lubrication properties, when containing additives such as meta-nitrobenzoctadecylamide, nitrobenzoctadecylamide and benzoctadecylamide.

Problems solved by technology

The search for an alcohol based substitute fuel, such as methanol and ethanol, that does not require the modification of the engine, has encountered problems that remain unsolved.

With such lower efficiency, said alcohols are forced to use more gallons per horsepower and their costs cannot be compared in a “liter to liter” basis with other fuels.

This solution would require the modification of engine manufacturing plants around the world and the engines would have a significantly higher manufacturing cost.

When mixed with hydrocarbons they collect water from the air, leading to a phase separation problem in the fuel.

Thus lowering the combustion efficiency.

However, at low speeds the engine knocks, toxic emissions are produced, the octane number is reduced, and the risk of having phase separation remains.

However, higher amounts of toxic emissions are produced, the risk of having phase separation remains and the cost increases.

In addition there is the chance of engine malfunctioning, unless engine modifications are made or some engine components are changed.

However, none of the prior art patents discloses the following:

In addition to being produced, they burn and help to burn the remaining fuel, and also induce a rapid volumetric expansion of the gas.

This expansion reduces the available space for the combustion of the remaining fuel, producing some results in the engine that are similar to increasing the compression ratio.

Using previously performed research and with the analysis of the prior art, it can be asserted that in the present time there are no satisfactory solutions for the above-mentioned problems.
