A fuel for an internal combustion engine includes a C.sub.5 to C.sub.30 dialkoxyalkanoate corresponding to formula (I): ##STR00001## wherein the R.sub.1 group is —H or a —CH.sub.3 group, the R.sub.2 and R.sub.2′ groups are alkyl groups independently selected to have 1 to 9 carbon atoms; and the R.sub.3 group is selected to have 1 to 9 carbon atoms. The compounds described herein may be used as neat fuels or mixed fuels (with diesel, biodiesel, jet fuel, marine fuel or other fuel compounds) in autoignition or spark ignition engines, such as diesel engines, gasoline (spark ignition) engines, MCCI, Homogeneous Charge Compression Ignition (HCCI) engines, or more generally in Low-Temperature Gasoline Combustion (LTGC) engines (using gasoline-like fuels), that have the high-efficiency advantages of HCCI but can operate with some level of charge inhomogeneities. Methods of making these compounds are environmentally friendly and can be done in a continuous manner.

An electrolyte as an additive for internal combustion engines for a production of hydrogen concentrations by a hydrogen generation device. A method of making the electrolyte includes weighing sodium borohydride, sodium hydroxide, and potassium hydride; adding the sodium hydroxide and the potassium hydride to deionized water to make a first composition; mixing the first composition; adding the sodium borohydride to the first composition to make a second composition; adding more deionized water to the second composition to make a basic electrolyte solution; diluting the basic electrolyte solution by adding more deionized water to make a third composition; and adding approximately 3 to 10 mL of sodium borohydride approximately 4.4008 M to the third composition to make an electrolyte having a final concentration sodium borohydride of approximately 0.05947 M.

Provided is a gasoline product containing a combustion improver, and a method for preparing the gasoline product. The combustion improver is added to gasoline to reduce an octane number and thus an ignition point of the gasoline, so that the gasoline product can be used in a compression ignition internal combustion engine. The combustion improver-containing gasoline product is a low-octane number gasoline, and is capable of being ignited through compression by an internal combustion engine having a compression ratio in the range from 12 to 22.
