A fuel is disclosed for use in internal combustion engines, wherein the fuel includes a mixture of at least one alcohol, water, an ignition-improver additive, preferably dimethylether (DME), at least one lubricity agent and at least one anti-corrosion agent. Optionally, the fuel further includes a cetane enhancer, for example Ammonium Nitrate (AN). Optionally, the water is included in a quantity which renders the AN dissolved in the at least one alcohol. Optionally, the DME is included in the range of 0.5-3% by weight. More optionally, the AN is included in a concentration having a range of 0.5% to 10% by weight; more optionally, the AN is included in a concentration having a range of 1% to 5% by weight. Optionally, the at least one alcohol includes methanol. The fuel is optionally capable of being employed via a direct injection of the fuel, in a form of an aqueous solution into engine cylinders. The aqueous solution includes AN and water, which acts as an ignition improver via cetane enhancement of the fuel used. Optionally, the AN and water solution is beneficially mixed in methanol to allow the AN/methanol ratio in be in a range of 5% to 20% by weight. A cost reduction with respect to the use of PEG-dinitrate or Octyl Nitrate based additives is achievable. |
