Abrégé

Disclosed is an enhanced fuel, a method of producing such enhanced fuel, and method of using such enhanced fuel for operating internal combustion engine. The fuel includes a mixture of at least one alcohol, water and ammonium nitrate (AN) as a cetane enhancer. The water is included in a quantity which renders the ammonium nitrate dissolved in the at least one alcohol. The fuel further contains dimethylether as an ignition-improver additive, at least one lubricity agent and at least one anti-corrosion agent.

Abrégé

Disclosed is a method of increasing efficiency of a combustion system, which runs with alcohol fuels, by injecting a controlled quantity of a fuel additive. The method includes using one of a single injector tip for pre-mixed alcohol fuel and fuel additive or individual injector tips for the alcohol fuel and the fuel additive. The fuel additive includes a mixture of organic compounds of which at least one organic compound includes at least one nitrate molecular group. The method further includes injecting the pre-mixed alcohol fuel and fuel additive or the alcohol fuel and the fuel additive individually into one or more combustion chambers of the engine block. The method also includes controlling a quantity of the fuel additive by a control arrangement associated with a temperature sensor, and controlling a flow-rate of the alcohol fuel by a power control adapted to controller an output power from the engine block.
