Abstract:
Disclosed herein is a method for increasing the maximum operating speed of an internal combustion engine operated in a low temperature combustion ignition mode, the method comprising operating the engine with a fuel composition comprising (a) gasoline having a Research Octane Number (RON) greater than 85 and (b) one or more cetane improvers.
Abstract:
A method of introducing additives to an air intake system of an engine in order to overcome one or more of the various problems created by formulation of additives in fuels. The method controls at least one of the amount, aerosol particle size and timing of introduction of additives based on information relevant to operation of the engine. The introduced additives form an air-additive mixture and are carried by the airflow in the air-intake system to the combustion chamber of the engine. Another aspect of the invention is an additive introduction system that includes one or more containers for additives, a control system for determining at least one of the amount, aerosol particle size and timing of introduction of the additives, and a device to introduce the additives into the air intake system under the control of the control system.
Abstract:
A fuel composition comprises glycerol and a combustion improving agent. The glycerol may be obtained from a renewable biological source and before mixing with the combustion improving agent may be treated by mixing with an inorganic acid and removing water and methanol under normal or reduced pressure, and removing solid material. Other aspects of the invention provide a method of making a fuel composition and methods of combusting glycerol fuel compositions.
Abstract:
The present invention relates generally to a composition and method for decreasing the emissions from combustion of fuel that contains biodiesel, where the composition contains at least one ignition accelerator and at least one plant extract or synthetic component similar to a portion of a plant extract. The ignition accelerator is preferably a peroxide, for example, di-tert-butyl peroxide. The composition may optionally contain meadowfoam oil or jojoba oil. The composition may also enhance the lubricity of the fuel that contains biodiesel.
Abstract:
The present invention relates to an "alcohol based fuel and/or biofuel composition" having as a main feature the capacity of totally or partially substituting traditional fuels, such as gasoline and diesel, in conventional internal combustion engines. In addition, the "alcohol based fuel and/or biofuel composition" can be used for the total or partial substitution of burning oils.
Abstract:
There is described a fuel composition which is substantially free of alkoxylated compounds and is substantially free of long-chain alkyl alcohols having at least 6 C atoms, and contains at least 95 % by volume of a hydrocarbon-based fuel and 0.1 to 5 % by volume of an additive of the formula (I); R-CO-NR R (I) in which R is a saturated or unsaturated, linear or branched alkyl radical having 6 to 21 C atoms; and R and R , which may be the same or different, each represent a hydroxyalkyl radical having 1 to 4 atoms.

Abstract:
Disclosed is a liquefied gas fuel, which can reduce emissions of air pollutants, such as black smoke, particulate matter, NOx and SOx in an exhaust gas of a compression ignition engine. The liquefied gas fuel comprises liquefied petroleum gas added with a radical generating agent, a lubricity improving agent and liquid hydrocarbon, or dimethyl ether added with the lubricity improving agent.
Abstract:
The present invention is directed to combustion catalysts fuel additive compositions, modified fuels exhibiting improved combustion efficiency when modified by an effective amount of the combusiton catalysts; and processes for operating internal combustion engines utilizing the modified fuels. Selected Group IIA and Group IIB metal oxides, hydroxides, and organic peroxides, EMP and TBH, which when introduced at ppm levels, into fuels utilized in the internal combustion engines increases efficiency and performance, improves exhaust emissions and reduces carbon deposits and mileage. The combustion catalysts introduction to the internal combustion engine cylinder can be through a suspension within the fuel or as a particulate or liquid suspension introduced through the engine air intake system.
Abstract:
Diesel fuels, particularly low sulfur diesel fuels, contain additives which increase the lubricity in the fuel and reduce the amount of smoke in the exhaust. These additives are esters having a viscosity of 3.0 cSt to 20.0 cSt at 100 DEG C and a smoke index of at least 75.
