摘要:
The amount of smoke, soot and invisible particulates emitted with the exhaust of engines run on diesel fuel is reduced by incorporating therein an additive consisting of a synergistic mixture of cyclohexane with an oxygenated compound which readily gives up oxygen during combustion.Also disclosed is a method of operating a diesel engine using the fuel of the invention.
摘要:
A filter adapted to connect to an internal combustion engine in relatively close proximity to the engine. The filter will receive a stream of hot exhaust gas immediately as the latter passes from the engine's combustion chambers. The gas then passes through a filter bed disposed within a manifold system incorporated into the filter. The filter bed includes means for stabilizing the temperature thereof within a desired range, regardless of the operating condition of the engine, and the temperature of exhaust gas.
摘要:
Pure methyl-t-butyl ether is used as a cosolvent for hydrous ethanol in gasoline fuel mixtures. The ether solubilizes grain alcohol in all proportions in low aromatics content gasolines.
摘要:
A crude oil composition having a low pour point is prepared by incorporating into a waxy crude oil an effective pour depressant amount of an oil-soluble polymer, such as vinyl acetate-ethylene-propylene or butylene terpolymer or a graft copolymer in which propylene or butylene is grafted onto an ethylene-vinyl acetate copolymer backbone or basic chain. The terpolymer may be added with mixing directly to the heated crude or in hydrocarbon solution such as a solution of the terpolymer in a middle distillate or kerosene. In another aspect, this invention relates to a process for the pipeline transportation of the crude oil compositions previously described.
摘要:
A low pour point fuel oil composition is prepared from a major amount of a high pour point, low sulfur, waxy, residual fuel and a minor amount of low wax, low pour, residual fuel oil by adding thereto from 0.01 to 0.5% by weight of an oil soluble terpolymer such as vinyl acetate-ethylene-vinyl chloride or allyl chloride having a number average molecular weight of about 4,000 to about 70,000. The copolymer may be added either in a water-glycol emulsion or in a hydrocarbon to one of the blend components which has been heated to between about 25.degree. to 150.degree. C. In another aspect, this invention relates to a process for the pipeline transportation of the low pour fuel oil compositions previously described.
摘要:
A novel compound having the following formula: ##STR1## in which R.sup.1 and R.sup.2 may independently represent a hydrogen radical, a hydrocarbon radical having from 8 to 20 carbon atoms, or an alkoxy substituted hydrocarbon radical of from 8 to 20 carbon atoms having at least one alkoxy substituent; R.sup.3 is a hydrocarbon radical having from 8 to 21 carbon atoms or a hydrocarbylamine radical having a molecular weight ranging from 135 to 300;and X and Y are members selected from the group consisting of --H,--COOH,--CN,--CONR.sup.4 R.sup.5,--COR.sup.6, --COOR.sup.7,--C.sub.6 H.sub.5,--NO.sub.2 in which R.sup.4, R.sup.5, R.sup.6 and R.sup.7 independently represent a hydrogen radical or a hydrocarbyl radical having from 1 to 20 carbon atoms;and a detergent and corrosion inhibited fuel composition containing same are provided.
摘要:
A vegetable oil such as soy bean oil, extended by addition of ethanol, may be stabilized against phase separation or haziness in the event of water contamination at pH below 7 by addition thereto of additives such as 2,2-dimethoxy propane.
摘要:
Hydrocarbon fuels heavier than gasoline may be extended by addition thereto of immiscible alcohols in the presence of an acetal or ketal or orthoester co-solvent.
摘要:
Hydrocarbon fuels heavier than gasoline may be extended by addition thereto of ether or ester fuel extenders, soluble in the hydrocarbon fuel, having a molecular weight of about 65-200 and characterized by the presence of at least one methoxy group or ethoxy group. The product is a single-phase mixture which is free of methanol or ethanol.
