Such improved combustion is evidenced by improved fuel mileage and/or improved smoke suppression and/or improved engine cleanliness and/or improved engine efficiency.
Description
This invention relates to improving the combustion of a fuel oil in engines.
Diesel fuel cils are currently employed for the propulsion of vehicles; in particular, automotive vehicles (cars and trucks) railroad engines, and ships. As a result of the current energy problems, there is a need to improve the combustion efficiency of such fuels.
In accordance with one aspect of the present invention, there is provided a combustion improving addi-tive for a diesel fuel oil employed for the propulsion ofvehicles and ships which is comprised of an oil soluble or dispersible calcium compound and an oil soluble or dispers-ible iron compound in an amount effective to improve the combustion of a diesel fuel oil.
In accordance with another aspect of the present invention, there is provided an improved fuel which is a die-sel fuel oil for the propulsion of vehicles or ships having calcium and iron dissolved or dispersed therein in an amount effective to improve the combustion efficiency of such diesel fuel oil.
The fuel oil soluble or dispersible calcium compound may be any one of a wide variety of compounds which are soluble or dispersible in the diesel fuel oil. As represen-tative examples of suitable organic and inor~anic calcium compounds which are soluble or dispersible in the diesel fuel oil, there may be men-tioned:
Calcium Sulfonate Calcium Naphthenate Calcium Carboxylate Calcium Carbonate Calcium ~Iydroxide The fuel oil soluble or dlspersible iron compound may be any one of a wide variety of compounds which are soluble or dispersible in the diesel fuel oil. As repre-sentative examples of suitable organic and inorganic iron compounds which are soluble or dispersible in the diesel fuel oil, there may be mentioned:
Iron ~lapthenate Ferrocene Iron Oxide The selection of a combination of oil soluble or dispersible calcium and iron compounds for a particular diesel fuel oil is deemed to be within the scope of those skilled in the art from the teachings herein. The pre-ferred combination is represented by calcium sulfonate and iron naphthenate.
Applicant has found that the use of a combination of the iron and calcium compound provides an unexpected improvement in combustion efficiency of a diesel fuel oil employed for the propulsion of vehicles, or ships which could not be achieved by using one of the compounds in the absence of the other. Such improved combustion effi-ciency is evidenced by improved fuel mileage and/or improved engine cleanliness and/or improved smoke supp-ression ar.d/or improved engine efficiency.
The fuèl additive includes the iron and calcium compounds in effective combustion improving amounts. In general, the ratio of calcium to iron is fromO.01:1 to 100:1, and preferably 1:1 to 10:1 (weight basis). The selection of an optimum ratio for any particular application is deemed to be within the scope of those skilled in the art from the teachings herein.
The fuel additive is preferably employed as a S liquid additive comprised of the iron and calcium com-pound dissolved in an oil which is soluble in the diesel fuel oil. Any one of a wide variety of oils may be em-ployed, and as representative examples of such oils there may be mentioned: light diesel oil, process oils, naphthenic oils.
Applicant has found that the use of such additives improves the combustion efficiency of the diesel fuel oil as evidenced by reduced smoke emission and/or increased fuel mileage and/or improved engine cleanliness (reduced engine desposits) and/or improved engine efficiency. In addition, the iron and calcium combustion product (iron and calcium oxide) are relatively innocuous in the engine exhaust. As a resutl, improved combustion is obtained with the use of an addltive which will not adversely affect the environment.
The additive is added to the diesel fuel oil to pro-vide a combustion improvement amount of iron and calcium dissolved or dispersed in the diesel fuel oil. In general, improved combustion efficiency is obtained by e~ploying at least 5 ppm of the iron and at least 5 ppm of the calcium in the diesel fuel oil (weight basis). In most cases, the calcium and iron are employed in amounts of at least 50 ppm ~8~
and at least 5 ppm, respectively. The calciur~ and iron are generally not added in an amount in exccss of 100 ppm and 100 ppm, respectively, in that no added beneficial effect is obtained by increasing the amount of addi-tive.
The selection of optimum amounts of the additlve is deemed to be within the scope of those skilled in the art from the teachings herein.
The additive may also include other components which may be normally added to a diesel fuel oil. As represen-tative examples of such materials, there may be mentioned:dispersants and emulsifiers.
Although the additive may be employed for any one of a wide variety of diesel fuel oils, the additive is particularly suited for a light diesel ~uel oil for high speed engines (operating at over 550 rpm), such as in an automotive or railroad engine.
The present invention will be further described with respect to the following examples; however, the scope of the invention is not to be limited thereby:
A mixture was prepared by blending an oil soluble calcium compound (calcium sulfonate) and an oil soluhle iron compound (iron napthenate) at a weig~t ratio of 8:1 respectively. The mixture was diluted with diesel oil to produce an additive containing 4.8% calcium and 0.6% iron. The additive was submitted to an independent s research laboratory ~or smoke suppression testing. The format of the evaluation follows:
1. The testin~ was performed with a Caterpillar lY73 test engine. The base fuel was Howell hydrocarbons Cat l-G2. A Bosch ~FAI~J-68A
Smoke Meter was used to measure smoke density.
