Claims18
A method of reducing smoke and particulate emissions from an exhaust gas from a spark-ignited reciprocating engine operating on a liquid petroleum fuel, comprising the step of:
- adding a fuel additive to the liquid petroleum fuel, the fuel additive comprises:
- an oil-soluble iron compound:
- and
- an over-based magnesium compound.
The method of claim 1 wherein the oil-soluble iron compound comprises the product of the process of claim 9.
A method of catalyzing combustion of a liquid petroleum fuel in a spark-ignited reciprocating engine, comprising the step of:
- adding an oil-soluble iron compound and an over-based magnesium compound to the liquid petroleum fuel;
- and whereby the engine has improved engine performance, increased engine horsepower produced and increased fuel efficiency.
A method of reducing NOx emissions from hydrocarbon-burning processes comprising the step of:
- adding an additive to a hydrocarbon to be combusted, the additive comprising ferric naphthenate.
An additive for liquid petroleum fuel for use in a spark-ignited reciprocating engine that produced an exhaust gas, the additive comprising:
- a combination of an oil-soluble iron compound and an over-based magnesium compound;
- the combination operable to reduce smoke from the spark-ignited reciprocating engine when an effective amount of the combination is introduced into the liquid petroleum fuel for use in the spark-ignited reciprocating engine;
- and
- the combination further operable to reduce particle emissions from the exhaust gas of the spark-ignited reciprocating engine when an effective amount of the combination is introduced into the liquid petroleum fuel for use in the spark-ignited reciprocating engine.
