Abstract
An anti-wear compression ignition fuel for use in diesel engines comprising (1) a monohydroxy alkanol having from 1 to 5 carbon atoms, and (2) a wear inhibiting amount of a straight chain aliphatic primary amine, e.g. oleyl amine. Optionally, said fuel composition may also contain an ignition accelerator such as an organic nitrate. It has recently been disclosed in Brazilian Patent Application No. P17700392 that alcohols, such as methanol and ethanol, can be substituted for conventional petroleum derived diesel fuels for burning in diesel engines, when used in combination with an ignition accelerator, such as ethyl nitrate or nitrite. Reportedly, the addition of alkyl nitrate or nitrite accelerators to the alcohol achieves a level of auto-ignition sufficient to operate in diesel engines. Unfortunately, these fuel compositions, devoid of any petroleum derived products, are notably deficient in lubricity or lubricating properties with the result that engine wear from the use of these fuels in internal combustion reciprocating diesel engines is a serious problem. Of particular concern are wear problems associated with the fuel injector mechanisms used in such engines. Wear problems ha…
