Motor fuel additive composition

Abstract

Disclosed is an ether containing motor fuel additive composition which synergistically interacts with the ether additive to reduce fuel intake system deposit formation and / or combustion chamber deposit formation, thereby reducing engine ORI and maintaining desired engine performance.

Description

BACKGROUND OF INVENTION [0001] 1. Field of the Invention [0002] This invention relates to a motor fuel additive composition for bulk fuel addition. More particularly, this invention relates to a motor fuel additive composition comprising: (a) a fuel conditioner component comprising (i) a polar oxygenated hydrocarbon compound, and (ii) an oxygenated compatibilizing agent; and (b) an ether, particularly Methyl Tertiary Butyl Ether (MTBE) or Ethyl Tertiary Butyl Ether (ETBE) for use in bulk production of motor fuels while improving performance and decreasing ORI. [0003] Furthermore, this invention relates to a motor fuel additive composition comprising: (a) a detergent component selected from the group consisting of (i) a reaction product component which is the reaction product of a substituted hydrocarbon and an amino compound, and (ii) a succinic anhydride or succinic dibasic acid and (iii) a polybutylamine or polyisobutylamine; and (b) a fuel conditioner component comprising (i) a p...

Benefits of technology

[0010] It is an object of this invention to provide a motor fuel additive for ether containing motor fuels, which is useful in preventing combustion chamber deposit formation. It is a feature of this invention that the additive comprises a fuel conditioner component, which synergistically interacts to reduce combustion chamber deposit formation. It is an advantage of this invention that it both reduces ORI associated with combustion chamber deposit formation.

[0011] It is another object of this invention to provide a motor fuel additive for ether containing motor fuels, which is useful in preventing both fuel intake system deposit formation and combustion chamber deposit formation. It is a feature of this invention that the additive comprises a detergent component and a fuel conditioner component, which synergistically interact to reduce both fuel intake system and combustion chamber deposit formation. It is an advantage of this invention that it both reduces deposit formation in engine fuel intake systems and ORI associated with combustion chamber deposit formation.

[0012] It is yet another object of this invention to provide a motor fuel additive which reduces deposits in engine fuel intake systems and also reduces the amount of ethers required in gasoline while maintaining engine performance.

Problems solved by technology

However, due to the higher cost of ethanol compared to methanol, the ETBE is more expensive than MTBE.

This has led to some complaints by motorists who find the odor unpleasant and in some cases claim the smell has mace them nauseous or caused eye irritation or rashes.

Due to the slightly lower energy content of ethers compared to gasoline, the use of MTBE or ETBE can result in about a 2% increase in fuel consumption.
