Benefits of technology

The present invention provides a method for reducing particulate emissions from a direct injection spark-ignition engine by fueling it with a gasoline composition containing a specific type of fuel with low amounts of aromatic hydrocarbons. The gasoline composition should also have a specific temperature range and boiling point range. Using this method can help to significantly reduce particulate emissions from engines and improve air quality.

Problems solved by technology

Current hydrocarbon fuels developed for spark-ignition combustion engines may not be optimised or indeed beneficial for direct injection spark-igntion engines, particularly when it comes to levels of particulate emissions.
However, there is no mention in this document of the use of such a fuel for providing reduced particulate emissions in a direct-injection spark ignition engine.

examples

[0031]The fuel compositions of Examples 1-4 are shown in Table 2 below. Each of these are prepared from the gasoline base fuel having the properties set out in Table 1 below, and for each example the v % of heavy aromatics (aromatics having at least 10 carbon atoms) is adjusted such that it contains an amount of heavy aromatics (C9+) as specified in Table 2 below. Thus, Example 1 contains 0% v heavy aromatics, Example 2 contains 4% v heavy aromatics, Example 3 contains 8% v heavy aromatics and Example 4 contains 12% v heavy aromatics.

Abstract

A method for reducing particulate emissions from a direct injection spark-ignition engine, wherein the method comprises fuelling the engine with a gasoline composition, wherein the gasoline composition comprises a hydrocarbon base fuel comprising not greater than 5% v aromatics of at least 9 carbon atoms, based on the base fuel, a T90 of up to 150° C. and a final boiling point not greater than 190° C.

Description

FIELD OF THE INVENTION[0001]This invention relates to a method for reducing particulate emissions from a direct injection spark-ignition engine.BACKGROUND OF THE INVENTION[0002]There is increasing concern about the environmental effects of particulate emissions from spark-ignition combustion engines, particularly from direct injection spark-ignition engines. This has resulted in a growing demand for motor vehicles that operate with reduced particulate emissions.[0003]Current hydrocarbon fuels developed for spark-ignition combustion engines may not be optimised or indeed beneficial for direct injection spark-igntion engines, particularly when it comes to levels of particulate emissions. It would therefore be desirable to find ways of reducing the particulate emissions from the operation of a direct-injection spark ignition engine.[0004]WO2004 / 113476 discloses gasoline compositions meeting certain parameters whose use as a fuel in a spark ignition engine results in improved stability ...
