Abstract
In this paper the influence of changes in ethanol concentration in gasoline-alcohol blend on the concentrations of aldehydes and hydrocarbons emitted from a spark-ignition automotive engine is described. Results of the exhaust gas analysis with E0, E5, E10, E25 and E50 blends tested in a car meeting the Euro 5 emission standard are presented. It was found that an increase of the ethanol concentration in the fuel blend leads to an increase in the acetaldehyde concentration in the exhaust gas. TD-GC-FID/MS analysis of exhaust gases collected on two different, complementary sorbents (Carbograph 1TD, Tenax TA) allowed for identification of the large number of hydrocarbons.
Highlights
Hundreds of organic and inorganic compounds, many of which have a negative influence on the environment and human health, are created during the combustion of fuel in the engine
This study focuses primarily on determining the impact of increased ethanol content in the fuel on the emission of aldehydes, mainly acetaldehyde resulting from the incomplete oxidation of ethanol
The exhaust gas was collected onto two different, complementary sorbents: Carbograph 1TD and Tenax TA
Summary
Hundreds of organic and inorganic compounds, many of which have a negative influence on the environment and human health, are created during the combustion of fuel in the engine These include, among others, oxides of nitrogen (NOx), carbon monoxide (CO), and hydrocarbons (HC), including aromatic hydrocarbons and aldehydes. One of the potential ways to reduce emissions of harmful compounds in vehicle exhaust is the use of alternative fuels, or fuels with the addition of bio-components Alcohols such as methanol (MeOH) and ethanol (EtOH) are added as oxidisers (low concentrations of alcohol) or alternative fuels (mixtures with high concentration of alcohol). Jednak prowadzone obecnie prace badawcze w krajach Unii Europejskiej i USA określają te związki jako planowane do limitowania ich emisji w przyszłych przepisach Euro 7, obok innych związków do ograniczania w spalinach silników spalinowych, jak: NO2, N2O, NH3.
