Missions of ethanol fueled engine and carcinogenic gases

Ethanol is used widely as a bio-fuel. it is produced from bio-mass (such as corn, sugar cane and sugar beet. research has proved that ethanol improves performance of the internal combustion engine and it considered as an environmental friendly fuel. use of ethanol reduces the emission (co2, co, nox, hc, pm) compared to diesel and gasoline fuel, but this depends on the strategy of operation. however, using ethanol increases the emissions of aldehydes dramatically, especially acetaldehyde and formaldehyde, which are carcinogenic. the purpose of this paper is to study the parameters that affect aldehydes emitted from ethanol fueled engines by using chemkin-pro advanced simulation program.
