TI  - THE VARIATIONS OF THE EXHAUST EMISSIONS AT LOW AMBIENT 
TEMPERATURE FOR E10 AND M10 FUELED SI ENGINE
AB  - Biomass fuels are important alternatives to conventional energy sources such as petroleum-based fuels. 
Biomass fuels especially alcohols have been used in passenger cars. Alcohol blends with gasoline constitute a general 
use. Particularly, modification of the engine is not required when using at low rates, like gasohol. Gasohol consists of 
a mixture of gasoline and especially ethanol, and it contains generally 10 percent alcohol. This study deals with the 
effect of the usage of low alcohol containing (10% ethanol or 10% methanol) blends on the exhaust emissions caused 
by an SI engine in the 600 seconds of the engine’s operating period from the cold start-up. According to the experimental 
results, the leaning effect of alcohol on the emissions is clearer in the initial 150 seconds of the experiments. The engineout CO emissions decreased on average 34.5% for E10 fuel and 44.8% for M10 fuel compared to unleaded gasoline. 
Also, in the first 150 seconds, an average reduction of 23.2% E10 fuel and 25% M10 was observed in HC. When it 
comes to the engine-out NO, there were no significant differences by fuel type. Besides, in the study, the tailpipe 
emissions and converter efficiency were examined by heating the catalytic converter without changing other 
experimental conditions. Emissions were significantly reduced in all fuels, while efficiency reached 100%, especially 
for CO emissions.
