Abstract
In today’s world we see that the demand for gasoline and cars keep increasing and one problem which is significantly seen is that we either opt for a fuel which provides higher performance or for a fuel which provides lesser emissions. In this study we aim to provide higher performance and lower emissions by combining two chemicals or octane boosters, namely ethanol and toluene with gasoline and find out its performance and emission characteristics when compared with traditional gasoline and ethanol-gasoline blend. In this study we have made four blends which are PP, E10, E10T5 and E20T5 which are tested against two performance parameters which are Specific Fuel Consumption, Brake Thermal Efficiency with respect to brake power and emissions parameter which are Carbon Dioxide, Carbon Monoxide, Oxides of Nitrogen and Hydrocarbon with respect to brake power as well. In each of these performance and emissions parameters, the blends are compared and we find that E20T5 has the highest performance and E10T5 has the lowest emission.
Highlights
Since the inception of automobiles, spark ignited engines have been a boom in automotive industry and have been capable of converting chemical energy into useful mechanical energy
We can notice that pure petrol (PP) has the highest Specific Fuel Consumption (SFC) followed by 10% Ethanol (E10) and 10% Ethanol with 5% Toluene (E10T5) and see that 20% Ethanol with 5% Toluene (E20T5) has the lowest specific fuel consumption compared to the rest of the blends
This study consists of comparing the ethanol-toluene-gasoline blends with gasoline and ethanol-gasoline blends using the performance and emission parameters and determining which has the best performance and emission characteristics
Summary
Since the inception of automobiles, spark ignited engines have been a boom in automotive industry and have been capable of converting chemical energy into useful mechanical energy. It is one of the most widely used form of engine in the world. The main issue arising from the spark ignited engine being the exhaust emissions which constitutes in the rise of global warming. Octane boosters are used for the purpose of increasing the octane rating of the fuel. These fluids prevent knocking by using anti-knock additives
