Project Summary

An internal combustion engine converts stored chemical energy in a fuel to useful mechanical energy. Now there are certain problems also while using bio-fuels which include depleting fossil fuel resources, emissions and environmental concerns and economic issues. Now there is a solution for this problem.Internal combustion engines are being replaced by electronic cars that completely run on batteries and they don’t have any sort of negative impact on environment. These modern electronic engines are noty yet known emit any sort of harmful gases. But there are some problems in this case too that includes range charging stations for these types of cars that cost a lot and this new technology will require new infrastructure Another alternate includes using hydrogen in internal combustion, but citing numerousi issues it was unable to be considered as a viable replacement. This leads us to biofuels. Biofuels can ber produced in numerous ways to meet the demands, have cleaner emissions from the combustion process, and are said to have higher performance parameters. In our study we will theoretically and experimentally investigatet these claims, on various blends of butanol and ethanol and compare them to performance and emission parameters of pure gasoline. These tests will be performed on test bench facilities of the Airforce Labs.

Project Objectives

This is an experimental study on the performance and emission parameters of an internal combustione engine run on various Bio-fuel blends of ethanol and butanol. The motivation behind this study is top prove the credibility of more sustainable fuel options that will run on the existing infrastructure. In this project we aim to analyze and compare effects Biofuel Blends on a gasoline engine to see the impact on performance, efficiency and emission parameters. We aim to validate the trends of biofuel blended gasoline engine referring to previous studies. Finally we aim to find the best optimum blends for efficientand effective performance parameters on the internal combustion engine.

Project Implementation Method

The tests will be performed on the test bench under constant conditions for all fuel types. Some of these include range of RPMs, stoichiometric air fuel ratios, operating temperatures, fuel rate.

The fuels types are as follows:

1. 100% pure gasoline

2. 5-20% blends of ethanol and gasoline

3. 5-20% blends of butanol and gasoline.

For the acquirement of fuels, Ethanol has been manufactured locally by a team who we were introduced to by our supervisor. Butanol was purchased from a distributor. The fuels will be evaluated for performing parameters. Key parameters include break power, torque, thermal efficiency, volumetric efficiency, fuel consumption. Furthermore the fuels will be tested for emissions. Percentage of presence of substances including carbon dioxide, carbon monoxide, unburnt hydrocarbons, oxides of nitrogen and sulfur will be recorded.The results will be compared between the various blends of the two biofuels while also being compared to traditional gasoline fuel's performance.

Benefits of the Project

Provide an environmentally friendly, high performing and economical alternate to fossil fuels for the automotive industry. This will replace fossil fuels without the need to modify the existing infrastructure. This means all previous technology will stiol be compatible and no changes are required. It will be cost effective, saving fuel import costs on the country. The most important point would be replacing

Technical Details of Final Deliverable

Experimental and theoretical findings will be published in our report. We aim to prove that these alternate fuel options are most suited for our country, given the conditions. We will suggest optimal fuel type and blend based on performance, emissions and economical parameters.
