Investigation on performance of Gasoline engine by changing different types of air filters and spark plugs

The world is facing major problems like conventional fuel crisis, search for best replacement of convention fuel and emission from automobile. Most of alternative fuel technologies are under development right now. The best replacement for petrol and diesel will take time to commercialize at affordable rate.Possible solutions in case of petrol engine to improve performance and reduce emissions are to run engine at leaner or at stoichiometric air fuel ratio and to burn fuel completely inside the combustion chamber. This is possible by providing sufficient pure and clean air without restriction and by providing proper spark at perfect timing with required intensity or energy. These can be achieved doing modifications in air intake system and Spark ignition system. In this investigation different spark plugs and air filters are tested on engine for fuel consumption, power, torque and emission. By measuring and analyzing parameters would lead to the best performance spark plug and the best performance air filter which could replace the conventional one. That best performance air filter and spark plug reduces fuel consumption, improves fuel economy, improves performance of engine and reduces emission without any harm to engine.
