An attempt has been made in this project to use alternative fuel in two stroke Gasoline engine. Our fore most aim in selecting this project is to use non conventional fuel against conventional fuel which is becoming scarce and costly now days. With this air is less polluted than conventional fuels. It is also good with regard to economical considerations.
 
In our project we have installed LPG fuel system to two stroke vehicle where in we can use both gasoline and LPG. The alternations made to install LPG in the vehicle are discussed. LPG from storage tank comes to the adjustable regulator through a primary delivery valve fitted at the mouth of the LPG cylinder.
