Petrol is used as a conventional fuel for many past years. So the dependency on petrol has increased greatly. Due to which depletion of energy sources (i.e. Fossil Fuels- Gasoline and Diesel) have occurred. Therefore there is requirement of hybrid engine, by which dependency on petrol and diesel can be decreased. Now days, people are facing problem of high fuel prices and harmful emission from vehicle which affects directly or indirectly on environment and human health. Aim of our project is to reduce the exhaust emission by running the vehicle on LPG (liquefied petroleum gas)as an alternative fuel for two stroke SI engine. This results in perfect balance in fuel consumption and pollution control which can be optimized in future generation vehicle. Using this concept, two fuels can be effectively transformed to hybrid with increasing fuel efficiency by 30 percent. Two stroke S.I. engines are having poor fuel economy and while using Petrol as a fuel; it emits high hydrocarbons and greenhouse gases.
