Turbocharging of spark ignition engines

Turbochargers are commonly being used on diesel engines for many years. In contrast only a few petrol engines have been turbocharged until recently and it is unlikely that a large fraction of the world petrol engine will be so equipped. Most of the vehicles in the Indian automobile market continue to utilize turbocharged diesel engines compared to gasoline engines. However, experts are of the opinion that turbo growth, in the future would not be confined to diesel sector alone. There would be a tremendous growth in demand of Gasoline downsizing, in next few years. The whole industry is drifting away from naturally aspirated engines & companies like Mercedes & Volkswagen are planning to come up with commercial turbo-charged, downsized gasoline engines. Thus according to experts if automotive sector ,as a whole, is growing at 2%,then turbocharger industry is growing at about 10%,with maximum growth rates coming from turbos incorporated in gasoline engines. The present project aims at analyzing the various benefits associated with "Turbo charging in SI engines" and designing it for future automotive applications.
