Professor, Automobile Department, KJIT, Vadodara, Gujarat, India 2 Automobile Engineering Students, KJIT, Vadodara, Gujarat, India ABSTRACT To start with, a study on the effect of turbocharger on a single cylinder 2-stroke engine is made. The design and installation of turbocharger in a engine is available in this work. We have design and fabricated a prototype of turbocharger which was implemented in 2-stroke engine, In which the efficiency of the engine will be increased. volumetric efficiency of a S.I. Engine will be increased and proper scavenging will be done by providing combustion chamber with maximum amount of air. Keywords : Turbocharger, 98.2cc, 2-stroke engine, scavenging, volumetric efficiency, gasoline. I. INTRODUCTION The turbocharger is being driven by a gas turbine using the energy in exhaust gases. The main parts of turbocharger are turbine wheel, turbine housing, turbo shaft, compressor wheel, compressor housing & bearing housing. A 2-stroke S.I. Engine is an engine that uses gasoline as fuel. S.I.engine is a spark ignited engine that is the combustion is carried out by spark ignition, it is achieved by installation of spark plug on cylinder head. The strokes on which it works are: Suction, Compression, and Power/Working Stroke & Exhaust Stroke. The power produced by engine is only obtained in Power stroke. When a gas is compressed, its temperature increases. It is not rare for a turbocharger to be pushing out air that is 95 °C. Compressed air from a turbo may be cooled before it is served into the cylinders, using an intercooler or a charge air cooler. Figure 1. Layout of turbocharger with engine. A turbo rotations very fast maximum peak between 80,000 and 150,000 rpm depending on size, weight of the rotating parts, boost pressure established and compressor design. Figure 2.Turbocharger About Project Usually turbocharger is used for the purpose of increasing efficiency and power. It increases efficiency and reduces the exhaust emission, here we are making the 2-stroke turbocharged engine for more efficient by increasing efficiency, better scavenging and decreasing exhaust emissions.
