Emission Characteristics Of Two- Stroke Si Engine With Direct Fuel Injection (Dfi)
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 10
Abstract
Emission reduction and enhanced efficiency are the prime requirement for present day automotive engines. 2- Stroke IC Engines have definite advantages when compared to 4-Stroke IC Engine in terms of weight, power, and cost. 2 stroke IC Engine has the ability to produce greater power than 4 stroke IC Engines for the same displacement volume of the cylinder. Reduction in emissions along with SFC of such engines still makes them a viable alternative for their use in light motor cycles and micro light aircrafts. Extensive review of the available literature on the subject reveals that systematic methodology for choosing the right piston chamber geometry, location of inlet and exhaust port with respect to the transfer port, intake / exhaust port, opening and closing timings could be optimised for a given operating compression ratio and fuel composition to increase the efficiency of such engines. The present paper discussus the influence of direct fuel injection instead of supplying the air fuel mixture through a carburetor, on the performance of the 2 stroke cycle SI engine. A DFI system has been incorporated into the test engine by modifying its combustion chamber and bypassing the carburetor system. The performance of the engine and the emission characteristics have been studied at various operating conditions.
