Performance Evaluation of VCR CI Engine Using C-D Intake Manifold With Internal Grooving
Journal Title: International Journal of Mechanical and Production Engineering Research and Development (IJMPERD ) - Year 2018, Vol 8, Issue 1
Abstract
Compression ratio (CR) is a design parameter that influences efficiency, characteristics as well as emissions from the engine. Varying of Compression Ratio is done to increase fuel efficiency under varying loads. The experimental study is conducted on a four stroke VCR diesel engine of KIRLOSKAR make. The thermal performances are evaluated by operating the engine at different preset compression ratios (CRs) ranging from 12:1 to 20:1 and different injection pressures (IPS) of 150 bar, 200 bar And 250 bar and varying loads from 0 kg to 12 kg in steps of 3kg. The intake manifold of the VCR Engine is manufactured using mild steel in such a way that when air is passed through the manifold it gains velocity along with a swirl motion, due to the convergent and divergent manifold (C-D) with internal threading- Grooving. The swirl motion of the air helps in complete occupancy of the cylinder volume and when the fuel is injected, fuel mixes with the air uniformly due to which combustion of fuel will be maximum and the efficiency of the engine will increase. The C-D manifold is designed and tested for performance analysis in Solidworks and the results are evaluated.
