Design and analysis of variable compression ratio connecting rod

Abstract

Making the variable compression ratio a magnificent innovation which is already generating fine results. The remains of this discovery are what we will strive to develop. The compression ratio plays a vital role in bringing the exceptional control over the engine’s efficiency and performance. In the conventional I.C engines, the compression ratio remains fixed and its performance lays between the conflicting requirements. The most important aspect is that the drive units present in the vehicle should successfully operate at various speeds, loads and different conditions. In the SI engines, the variable compression ratio efforts the control over peak pressure of cylinder, improves the low load operation and cold start capability, which enables the multi fuel capability, increase of fuel economy, and emissions reduction. Hence, after the completion of this project, the VCR can be made as a key enabling technology of the future automobile industry.
