The experimentation was carried out on a setup consists of single cylinder port injection dual fuel, four stroke Common rail direct injection (CRDI), Variable Compression Ratio (VCR) and open Electronic Control Unit (ECU) engine connected to eddy current dynamometer. The diesel fuel is injected directly into the combustion chamber as a pilot fuel with common rail fuel injection system and methanol fuel is injected into the intake manifold by using separate fuel injector as main fuel. The aim of this project is to perform the experimentation for Methanol (CH3OH) utilization in Dual fuel compression ignition and investigation of the Combustion characteristics and performance analysis and emission analysis of the engine running at constant 1500 rpm and 100% load. Five methanol replacement ratios (MRR) such as 0% (pure diesel), 15 %, 25%, 35%, and 45% were conducted. From study it is observed that, premixed diesel combustion was retarded as well as improved, diffusion diesel combustion was increased and progressed, ignition delay was longer, combustion duration was lowered, methanol is the most beneficial in terms of extending ignition delay and lowering combustion duration for the specific methanol replacement ratio.Net heat release rate (HRR) and NOx increases consistently for increasing MRR at 100% load. The BTE decreases consistently with increasing the MRR. Lower CO and smoke opacity emission was reported with high MRR. HC and CO2emissions were higher for high MRR.
