The standard configuration parameters of a Variable compression ratio (VCR) engine neglect to give specific execution with biodiesel from distinctive origins. Alongside, a bunch of exploration of diversified biodiesel over performance and emission analysis, extremely constrained work has been taken out on combustion analysis with VCR. This survey was performed to identify the impact of compression ratio on the combustion characteristics of a diesel engine fueled with Calophyllum inophyllum oil methyl ester (COME) and its blends with diesel. Experiments were conducted at a fixed speed of 1500 RPM, full load and at different compression ratios of 16:1, 17:1 and 18:1. Results, revealed that combustion duration of Calophyllum inophyllum oil was more, while the ignition delay period was shorter than that of diesel.
