An experimental assessment on the influence of high fuel injection pressure with ternary fuel (diesel-mahua methyl ester-pentanol) on performance, combustion, and emission characteristics of common rail direct injection diesel engine.

Optimization of fuel injection strategies can maximize the utilization of ternary fuel by addressing the issues concerning fuel consumption, engine performance, and exhaust gas emission. In the midst of the pervasiveness of plant-based biofuel, this paper focused on maximizing the mahua oil biodiesel usage in a diesel engine having a common rail direct injection (CRDI) system without any engine modifications.
