A Simulation of the Impact of Biodiesel Blends on Performance Parameters in Compression Ignition Engine

Abstract

Recently, there has been significant interest in biodiesel since it depends on renewable resources, which is essential given the increasing depletion of fossil fuels. Using palm oil in biodiesel production is an innovative application of botanical resources in this sector. Simulation research examined how blending palm oil with Iraqi conventional diesel influences engine performance. The impact of several mixtures, consisting of different proportions (5%, 10%, 15%, and 20%) of palm oil and diesel, on engine fuel consumption, volumetric efficiency, torque, brake mean pressure, brake power, and thermal efficiency was evaluated in each case. The study found that using palm oil fuel at a mixing ratio of 20% resulted in a 4% increase in fuel consumption. Furthermore, a 3% enhancement in volumetric efficiency was also noted. Again, there was a noticeable reduction in the torque, power, and average adequate pressure levels across all diesel fuel mixing ratios compared to diesel fuel, which exhibits the highest value.
