Abstract

The need for alternative fuels has become increasingly critical due to the depletion of petroleum resources, growing automobile usage, and environmental concerns. Fish oil methyl ester, derived from fish oil, presents a promising alternative biodiesel, which can be produced from both edible and non-edible oils as well as animal fats. Diesel engines are valued for their efficiency, reliability, and durability, with performance and emissions being influenced significantly by factors such as fuel injection pressure and timing. This study examines how different fuel injection pressures and timings affect the performance and emissions of a Low Heat Rejection (LHR) engine running on blends of fish oil methyl ester, diethyl ether, and butanol. Results indicate that optimizing the injection pressure up to 230 bar enhances engine performance, fuel efficiency, and emission control. However, higher pressures show diminishing benefits, and fine-tuning the injection timing to 29° before top dead center further improves efficiency and reduces emissions. This research highlights the crucial role of optimizing injection parameters to maximize engine performance and reduce emissions when using alternative fuels.

Keywords: FOME, DEE, butanol, injection pressure, injection timing
