Summary

American Saffron Oil methyl ester (ASOME) shows promise as a sustainable biodiesel feedstock. Blends like B20 improved diesel engine performance and reduced harmful emissions, validated by simulation and experimental data.

Area Of Science

Renewable Energy Sources
Combustion Engineering
Chemical Engineering

Background

Diesel engines are crucial in transportation, agriculture, and manufacturing.
Rising fuel costs and environmental concerns necessitate alternative fuels.
Biodiesel offers a potential replacement for conventional diesel fuel.

Purpose Of The Study

To evaluate American Saffron Oil as a viable feedstock for biodiesel production.
To analyze the properties and performance of biodiesel derived from American Saffron Oil.
To assess the impact of American Saffron Oil Methyl Ester (ASOME) blends on diesel engine performance and emissions.

Main Methods

American Saffron Oil was extracted using the transesterification method to produce ASOME.
ASOME's physical and chemical properties were tested against ASTM standards.
Various fuel blends (B20, B40, B60) of ASOME and diesel were created and tested.
Diesel engine tests were conducted using DIESEL-RK simulation software and experimental validation.

Main Results

The B20 blend (20% ASOME) demonstrated superior performance and lower emissions.
DIESEL-RK simulations indicated improved engine performance and reduced pollutants for ASOME blends.
Experimental data confirmed a 5.7% increase in brake thermal efficiency.
Hydrocarbon and carbon monoxide emissions decreased by 2.5% and 14.3%, respectively.

Conclusions

American Saffron Oil is a feasible feedstock for biodiesel production.
ASOME-based biodiesel blends, particularly B20, offer significant environmental and performance benefits.
The study validates the use of ASOME as a sustainable alternative fuel for diesel engines.
