Combustion of gasoline with oxygen-containing and nano-additives: An experimental study, modeling, optimization, and analysis survey
Background
Pollutants emitted from fuel combustion have become a global concern, prompting researchers to explore solutions like fuel formulation modification.
Methods
This study delved into enhancing gasoline fuel performance and octane number by incorporating varying proportions of 2-methyl-1-propanol, bioethanol, MTBE additives, tert‑butanol, and nanoparticles (ZnO, ZrO2, and CNT). These compositions underwent assessment at different engine loads and speeds. Vapor pressure, a fundamental property of gasoline that signifies its volatility, was examined. Despite the utilization of diverse additives and enhancers, their impact on vapor pressure was minimal at relatively low concentrations.
Significant findings
As a result, flash point, octane number, and engine performance were evaluated for the developed fuels. The findings unveiled improved engine performance coupled with reduced emissions. The octane number demonstrated enhancement, approaching gasoline's, while the combustion point remained similar. Notably, pollutant levels exhibited significant reduction.
When comparing gasoline fuel at an engine speed of 1500 RPM and a throttle opening of 30 % with gasoline mixed with 2-methyl-1-propanol alcohol, MTBE, and zirconium dioxide under identical conditions, the results showed a reduction of 82.8 % in carbon monoxide emissions, carbon dioxide decreased by 54.05 %, unburnt hydrocarbons decreased approximately by 42.42 %, nitrogen oxides reduced by 22.97 %, engine power increased by 0.5 %, torque increased up to 164 %, and the octane number increased by 7.03 %.
