LAMINAR BURNING VELOCITY FOR BLENDS OF JOJOBA BIOGASOLINE WITH BASIC GASOLINE

Laminar burning velocity of natural gas/syngas-air mixture

This study suggests the equimolar mixture of Natural Gas (100% CH4) and Synthesis Gas (40% H2 + 40% CO + 20% CO2) as an alternative to reduce hydrocarbons consumption and reduce pollutant emissions. As a key parameter to characterize this combustible mixture, the laminar burning velocity was studied based on numerical simulations and experimental measurements in fl ames generated using a contou...

Effects of Flow Transients on the Burning Velocity of Laminar Hydrogen/air Premixed Flames

The effects of unsteady strain rate on the burning velocity of hydrogen/air premixed flames have been studied in an opposed nozzle configuration. The numerical method employs adaptive time integration of a system of differential–algebraic equations. Detailed hydrogen/air kinetic mechanism and transport properties are considered. The equivalence ratio is varied from lean to rich premixtures in o...

Strategies to Introduce n-Butanol in Gasoline Blends

The use of oxygenated fuels in spark ignition engines (SIEs) has gained increasing attention in the last few years, especially when coming from renewable sources, due to the shortage of fossil fuels and global warming concern. Currently, the main substitute of gasoline is ethanol, which helps to reduce CO and HC emissions but presents a series of drawbacks such as a low heating value and a high...

Influence of oxygen-enrichment air intake and bioethanol–gasoline blends on exhaust emissions and fuel consumption of gasoline engine

Among human activities, motor vehicles play the most important role in air pollution. Air pollution has negative impacts on people and on the environment. In this paper the effect of oxygen-enriched air (20.8%, 21.8%, 22.8%, 23.8% and 24.8%) and different bioethanol-gasoline blends (zero, 5%, 10%, 15%, 20% and 25%) in different engine speeds (1000 rpm, 2000 rpm and 3000 rpm) on the amount o...
