Abstract
This study focused on the performance and exhaust emissions of gasoline engines using gasoline-like fuel (GLF) produced from hard-resin of Yang (HY) by the fast pyrolysis process in semi-continuous reactors at pyrolysis temperature of 500 °C. Bio-oil products obtained from the process were distilled into heavy fuel at 200–350 °C and light fuel at 25–200 °C. HY (100%wt) generated 20.5%wt of light fuel and 30.8%wt of heavy fuel with 35.0%wt of gas and 13.7%wt of waste obtained. Light fuel as well as GLF and gasoline were tested for distillation, density, viscosity, heating value, flash point and silver strip corrosion under ASTM and also for the effect of GLF on performance and exhaust emissions of spark-ignition (SI) engines for a four-stroke single cylinder and fuel mixing system with carburetor. Positive results were shown for performance of brake torque, brake power and brake thermal efficiency. Findings revealed that brake specific fuel consumption was lower compared to gasoline. Carbon monoxide (CO) and hydrocarbon (HC) from engine exhaust were lower than gasoline with carbon dioxide (CO2) and nitrogen oxides (NOx) higher.
