In this research, we evaluated the effect of diesetrol fuel blends (comprised of diesel, biodiesel, and ethanol) on diesel engine exhaust emissions. Biodiesel is a clean fuel of vegetable origin produced from the transesterification of waste cooking oil collected from restaurants. So as to ameliorate the properties of the biodiesel combustion such as cetane number, viscosity and cloud point, ethanol...
A liquefied petroleum gas (LPG) enriched port injection start aid was used to improve firing and emissions characteristics and overcome cold start difficulties for spark ignition (SI) methanol engines at low ambient temperature. The effects of injection timing of methanol and LPG addition fraction on cold start firing; and hydrocarbon (HC), formaldehyde, and unburned methanol emissions were investigated...
One of the major challenges in the production of biodiesel is the immiscibility of oil and methanol. The extent of dispersion between the two phases controls the mass and heat transfer rates and consequently the rate of the transesterification reaction. In this study, we report a novel design of a batch agitated vessel used for the production of biodiesel from palm oil. The new reactor is provided...
An experimental investigation was performed to study the effect of change of the IDF burner diameters on the flame characteristics (flame length, axial temperature distribution, and flame appearance) and flame emissions. The study was performed using a coaxial (CoA) circular inverse diffusion flame burners of different diameters. Burners' air diameters (da) were varied from 6 mm to 22.5 mm. The burner...
