Effect of Some Turkish Vegetable Oil-Diesel Fuel Blends on Exhaust Emissions

Ignition Delay and Soot Emission Characteristics of Methanol-Diesel Fuel Blends

“…1973 Fuel injected after ignition bums then in locally fuel rich atmosphere resulting in an increase of soot formation (Someya, 1993;Kaminato and Kobayashi, 1991). The result of this mechanism is seen from the relation between compression ratio and soot emission (Ergeneman et al 1997 Some characteristics of the basic diesel fuel and methanol are given in Table 3.…”

Physiochemical and Phase Behaviour Study of Jatropha curcus Oil - Ethanol Microemulsion Fuels Using Sorbitane Fatty Esters

“…Additionally, the vegetable oils have higher cloud and pour points considered as unfavorable parameters in cold weather conditions [11]. So several methodologies have been applied to overcome these difficulties for preparing biofuel such as dilution method where vegetable oils in small portions are blended with diesel; microemulsion (ME) method where oils are mixed with alcohols using surfactants; pyrolysis by simple cracking of vegetable oils either by heating directly or with catalysts, a less energy efficient method and lastly transesterification comprising a reversible chemical reaction between oil and short chain alcohols producing biodiesel and glycerol with catalysts [12][13][14][15]. The biofuel obtained through these methods are biodegradable and environmentally friendly however their high cost, poor cold flow properties and increasing nitrogen oxides (NO x ) in exhaust emissions have been few of the disadvantages [16][17][18].…”
