Abstract
Among IC engines, diesel vehicles are the major contributors to particulate mass emissions. Renewable fuels play a major role in reducing both gas phase and particulate mass emissions. In addition to renewable fuels, fuel additives are also investigated by scientists to compensate for the limitations of using renewable fuels. In this book chapter, a review of renewable fuels to be used in compression ignition (CI) engine was carried out. In addition to this, an experimental investigation was carried out in a single cylinder, water cooled variable compression ratio (VCR) diesel engine to make a comparative analysis among baseline diesel fuel and diesel + dodecanol (1% v/v) without renewable fuels. Dodecanol was chosen due to its advantages over other fuel additives. Results pertaining to in-cylinder pressure, hydrocarbon (HC) emission, carbon mono-oxide (CO) emission and particulate mass emission are presented. Soot was collected on a 47 mm quartz filter paper using a dilution tunnel and later analysed for soot morphology using scanning electron microscope (SEM). Energy dispersive spectroscope (EDS) analysis was also performed to find out the presence of metals in soot. Gravimetric analysis shows that Diesel + dodecanol (1% v/v) resulted in 2.62 mg of soot deposited on filter paper whereas diesel fuel showed 1.46 mg of soot deposited on filter paper for a duration of 30 min.
