“…Unburned hydrocarbons were lessened when neat RapO was used. McDonnell et al [12] used semirefined RapO blends up to 75% in an agricultural tractor direct injection diesel engine (DDE) and resulted that oil blends up to 25% were suitable alternative fuels. More specifically, as oil content in the fuel was increased, Power was reduced and BSFC was augmented, but according to the tractor operators, engine performance was not affected highly; while engine lubricating oil was slightly influenced from the fuel alteration and injector fouling was increased, but not quantified.…”

“…Then, four (4) types of fuels for each VO were experimented; three VO/DF blends (20/80, 40/60, and 70/30 volumetrically) and 100% pure VO. The selection of blends was based on previous studies [11,12,17,22,23] and aimed on an overall blend range. DF was used in ambient temperature and only blends and pure VOs were first preheated.…”

A comparative experimental investigation was conducted to evaluate the performance and exhaust emissions of an agricultural tractor engine when fueled with sunflower oil, rapeseed oil, and cottonseed oil and their blends with diesel fuel (20/80, 40/60 and 70/30 volumetrically). Tests were also carried out with diesel fuel to be used as a reference point. Engine power, torque, BSFC, thermal efficiency, NO x and CO 2 were recorded for each tested fuel. All vegetable oils resulted in normal operation without problems during the short-term experiments. The 20/80 blends showed unstable results, in comparison to higher oil content fuels. Power, Torque and BSFC were higher as oil content was increased in the fuel. Rapeseed oil fuels showed increased power, torque and thermal efficiency with simultaneous lower BSFC in comparison to the other two vegetable oils. Cottonseed oil fuels gave better engine performance than sunflower oil fuels. In all oil types, NO x emissions were augmented when fuel oil percentage was increased. Cottonseed oil fuels led to higher NO x emission increase compared to rapeseed oil fuels. CO 2 emissions showed a tendency to be increased as the oil content was evolved. The highest CO 2 emissions were given by cottonseed oil fuels, followed by rapeseed and sunflower oil.

“…Canola and mustard oils also have high energy content per unit weight and are two of the most efficient sources of bioenergy in terms of British thermal units (BTUs) per acre planted. These attributes have led to interest in the adoption of canola and mustard oils as sources of biodiesel fuel (McDonnell et al 2000).…”

“…Research works performed during the last decades with an aim to extend biofuel production and enlarge the variety of renewable fuels indicate that rapeseed oil (RO) could also be used for tractor fuelling (Bialkowski et al 2004;McDonnell et al 2000;Labeckas and Slavinskas 2006a;Nwafor et al 2000). Potential advantages and disadvantages as well as the main properties related to the use of RO and its various blends with ethanol, petrol and…”

The article deals with the testing results of a four stroke four cylinder, DI diesel engine operating on pure rapeseed oil (RO) and its 2.5vol%, 5vol% and 7.5vol% blends with ethanol (ERO) and petrol (PRO). The purpose of this study is to examine the effect of ethanol and petrol addition to RO on blend viscosity, percentage changes in brake mean effective pressure (bmep), brake specific fuel consumption (bsfc), the brake thermal efficiency (çe) of a diesel engine and its emission composition, including NO, NO2, NOX, CO, CO2, HC and the smoke opacity of exhausts. The addition of 2.5, 5 and 7.5vol% of ethanol and the same percentage of petrol into RO, at a temperature of 20 °C, diminish the viscosity of the blends by 9.2%, 21.3%, 28.3% and 14.1%, 24.8%, 31.7% respectively. Heating biofuels up to a temperature of 60 °C, diminishes the kinematic viscosity of RO, blends ERO2.5–7.5 and PRO2.5–7.5 4.2, 3.9–3.8 and 3.9–3.7 times accordingly. At a speed of 1400–1800 min‐1, bmep higher by 1.3% if compared with that of RO (0.772–0.770 MPa) ensures blend PRO2.5, whereas at a rated speed of 2200 min‐1 , bmep higher by 5.6–2.7% can be obtained when fuelling the loaded engine, ë = 1.6, with both PRO2.5–5 blends. The bsfc of the engine operating on blend PRO2.5 at maximum torque and rated power is respectively 3.0% and 5.5% lower. The highest brake thermal efficiency at maximum torque (0.400) and rated power (0.415) compared to that of RO (0.394) also suggests blend PRO2.5. The largest increase in NOXemissions making 1907 ppm (24.8%) and 1811 ppm (19.6%) compared to that of RO was measured from a more calorific blend PRO7.5 (9.99% oxygen) at low (1400 min‐1) and rated (2200 min‐1) speeds. The emission of carbon monoxide from blends ERO2.5–5 throughout the whole speed range runs lower from 6.1% to 32.9% and the smoke opacity of the fully loaded engine changes from 5.1% which is a higher to 46.4% which is a lower level if compared to the corresponding data obtained using pure RO. The CO2 emissions of carbon monoxide and the temperature of the exhausts generated by the engine running at a speed of 2200 min‐1 diminish from 7.8 vol% to 6.3vol% and from 500 °C to 465 °C due to the addition of 7.5vol% of ethanol to RO.
