“…In the presented studies, NOx concentration increased at higher engine loads, regardless of the type of fuel and biocomponents, which is consistent with the conclusions of the authors of the study [14]. These results confirm the conclusion in the review [12] that the emissions were significantly involved with the engine load. As in [13,17], it was found that HVO addition preferably reduces NOx concentration in exhaust gases.…”

The authors have examined the influence of biocomponents of different origin on exhaust gases emitted from a light duty vehicle with a compression ignition engine. The car was fuelled with diesel fuel containing 20% V/V fatty acid methyl esters and diesel fuel with 13% V/V hydrotreated vegetable oils and 7% V/V fatty acid methyl esters. Commercial diesel fuel containing 7% V/V esters was a reference. The tests were performed on the chassis dynamometer in static engine operating conditions. It was stated that the addition of mentioned biocomponents into diesel fuel slightly changed the concentration of regulated components in exhaust gases with/without after-treatment devices. The presence of bio-components has reduced nitrogen oxide concentration in the treated exhaust gases as compared to the commercial diesel. We observed no trends of changes in unburned hydrocarbon concentrations depending on the type of tested fuels and presence of the diesel particle filter. Unburned hydrocarbons consisted mainly of fractions containing up to five carbon atoms per molecule. Whatever the type of fuel examined, carbonyl compounds such as formaldehyde and acetaldehyde were found only in the untreated exhaust gases.

“…From this figure, at 25% load the FMEP varies from 16.1% to 18.5% of IMEP and at 100% load, it varies from 0.4% to 2.2% of IMEP. The cetane number increase associated with biodiesel contributes to the earlier start of combustion when compared to diesel, which might lead to higher cylinder peak pressure and output power (see Figure 3) [26]. However, the cetane number of essential oil blends is quite low (Table 2) as compared to neat diesel and WCB.…”

Essential oils are derived from not-fatty parts of plants and are mostly used in aromatherapy, as well as cosmetics and perfume production. The essential oils market is growing rapidly due to their claimed health benefits. However, because only therapeutic grade oil is required in the medicinal sector, there is a substantial low-value waste stream of essential oils that can be used in the transportation and agricultural sectors. This study investigated the influence of orange, eucalyptus, and tea tree oil on engine performance and combustion characteristics of a multi-cylinder compression ignition engine. Orange, eucalyptus, and tea tree oil were blended with diesel at 10% by volume. For benchmarking, neat diesel and 10% waste cooking biodiesel-diesel blend were also tested. The selected fuels were used to conduct engine test runs with a constant engine speed (1500 RPM (revolutions per minute)) at four loads. As the load increased, frictional power losses decreased for all of the fuel samples and thus mechanical efficiency increased. At higher loads (75% and 100%), only orange oil-diesel blends produced comparable power to diesel and waste cooking biodiesel-diesel blends. Fuel consumption (brake and indicated) for the essential oil-diesel blends was higher when compared to base diesel and waste cooking biodiesel-diesel blends. Thermal efficiency for the essential oil-diesel blends was comparable to base diesel and waste cooking biodiesel-diesel blends. At higher loads, blow-by was lower for essential oil blends as compared to base diesel and waste cooking biodiesel-diesel blends. At 50% and 100% load, peak pressure was lower for all of the essential oil-diesel blends when compared to base diesel and waste cooking biodiesel-diesel blends. From the heat release rate curve, the essential oil-diesel blends ignition delay times were longer because the oils have lower cetane values. Overall, the low-value streams of these essential oils were found to be suitable for use in diesel engines at 10% blends by agricultural producers of these oils.

“…PM emisyonu, homojen bir yakıt-hava karışımı oluşmaması sonucu özelikle yanma odasının yakıtça zengin bölgelerinde oluşmaktadır. Literatürde belirtildiği gibi BD yakıtların setan sayılarının yüksek oluşu ve yapılarında oksijen bulunması daha verimli bir yanma sağlayarak PM emisyonunu azaltmaktadır [28,33,39,41,43]. Şekil 14(b)'de, NO x emisyonu değerleri devir sayısıyla önemli ölçüde artmakta olup BD yakıt ve karışımları D yakıtına göre yüksek değerlere sahiptir.…”
