“…Unfortunately, there is conflict and inconsistency in the literature regarding control of nitrogen oxides (NO x ) with biodiesel relative to diesel fuel (Dorado et al 2003;Agarwal et al 2006;Szybist et al 2007;Agarwal and Rajamanoharan 2009). However, particulate matter (PM), an important class of regulated emissions gets abated by this renewable fuel (He et al 2009). …”

“…It has the potential to reduce most of the gaseous regulated pollutants such as total hydrocarbons (THC) and carbon monoxide (CO) emissions on account of more complete combustion (Lapuerta et al 2002;Turrio-Baldassarri et al 2004;He et al 2009). Unfortunately, there is conflict and inconsistency in the literature regarding control of nitrogen oxides (NO x ) with biodiesel relative to diesel fuel (Dorado et al 2003;Agarwal et al 2006;Szybist et al 2007;Agarwal and Rajamanoharan 2009).…”

In present study a turbocharged, medium duty compression ignition engine was alternatively fuelled with biodiesel to investigate the changes in particulate matter composition, relative to that taken with diesel fuel. The engine was operated on an AC electrical dynamometer in accordance with an 8-mode, steady-state cycle. The numbers of particles were estimated through electrical low pressure impactor, while sulfates and trace metals were analyzed by ion chromatography and inductively coupled plasma-atomic emission spectroscopy, respectively. Nitric oxides and nitrogen dioxides were measured separately using SEMTECH-DS. Experimental results revealed that, on account of elevated ratios of nitrogen dioxide to nitrogen oxides, mean accumulation mode particles were 42 % lower with biodiesel. On the other hand, nuclei mode particles were higher with biodiesel, owing to heterogeneous nucleation and accounting for an increase in sulfate emissions up to 8 % with biodiesel as compared to diesel. On the average, trace metal emissions were significantly reduced showing 65-85.4 % reduction rates with biodiesel, relative to its counterpart. Further to this, individual congeners such as iron, calcium, and sodium were the predominant elements of the trace metals emitted from engine. The mean relative decrease in iron and calcium was 89-97.8 and 77.6-87 %, respectively, while the relative rise in sodium was in the range of 29-46 % with biodiesel. Further, elements such as zinc, chromium, and aluminum showed substantial abatement, whereas potassium, magnesium, and manganese exhibited irregular trends on account of variable engine loads and speeds during the various modes of cycle.

“…The application of biodiesels in diesel engines is a relatively mature technology in terms of production and combustion in diesel engines. In general, biodiesels can burn well in diesel engines and produce lower CO, hydrocarbon and particular matter (PM) emissions compared to petroleum diesel (PD) [4][5][6][7][8][9][10]. However, has the use of biodiesel delivered its main objective, that of-carbon reduction, and by how much compared to PD?…”

To maximize CO2 reduction, refined straight used cooking oils were used as a fuel in Heavy Goods Vehicles (HGVs) in this research. The fuel is called C2G Ultra Biofuel (C2G: Convert to Green Ltd) and is a fully renewable fuel made as a diesel replacement from processed used cooking oil, used directly in diesel engines specifically modified for this purpose. This is part of a large demonstration project involving ten 44-tonne trucks using C2G Ultra Biofuel as a fuel to partially replace standard diesel fuels. A dual fuel tank containing both diesel and C2G Ultra Biofuel and an on-board fuel blending system-Bioltec system was installed on each vehicle, which is able to heat the C2G Ultra Biofuel and automatically determine the required blending ratio of diesel and C2G Ultra Biofuel according to fuel temperature and engine load. The engine was started with diesel and then switched to C2G Ultra Biofuel under appropriate conditions. Exhaust emissions were measured using PEMS (Portable Emission Measurement Systems) on one of the trucks under real world driving conditions. Comparisons of emissions between neat diesel mode and blended fuel mode were made. The results show that C2G Ultra Biofuel can reduce particulate matter (PM) and CO emissions significantly compared to the use of pure diesel.
