“…As previously stated, this biofuel has free oxygen in its molecule, which reduces the formation of fuel-rich zones inside the combustion chamber; hence enhancing performance and efficiency during diffusion combustion, and reducing particulate matter emissions (Sahoo et al, 2009;Chauhan et al, 2012). Particulate emissions from biodiesel combustion in diesel engines are lower than those of diesel fuel (Janaun and Ellis, 2010;Ong et al, 2011;Xue et al, 2011;Bora and Baruah, 2012). To visualize smoke density from both types of diesel and blends with babassu biodiesel at varying proportions, the data fit a linear regression model were plotted in Figure 2.…”

Biodiesel is an alternative fuel to diesel engines. This study aimed to evaluate fuel consumption and smoke density of agricultural tractors fueled by biodiesel, diesel, and biodiesel/diesel mixtures in a tilled field. Treatments consisted of distilled methyl ester (biodiesel) of babassu (Orbinya martiana) and seven combinations of it with two standard diesel fuels (B S1800 and B S50). The blending ratios were 0, 5, 15, 25, 50, and 100% biodiesel in diesel oil (B0, B5, B15, B25, B50, and B100, respectively). Regarding the results for hourly volumetric consumption, no difference was found between B0 and B100 when using B S1800, whereas an 8% increase was observed when using the S50. The weighted hourly consumption increased by 11.29 and 16.9% from B0 to B100 using B S1800 and B S50, respectively. Similarly, the specific fuel consumption increased by 11.1% and 14.3% from B0 to B100 using B S1800 and B S50, respectively. Yet, when comparing B0 and B S1800, the smoke density reduction was 68.6% and between B S50 and B100 was 58.0%. Our findings show that babassu biodiesel is a suitable substitute for diesel oil, without causing any damage to the tractor's engine.

“…It can be stated that running biodiesel in diesel engines instead promotes significant reduction in particulate emissions (Ong et al, 2011;Xue et al, 2011;Bora and Baruah, 2012). Moreover, Table 4 shows that opacity levels would be within the limit of 2.5 m −1 defined by the CONAMA resolution number 251/1999251/ (CONAMA, 1999.…”

Renewable energy benefits and disadvantages have been subject of major discussions and studies. Thus, this study aimed at assessing the smoke opacity from a farming tractor running two types of diesel, B S1800 (B0) and B S10 (B0), and ethyl biodiesel from babassu oil at two rates (B50 and B100), at six day periods (2, 6, 10 am, 2, 6 and 10 pm). The study was conducted at the Department of Agricultural Engineering of the Faculty of Agricultural and Veterinary Sciences, UNESP, in Jaboticabal -SP, Brazil. The results showed a reduced smoke opacity during daytimes of lower ambient temperature and higher air relative humidity. In addition, smoke opacity was reduced as higher rates of babassu biodiesel were added to B S1800 diesel and B S10; thus, consisting of an efficient procedure of reducing smoke opacity in farming tractor engines.

“…Moreover, the presence of free oxygen in biodiesel molecule (reduced fuel-rich zones inside combustion chamber and increased yield during diffusive combustion), increasing combustion efficiency and reducing considerably the production of particulate matter (Sahoo et al, 2009;Chauhan et al, 2012). Biodiesel burning in diesel engines significantly reduces the emissions of particulate matter compared to diesel (Bora and Baruah, 2012).…”

Given the need for new alternatives to finite source of energy from fossil fuels, testing of alternative fuels has become quite important. Studies have been carried out using sets of tractor with equipment to evaluate the operational performance together with supplying diesel and biodiesel. Biodiesel is a feasible alternative as it waives adjustments in diesel cycle engines, unlike other clean fuels such as natural gas or biogas, for example. This study aimed at to assess the operational performance and smoke density of a tractor running on diesel and biodiesel, through the parameters of fuel type and engine speed. The assessed engine speeds were 1800, 1900, 2000, 2100, 2200, 2400 and 2600 rpm and the fuel types were diesel B S1800, diesel B S500, soyabean biodiesel and murumuru biodiesel. The results showed that there was an increase in the specific consumption for all fuel types with increasing engine speed, and 1900 and 2000 rpm, mainly for the use of biodiesel speed range that least interferes with the performance. The smoke density was reduced when using soyabean and murumuru biodiesels.
