“…The results were similar to those found by DELALIBERA et al (2010) for sunflower oil with and without preheating (90 °C). For the consumption results under load regime, corroborate with those presented by MARTINI et al (2012), which observed a tendency on increase of the consumption with the increase of temperature on preheating of soybean oil in engine under regime of absorption at 70% of the nominal power.…”

“…In spite of being favorable from the energetic and environmental point of view, the direct use of vegetable oils in diesel engines is problematic. Studies with several oils have shown that the application of these as fuel causes carbonization excess of the combustion chamber; contaminates and degrades the lubricant and causes accelerated wear of moving parts (HAZAR & AYDIN, 2010;DELALIBERA et al, 2012).…”

ABSTRACT:With the rise of restrictions imposed by law for gases emission, several technologies both for petrodiesel (PD) or diesel engines are been applied, such as the sulfur reduction and the injection electronic command, followed of gases recirculation and/or after-treatment. The utilization of biofuels is considered as an interesting option for pollutants reduction. In this study was evaluated the performance on short duration tests (minor period than the factory indication of the lubricant lifespan) of the Diesel engine fueled with four vegetable oils. With the aim to select the most interesting oils for future evaluations in long duration tests. The analyzed variables were fuel consumption, power relative loss and opacity, for oils of linseed, crambe, rapseed, jatropha , with 100 °C preheating and engine work temperature (60 °C) comparing those with the PD. It was verified that the vegetable oils, on average, present a lower consumption than the PD for the cases of working without load, however with load, they presented higher consumption. In addiction were observed that the oils show a higher relative power loss in relation of PD and provides lower emission of particulate matter. Crambe and canola presented the best performance among the evaluated oils.

“…According to MELILLO et al (2009) there is a global incentive for the partial substitution of diesel fuel of mineral origin by others from plant and animal origin, commonly called biodiesel. Added to this, the growing concern over environmental pollution and the increase in oil prices has driven the development of research in seeking for renewable fuels (DELALIBERA, 2012).…”

ABSTRACT:The use of fuels for agricultural Diesel engines cycle, both of mineral origin (Diesel) or vegetable and animal origin (biodiesel) can significantly alter its performance. Therefore, the aim of this study was to quantify the change in torque, power and consumption of agricultural Diesel engine fuel using minerals and vegetables fuels. It was used a tractor power take-off coupled to a magnetic brake dynamometer (for measuring speed and torque for subsequent calculation of power), and a flow meter (for measuring the hourly fuel consumption and specific fuel consumption calculation). Eleven different fuels (S10 mineral diesel with 5%, 10%, 15%, 20% and 50% biodiesel and mineral diesel S500 with 5%, 10%, 15%, 20% and 50% biodiesel, have been used pure biodiesel B100). The results indicate that the increase of biodiesel in mineral diesel reduces torque and power, increases the specific fuel consumption and practically does not change the hourly consumption. This reduction in torque and power occurs with greater intensity in Diesel S10. Additions of 10% biodiesel in mineral diesel reduces the maximum torque 1.65 Nm (0.6%), the maximum power at 0.33 kW (0.6%) and increases the specific fuel consumption of 3.6 g kWh -1(1.3%).

“… Problems related to high concentration of biodiesel: o Diesel fuel with high concentration of biodiesel can reduce engine life. Delalibera, Campolina, Neto, and Ralisch (2012) when analyzing the performance of diesel engine fuel with a preheated blend of high concentration of biodiesel had identified that engine fuel injectors had reduced life, common rail system was unstable in delivering fuel, and there an increase of particulate mater (PM). o The type of engine oil sold in Latin America could impact engine durability.…”

The Latin American region has many important ongoing infrastructure projects. It is a global source of mining materials such as copper and iron. Thus, the region is an important market for construction equipment manufacturers such as Caterpillar, John Deere, Komatsu, Volvo, and CNH. However, it is not financially feasible for these manufactures to test construction machines in all 33 countries. Consequently, there is a significant lack of engine system understanding in this region due to its diverse operating conditions. This research provides a system engineering analysis of how diesel engine durability is affected by the environmental factors such as altitude and fuel quality in Latin America. Examination of engine oil analyses shows that oil condition provides a leading indicator of premature internal engine wear in Latin America. The study further relates environment factors in Latin America such as altitude to machine diagnostic trouble codes.
