“…Kinematic viscosity is the ratio of the fluid dynamic viscosity to its density and has a significant impact on fuel delivery and power output. It determines the rate of flow of the fuel, and too high a value can lead to pumping issues and atomization in the injection system [14].…”

Compression ignition engines have wide application in the transportation, agricultural, construction and industrial sectors which are critical for the economic sustainability of any nation. These engines are powered with petroleum diesel which is however, been threatened by the reality of crude oil going into extinction in some couple of years if new reserves are not discovered, and also the need to reduce global warming; a consequence of the effect of its combustion products. Biodiesel is a renewable fuel with similar properties to petroleum diesel, and can be used purely or in blends without the need for modifying the existing engines. The thermal efficiency of an engine is a very important performance indicator, and researchers would stop at nothing to ensure its improvement. The kinematic viscosity is one of the fuel's properties which contribute to an engine thermal efficiency. This work is thus designed to review some past studies on the use of biodiesels and its blends in engines and find a correlation between the kinematic viscosity and the thermal efficiency. A correlation was established to exist between the fuel kinematic viscosity and the engine thermal efficiency.

W artykule przedstawiono wyniki badań zadymienia spalin silnika o zapłonie samoczynnym AD3.152 zasilanego olejem rzepakowym (OR)oraz jego mieszaninami z eterem dietylowym (DEE). Wszystkie niezbędne badania wykonano w warunkach ustalonych dla wybranych prędkości obrotowych wału korbowego tj. 1000, 1500 i 2000 obr/min oraz obciążeń 40, 80 i 120 Nm. Uzyskane wyniki potwierdzają, że dodatek eteru dietylowego w objętości 40% do oleju rzepakowego zmniejsza zadymienie spalin nawet o ok. 50% w stosunku do silnika zasilanego olejem rzepakowym.

“…Carbon buildup (coking) and injector clogging continues over time, resulting in high maintenance costs and/or shorter life of Compression Ignition (CI) engines. Success has been reported for blends of vegetable oil and diesel in diesel engine with vegetable oil percentage composition up to 20%, however, the high viscosity and low volatility of the vegetable oil becomes a major drawback for their utilization at higher percentage composition in the blends [11].…”

Degummed Pongamia oil – Ethanol microemulsions as novel alternative CI engine fuels for remote Small Island Developing States: Preparation, characterization, engine performance and emissions characteristics

Diminishing fossil fuel reserves, rising market price for diesel and the need to combat greenhouse gas emissions have led to the development of a crucial area of research into alternative fuels for diesel engines. In this work, a hybrid fuel was prepared for the first time by blending Pongamia oil, hydrated ethanol (95% purity) and butanol (as a surfactant). To eliminate engine modification and reduce injector clogging in the diesel engine, degummed Pongamia oil was utilized for preparing hybrid fuels. The results show that the density and viscosity of Pongamia oil reduced considerably after blending with ethanol and was brought closer to that of diesel. The gross calorific values were comparable with that of diesel. The brake thermal efficiencies of using hybrid fuels on a compression ignition engine were very similar to that of diesel. The emissions characteristics of hybrid fuels show reduced emissions of CO 2 , NO x and SO 2. The hybrid fuel blends E 22 B 27 DPO 51 and E 17 B 16 DPO 67 prepared with degummed Pongamia oil show the lowest emissions. Thus, these hybrid fuels have the potential to substitute diesel to run diesel powered inter-island shipping vessels, fishing boats and smaller power plants for household electricity in remote and outer islands of developing countries.
