Impact of Biodisiel Blended Fuel with Nano Particles on Deposition Formation of Compression Igition (CI) Engine - Nawabshah: QUEST, 2019. - 59p.
ABSTRACT
In this study engine performance, sound pressure level and endurance test have been carried out using biodiesel blend and diesel fuel (OF). The endurance test has been carried out for 60 hours of running. In this work, the single cylinder horizontal type diesel engine has been used without any modification. Total 3 fuel samples have been tasted , such as 830 (Jatrophabiodiesel 30%+Diesel 70%) B30A '2033 (30% of bidiesel+ 3% of Aluminum oxide+67% diesel) and diesel fuel (DI 00) as a base line. All parameters of the engine performance,and sound pressure level were calculated at constant RPM of 1 350 and variable loads 0.0 to 1 .6 at an interval of 0.1 Kg-m.
whereas the endurance test result has been carried out at constant load of 1 .0 Kg-m at constant RPM of 1350. The sound pressure level from the engine are also calculated from four different locations; front left back and top. From results it was found that, (BSFC) of biodiesel-blend and biodiesel-blend with additive was decreasing by increasing brake power on engine. The sound pressure level of all blended fuel were found to be reduced as com pared to diesel fuel (OF). ln endurance test, the visual inspect ion of valves surface was carried out for analysis of deposition of aromatic compounds on in let and Exhaust valves surface for all fuel samples (0100, 830, and 830Al203%). Detailed result of depositions has been taken by electron microscopic techniques. There are different aromatic compounds were found on inlet and Exhaust valves surface. The maxim um deposition of carbon was found
on diesel fuel, t he result shows that 74. l 0% in let valve and 72.1 5% Exhaust valves of carbon element has been analysis on valves surface. whereas in the biodiesel blend (830) has 59.32% i n let valve and 52.09% Exhaust valve. Biodiesel blend with additive (830A J 2 Q3) has 58.70% in let valve 47% Exhaust Valve respectively. The
kinematic viscosity of engine oil during endurance has been discussed in this work.
Engine wear and contamination of aromatic compounds reduces kinematic viscosity which reduces engine life. Finally, the lower (BSFC) of leads to reduces lower sound pressure level, and deposit ion of valves surfaces as compared to diesel fuel (OF).
