Experimental Investigation on Use of Coconut Oil as Lubricant in Two Stroke SI Engine

Lubrication circuit is one of the most important ones in the engine, as engines cannot run smoothly for more than few minutes without lubricating oil ,the serious drawback of now day petroleum based lubricating oil is emission. This problem may be overcome by the using vegetable oils such as coconut oil as it shares most of the salutary properties of other vegetable oils like lubricity, high flashpoint of 225⁰ C which is more than 2T oil. This paper focuses on evaluation of performance of coconut oil as a alternative lubricating oil and its effect on the engine performance, experiments are conducted with standard injection parameters, at constant speed , and at different loads ,various parameters like Brake power, specific fuel consumption, total fuel consumption, Thermal efficiency & emission were studied, with the results so obtained the performance curves were drawn and compared to ascertain the suitability of using coconut oil as lubricant in two stroke SI engine, and experimental results show that there is less emission and reduced Total fuel consumption

The Properties of an Aluminium Metal Matrix Composites: A Review

Now a days aluminium matrix composites setting a trend in its usage in various sectors especially in the areas of space, automobile, marine applications due to its less density as well as improved mechanical and tribological properties. The usage of aluminium is restricted due to its limited strength and hardness. In order to improve those properties aluminium is added with other elements, one such popular example is the aluminium metal matrix composites. There is a significant improvement in strength, hardness, wear resistance, creep and fatigue properties of aluminium matrix with the addition of various reinforcements. An attempt has been made to summarize the effect of various reinforcements on aluminium matrix on mechanical and tribological properties which are processed under various casting techniques. This paper presents the overview of the effect of addition on different reinforcements in aluminium alloy highlighting their merits and demerits

Influence of Water Absorption, Impact and Damping on CURAUA/Glass Fibers Polyester Composites

Curaua fiber is one of the strongest natural fibers rich in cellulosic content and is being currently considered as reinforcement for any polymer based matrix composites. The current work investigates the dynamic and mechanical properties of polymer matrix composites reinforced with continuous curaua fiber and E glass fiber. The fabricated polymer matrix composites by hand layup technique will be tested for water absorption, Izod, Charpy, damping test and SEM analysis

Not AvailableHost plant resistance is an effective means of managing aphid pests in safflower but its genetic basis is not known. In this study, F1 and F6- recombinant inbred lines (RILs) produced from the CO-1 × EC-523368-2 cross were phenotyped for tolerance to the aphid, Uroleucon compositae based on days-to-wilt (DW) after infestation. The F1 plants showed dominance effect and RILs exhibited quantitative variation. The RIL population was genotyped with 242 simple sequence repeat (SSR) markers, which included a set of 150 new SSRs designed through next generation sequencing and bioinformatics approaches. Two quantitative trait loci (QTLs), QUc-Ct3.1 and QUc-Ct5.1, putatively associated with DW after aphid infestation were detected. QUc-Ct3.1 was a major QTL located on linkage group (LG) 3 with the closest marker SafM-290 (LOD = 18.3), which explained 31.5% of the phenotypic variation. QUc-Ct5.1 was a minor QTL located on LG-5 with the closest marker CtDES-237 (LOD = 7.0), which explained 9.1% of the phenotypic variation. This is the first report and a significant lead towards discovering genes for tolerance to aphids in safflower.SERB, Government of India through National Post Doctoral Fellowship (PDF/2016/003679
