An experimental investigation on the performance emission and combustion characteristics of diesel engine using Caulerpa Racemosa biodiesel as an alternate fuel

Abstract

newline The consumption of petroleum products is steadily increasing as the number of automobiles on the road continues to rise. As a result, hydrocarbon consumption raises pollution levels in the environment. There is a compelling need to resolve the issues, which include unreliable fuel delivery and pollution of the environment. The depletion of resources produces rise in diesel demand, and uncertainty of its availability is viewed as a critical factor, prompting research into alternate energy sources (can be supplemented or replaced for fossil fuels). Caulerpa Racemosa biodiesel-based proposed blend in a diesel engine with a single-cylinder. During testing, a single-cylinder diesel motor requires no equipment adjustments. The effects of density proportions with compressions for various blends starting from B5 to B10, B20 to B40, B60 to B80, and finally, B100 mixes have been demonstrated. For various fuel infusion weights, i.e., 180, 200 and 220 bar, fuel blends were used to conduct tests for the engine. When compared to faultless diesel and 100 percent biodiesel mix, the decrease in smoke darkness was as much as 10 to 15% via the stack districts at Pinj= 200 bar and Pinj = 220 bar infusion weights, although there was a change at all weight levels with enlarged mixtures. Compared with 180 bar, at 220 bar NOx fluxes increased by 1.62 percent. CO emissions were greater for all proposed fuel mixtures at various greater infusion weights at lower stacks. The reason for this is that under lower loads, total combustion concentrates with a larger discuss fuel fraction, which promotes cool combustion. However, the most intense NOx emission increased in proportion to the accumulation oxygen percentage in the proposed biodiesel mixture. The Taguchi technique with GRA has been used very effectively in optimizing the features of performance and emissions of piston-type IC engines coated with copper-chromium-zirconium alloy.
