Abstract
The present study analyzes emissions, by using different blends of diesel and Refined Sunflower oil (RSF) on Kirloskar Direct Injection 4-stroke Diesel engine, single cylinder air-cooled, 4.4 kW, constant speed at 1500 rpm, compression ratio 17.5:1, Methyl Esters of refined sunflower oil (BRS) was transesterified with sodium meth oxide before blending with diesel. The main objective of this study is to measure the NO x , CO, HC, and Exhaust temperature by varying the Injection pressure and the load. The experiments were conducted with various blends of diesel (BRS10, BRS30, and BRS40) at different pressures (180 bar, 210 bar,&240 bar) and at different loads (0%, 25%, 50%, 75%, 100%). A 3-hole nozzle was used to inject the fuel. The Emission results were studied using AVL gas analyzer. The results show that there is an increase in CO, marginal increase in NO x and decrease in HC.
Highlights
In the Present scenario, the depleting fossil petroleum fuel, with ever increase in fuel price and increase in pollution level hazards to the environment that results due to engine exhaust, forces the usage of alternate fuels
The combustion and emission results in base line fuel and the emission of smoke and nitrogen oxide measured at the engine exhaust while using cottonseed or sunflower oil in different proportions with two speeds and 3 loads tested by Rakopoulos et al [3] the blends of sunflower, cotton seed, corn and olive used in six cylinders turbo charged heavy duty DI, Mercedes benz mini bus engine with the amount of two speed and three load conditions with neat diesel resulted in no changes in the thermal efficiency
For production of pure methyl ester, without any soap content, methanol is added to the preheated oil with catalyst at cold temperature and the mixture is heated to the order of 70°C to 80°C during the transesterification process of oil to reduce viscosity
Summary
In the Present scenario, the depleting fossil petroleum fuel, with ever increase in fuel price and increase in pollution level hazards to the environment that results due to engine exhaust, forces the usage of alternate fuels. The experiments on the DI diesel Perkinson engine were conducted by Dorado et al [5] by using reused olive oil methyl ester to study the effect on combustion efficiency. A lower energy rate was showed in the palm oil combustion, done by Tashtoush et al [6] It was more efficient and higher rate of combustion (66%) seen in burning biodiesel, and the same for diesel combustion is 56% This is because of the properties like high viscosity, less volatility with density. A review was done by Shereena et al [9] using catalyst along with methanol in the transesterification process, which results in varying fatty acid content of the biodiesel This could be a good alternative fuel for diesel
