Abstract
The diminution of fossil fuels and stringent pollution norms obliging researchers to search for fuels that result in less pollution and the one that suits to power compressed ignition engines. In the current work the effect IOP (Injector opening pressure) and nozzle geometry on the performance and emission characteristics of diesel engine fueled by Castor oil methyl esters (CAOME) is reported. For a 5-hole nozzle at 240 bar IOP the highest brake power is obtained (27.32%). Peak pressure gradual upturn was observed when the IOP was varied from 210 bar to 240 bar and the peak value of pressure is 79 bar at IOP of 240 bar.
Highlights
The progress of any country mainly be influenced by on the available energy resources
Barajas Forero (2005), has studied the production of castor oil biodiesel by transesterification using NaOH catalyst and the results prove that it better suits for cold weather operation
The results shows that with sulfuric acid as catalyst with increase in reaction time from 30 minutes to 45 minutes resulted in decrease in viscosity from 16.56 cSt to 11.28cSt and further it observed that there is an increase in viscosity with increase in reaction time and optimum reaction temperature was found to be 55°C.By using NaOH as catalyst, with increase in reaction time from 30 minutes to 45 minutes results in decrease in viscosity from 21.57 cSt to 13.10 cSt and optimum reaction temperature was found to be 30°C which results in castor oil with lowest viscosity
Summary
The progress of any country mainly be influenced by on the available energy resources. With ever increase in energy consumption, rigorous pollution norms and depletion of fossil fuels resulted in need for huge investment in energy sector to fulfill the requirement and to investigate new sources of ecofriendly energy resources. Mechanization and modernization resulted in abrupt rise in energy demand and the exploration of the same which are mainly fossil fuel based. This situation resulted in search for new alternatives and one among them is oils obtained from green matter. Are in comparison with petroleum based fuels. These oils can be used in diesel engines with several modifications such as preheating to decrease viscosity, Varying IOP and injection timing.
