Experimental study the effect of diesel engine performance fuelled by waste tire oil- dexlite blends

Abstract

It well known that tire as a waste from vihicles susch as passengger car, truck and trailller. Indonesia country has enough potensial of tire waste, it was produced of about 11 millions ton per years. This phenomena could be serious environmental problem because tire waste was difficult dissolve by environment. It is needs to solve this issue by convert the waste tire to oil fuels. The main focus of this research to evaluate the performance of diesel engine fuelled by waste tire oil-dexlite blends. The physicochemical properties such as viscosity, density, calorific value and cetane number the waste tire fuel and its blends with dexlite were analysed. The experimental methode to determine engine performance by using the CI engine with variation of speed from 1500 rpm to 2100 rpm and waste tire-dexlite blends ratios at 10% (WTO-10), 20% (WTO-20) and 30% (WTO-30) of waste tire oil (WTO) and dexlite were utilized as a fuels. The CI engine with variation of speed from 1500 rpm to 2100 rpm was selected in order to determine the engine performance. The experimental results showed that the blending of waste tire oil with dexlite from 10% to 30% can operate with CI engine without any engine modifications. The results of this study revealed that maximum power and SFC were found to be 2.3 kW and 0.48 kg/kWh, respectively. Moreover, at the engine speed of 1900 rpm and a fuel blend of WTO-10 were found that to be optimal values of power and thermal efficiency which is similarly by using dexlite as fuel.
