An Assessment of Performance of Compression Ignition Engine Fueled with Recycled Waste Engine Oil Waste Cooking Oil and Waste Plastic Oil as Fuel

Abstract

<div class="section abstract"><div class="htmlview paragraph">Using the recycled waste oils are to be focused for the protection of environment by reducing the land pollution and disposal costs. This study is to use the recycled waste engine oil, waste cooking oil and waste plastic oil along with Bio-butanol from the waste cut vegetables and fruits. Initially, properties and solubility were tested for choosing a suitable blend for fueling into diesel engine from various proportions. These three blends from the base of three waste oils are then tested by modifying and standard engine operating parameters for performance.</div><div class="htmlview paragraph">The properties tests results as 18% of waste engine oil (by volume) with bio-butanol, 16% of waste cooking oil (by volume) with bio- butanol and 24% of waste plastic oil (by volume) with bio-butanol are found competent</div><div class="htmlview paragraph">for fueling engine. These blends produces low efficiency in lower brake powers and the emissions of smoke, hydrocarbons and carbon monoxide are also higher during the operation under standard parameters. To upkeep this parameters such as nozzle pressure, timing of fuel injection and the ration of compression are optimized by orthogonal array method. This method arrived for the optimal levels as 19:1 compression ratio, 210 bar nozzle pressure and 26 degree of timing injection by considering the base as efficiency of the engine. By deployment of these parameters the engine produces similar efficiency, thermal energy release, pressure of cylinder, emissions oxides of nitrogen under higher brake powers. This utilization saves the cost of disposal and the quantity of fossil fuel resources from other countries to India for the use as fuel for compression ignition engines.</div></div>
