Abstract
An experimental study is accomplished to assess the influences of methanol, ethanol and diethyl ether as additives to Karanja oil blends on the performance analysis of a four-stroke VCR-CI single cylinder diesel engine. The fuels considered for testing is denoted as B20 (20% karanja oil and 80% petrodiesel by volume), B20+5%DEE (5% diethyl ether, 20% karanja oil and 80% petrodiesel by volume), B20+5%E (5% ethanol, 20% karanja oil and 80% petrodiesel by volume), B20+5%M (5% methanol, 20% karanja oil and 80% petrodiesel fuel by volume), B20+10%DEE (10% diethyl ether, 20% karanja oil and 80% petrodiesel by volume), B20+10%E (10% ethanol, 20% karanja oil and 80% petrodiesel by volume) and B20+10%M (10% methanol, 20% karanja oil and 80% petrodiesel by volume) respectively. The fuel injection pressure is retarding 20 bar and advancing 20 bar and 40 bar from the standard injection pressure (fuel) of 200 bar which gives the injection pressures of 180, 220 and 240 bar. Analysis of performance parameters is investigated by the IC Engine analysis software which has been coupled with the VCR Engine. The outcome of data of these blends is to be associated with the petrodiesel. At higher engine load, performances of all tested fuels are almost same and comparatively diethyl either is more competent than standard diesel at 220 bar fuel injection pressure. As higher injection pressure (240 bar) and lower injection pressure (180bar) is giving a lower performance when related to standard diesel fuels. The experimental results depicted that the lower contents of diethyl ether and methanol along with karanja oil blend is more efficient when compared to petrodiesel ant it can be a substitute for the petrodiesel without any alteration in diesel engines.
