Performance and Emission Characterstics of Single Cylinder Diesel Engine using Transformer Oil and Pine Oil Blend with Butanol Additive

Abstract

Reuse and recycling are better options to derive energy or value added products from waste substances and to minimize the disposal problems. Transformer oil is generally used as a coolant in welding transformers, power transformers and electromotive units. After a prolonged use in these devices, the transformer oil becomes waste and is disposed of. The disposal of used transformer oil causes an environmental pollution. However, the used transformer oil has properties that are similar to that of diesel fuel with a marginally higher viscosity and lower calorific value. The aim of the primary investigation is to reuse the used transformer oil as a possible source of energy to run a small powered, single cylinder, four stroke, and direct injection diesel engine with different compression ratios to study the performance and emission characteristics of used transformer oil. The results are analyzed and compared with diesel fuel operation.
