Exhaust emissions of diesel engine with CuNO3 nano additive and butanol-diesel blends

Abstract

This experimental study was focused on use of CuNO3 as a fuel additive with butanol-diesel blends in diesel engine and its effects on fuel specifications and emission characteristics. With this purpose, CuNO3 nano additive was mixed with diesel-butanol and each test fuel was analyzed to determine fuel specifications (density, viscosity, Cetane number, heating values and copper strip corrosion). A four stroke, four cylinder direct injection diesel engine was conducted to perform the test fuels. In conclusions, CuNO3 nano additive with diesel-butanol blends improved the fuel specifications and exhaust emission characteristics of diesel engine.
