The Effect of RME-1-Butanol Blends on Combustion, Performance and Emission of a Direct Injection Diesel Engine

The main objective of this study was assessment the performance, emissions and combustion characteristics a diesel engine using RME–1-butanol blends. In assessing process, great importance placed on evaluating stability process. Not only were typical COVIMEP indicators assessed, but also non-burnability characteristic stages: ignition delay, time 50% heat release end combustion. evaluation process based analysis release. tests carried out 1-cylinder operating at constant load. Research mixture RME 1-butanol for entire range shares both fuels up to 90% energetic fraction. participation butanol in with increased in-cylinder peak pressure rate. With increase share there noted decrease specific energy consumption an efficiency. improved stability. There NOx CO soot emissions. can be power by blend 80% butanol.
