Experimantal Investigation on Engine Emissions Performance of the Volvo TD 60B Engine Running on MK1 as well as on a Mixture of MK1 and Ethanol (E15)

Report, 1994

The test was aimed at investigation of the engine performance and its emissions, when the engine runs on E15, as compared to conventional diesel fuel MK1. The method used was engine running according to the specifications of the european test cycle ECE R49. 80th fuels: conventional and E15 were used. The general performance and exhaust gas emissions of the engine were recorded and evaluated according to the regulations concerning the control of air pollution from heavy duty motor vehicles (A 30 - Regulation). The test engine was a direct injected, turbocharged diesel engine Volvo TD 608. The engine, which is rated at 136 kW at 2800 rpm and 540 Nm at 1900 rpm, has been operating for years in the engine laboratory test rig of the Thermo and Fluid Dynamics Department. Running on diesehol fuel E15 with 0.6 % Dalco - E emulsifier reagent, the Volvo TO 60B turbocharged diesel engine maintain a good performance with reduction of the NOx emission levels and smoke density. The expected reduction of HC, ca and specific fuel consumption has, however, not been found.
