Impact of the Proportional Factors of Electronic Speed Governor on Diesel Engine Performance 2001-01-0265

In the paper some experimental results concerned the influence of some electronic speed governor parameters on efficiency, exhaust smoke, exhaust emission, and dynamic behavior of Diesel engine, have been presented. The research object was a six-cylinder direct injection Diesel engine (100 kW at 2600 rpm, 6.54 dm3 swept volume) with electronically controlled in-line fuel injection pump.
Impact of proportional intensifying of fuel charge in relation to engine speed on engine performance has been studied. Four experimental tests were carried out for following engine operational conditions: idle, acceleration, rapid torque changes, and cycling torque changes. Following parameters have been analyzed: changes in engine speed, changes and vibrations of fuel rack, exhaust smoke, CO, HC, and NOx emissions, and some dynamic parameters. As the result, significant influence of the proportional factor value of electronic speed governor has been proved. It has been concluded that the proportional factor has different qualitative and quantitative impacts on the considered parameters. It has been shown how the proportional factor values should be chosen according to Diesel engine requirements.
