Revolution Speed Limiter for Engine Subjected to Large Load Variation
نویسندگان
چکیده
Engine speed limiters are safety devices to prevent the engine to exceed a predetermined high speed. The presented speed limiter is designed for large load variations which requires accurate and fast Air-Fuel ratio control. It is based on feedback linearization and on-line estimation of the load torque. Experimentations was done with a Sea-Doo r © watercraft powered by a Rotax r © four-stroke engine. A dSpace r © system was used to by-pass the engine ECU injector commands and to use those of the developed controller. Experimental results show that the developed controller performs better than usual ECU injection cut-off strategy. Copyright c ©2004 IFAC.
