Spark ignition engine model building - an identification approach to throttle–torque response. (5th August 2014) - Morris, R.L.
A rapidly obtained low–order sampled data description of the output response of driveshaft torque to throttle opening is described. Based upon a sampling interval of one engine revolution, the resulting fourth–order dynamic model is applicable over the range of 600–2000 rpm (vehicle speed 0–60 mph) for a 5.7 litre feedback carburetted engine and automatic transmission. Physical principles are used to obtain a block diagram of the system, and Landau's hyperstable identification algorithm is then used to determine the parameters of the model.
