Engine torque estimating arrangement has first stage for estimating torque when fuel feed blocking device inactive, second stage for estimating torque when fuel feed blocking device active

摘要

The engine torque estimating arrangement has a fuel feed blocking device (26) that is active during a defined engine (50) operating condition and an engine torque estimation device (21) with a first stage (22) for estimating engine output torque when the fuel feed blocking device is inactive and a second stage (24) for estimating the torque when the fuel feed blocking device is active. AN Independent claim is also included for the following: (a) a method of estimating engine torque.
