Title:
ENGINE MEASUREMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2006/120728
Kind Code:
A1
Abstract:
[PROBLEMS] To provide an engine measurement device for determining the mechanical loss of an engine for a short time. [MEANS FOR SOLVING THE PROBLEMS] The engine measurement device includes a detector (2) for measuring the individual pieces of time series data containing at least the speed and the output torque of an engine (10) in a transient state while the engine (10) being run in combustion by the control of an engine control unit (3), a torque operation unit (64) for calculating the engine torque on the basis of the time series data of the engine speed and the output torque, and a model operation unit (66) for modeling the engine torque as functions of the engine speed and a fuel injection time. This model is used to calculate both a fuel torque generated by the combustion run of the engine and a mechanical loss torque or the difference between the engine torque and the fuel torque.
