<p>The angular deceleration (dω/dt) of an output shaft after switching from a driving state, in which an engine is driven by burning fuel that is supplied, by a fuel supplying device, into a space in an engine cylinder, to a measuring state, in which deceleration is caused by suppressing the combustion of fuel in the engine cylinder space, is measured, and the friction loss in an engine is found based on the measured friction torque (Tf) of the engine found by a formula (Tf=It×dω/dt), where (It) is the moment of inertia for the entire drive system of the engine, and the friction torque correction volume corresponding to the work correction volume resulting from the post-combustion dripping generated in the engine cylinder space after switching from the driving state to the measuring state.</p> |
