Automobile internal combustion engine testing method, involves detecting air flow through air inlet channels for each cylinder bore during rotation of engine crankshaft via electric motor

摘要

The testing method has an electric motor coupled to the engine crankshaft (5) and a pressurized air source coupled to the air inlet channels (7) for each cylinder bore (2), with detection of the air flow through the air inlet channels during the rotation of the crankshaft by the electric motor at a relatively low rotation rate.
