Abstract
In order to determine the quality of fuel in an auto-igniting internal combustion engine, a defined fuel amount is injected at defined crank shaft angles during a deceleration fuel shut-off phase of the internal combustion engine. The thereby created crankshaft torque contribution is detected and an absolute or relative measure is determined for the fuel quality thereof.
