摘要：
An internal combustion engine for a motor vehicle, having at least one adjusting device by means of which at least one compression ratio of the internal combustion engine is variably settable. At least one detection device is provided by means of which at least one signal (20, 22) which characterizes an actuation effort for setting the compression ratio is detectable. The invention further relates to a method for checking an adjusting device of such an internal combustion engine.
