Abstract

The air loss detection device has a device to detect the actual load/torque output of the engine control, and a comparer (26) of this value and the set value. If the detected actual value is below a certain threshold, a leak between the compressor and the engine cylinders can be assumed, and information on this is sent to a receiver (27) and a display device (28).
