Abstract
The invention relates to a lubricating system for an internal combustion engine (1). The system includes a first conduit means (7) connecting a lubricant supply source (5) to the internal combustion engine (1) for supplying lubricant to the internal combustion engine (1). According to the invention, the system further includes a second conduit means (8) connecting a gas supply source to the first conduit means (7) for supplying gas to the first conduit means such that gas bubbles are formed in the first conduit means (7). A sensor (3) detects whether lubricant or whether gas is present in a certain part of the first conduit (7). The certain part being located downstream the connection of the second conduit means (8) to the first conduit means (7). A control unit (6) is connected to the sensor (3), which control unit (6) is arranged to determine whether lubricant is flowing through the first conduit means (7) or not, in response to the detections of the sensor (3). The invention also relates to an internal combustion engine, to a power tool and to a method for providing lubricant to an internal combustion engine.
