  • Cylinder detection in a four-stroke internal combustion engine
    Patent number: 11585287
    Abstract: An arrangement for cylinder detection in a four-stroke internal combustion engine is disclosed. The arrangement comprises a first disc connected to a crankshaft, the first disc comprising a first mark (M11-M13) within each an interspace angle (?), and a second disc connected to a camshaft and comprising one second mark (M21-M26) per number of cylinders. The first mark (M11-M13) is arranged on a first disc, or the plurality of first marks (M11-M13) are arranged in relation to each other on the first disc, and the second marks (M21-M26) are arranged in relation to each other on the second disc such that for each interspace angle (?) the relevant first mark (M11-M13) is detectable by a first sensor and the relevant second mark (M21-M26) is detectable by a second sensor at different relative rotational positions between the first disc and the second disc.
