FIELD: engines and pumps.SUBSTANCE: internal combustion engine has element 110 fixed relative to crankshaft 32 and having multiple identical marks 110a and at least one mark 110b other than the former revolving about said crankshaft 32, crankshaft rpm transducer 111 and element 110. Signal is generated for every of said multiple marks 110a passing by said transducer 111. Note here that only for those signals that are generated for preset identical marks 110a ahead and/or behind of different mark 110b in response to appropriate interrupt signal.EFFECT: higher precision and reliability.9 cl, 6 dwg |
