摘要 |
The invention relates to an internal combustion engine comprising at least one first camshaft (2) and at least one second camshaft (3). Said camshafts (2, 3) are interlinked via a coupling gear (4), the first camshaft (2) being rotatable by a first phase shifter (5). The aim of the invention is to reduce the power of friction in the traction mode with minimum complications. For this purpose, the second camshaft (3) can be rotated by a second phase shifter (6) in such a manner that phase-shift of the second camshaft (3) is the result of the sum of adjustment movements of the two phase shifters (5, 6). |
