LOW FRICTION CAMSHAFT WITH ELECTRIC PHASER |
| 摘要 |
An exemplary engine assembly includes a crankshaft, and a camshaft having cam lobes mounted thereon. The cam lobes are configured to provide lift to respective devices as a function of a rotation of the camshaft. The cam lobes are circumferentially offset from one another such that a timing of operation of the lift is different for each of the at least two cam lobes. The assembly includes at least one roller bearing coupled to the camshaft, and an electric cam phaser configured to alter the timing of the camshaft with respect to the crankshaft as a function of engine operation. |

1. An engine assembly comprising:
a crankshaft; a camshaft having at least two cam lobes mounted thereon, the at least two cam lobes configured to provide lift to respective devices as a function of a rotation of the camshaft, wherein the at least two cam lobes are circumferentially offset from one another such that a timing of operation of the lift is different for each of the at least two cam lobes; at least one roller bearing coupled to the camshaft; and an electric cam phaser configured to alter the timing of the camshaft with respect to the crankshaft as a function of engine operation. |
