Method and apparatus for engine torque disturbance reduction during cranking |
摘要 |
An internal combustion engine's start-up torsional disturbances are reduced by drawing down intake manifold pressure prior to engine cranking. In a preferred arrangement, a secondary air injection reaction pump is adapted for evacuating the intake manifold to effect the desired draw down of the intake manifold pressure. |
