Vacuum management system on a variable displacement engine |
摘要 |
A vehicle reciprocating piston, variable displacement internal combustion engine arrangement 7 is provided. The arrangement 7 includes a first cylinder group 12. A second selectively deactivatable cylinder group 14 is also provided. A manifold 18 is provided which is exposed to at least one of the cylinder groups. A vacuum system 24 is powered by manifold 18. An engine controller 16 is cognizant of a vacuum level of the vacuum system 24. The controller modifies operation of the engine arrangement 7 to increase a vacuum level of the manifold 38 when the second cylinder group 14 is deactivated and the vacuum system 24 vacuum level is lower than a predetermined level
