Variable compression ratio control system for internal combustion engine |
摘要 |
A variable compression ratio control system for an internal combustion engine includes a lubrication system for selectively providing lubricating oil to connecting rods within the engine at either a lubrication pressure or at a control pressure. The oil is provided to compression ratio adjusters so as to cause the adjusters to move from one compression ratio to another, to achieve a desired change in compression ratio. A lubricating pump provides lubricating oil to the connecting rods through the lubrication system. The lubricating pump is selectively operable at one of a lubricating pressure and a control pressure by means of a control valve which is integral with the lubricating pump.
