  • Publication number: 20220241847
    Abstract: A mold package for forming a cast device such as an engine block is described. The mold package includes a profiled chill and a mold core assembly that is disposed on the profiled chill. The mold core assembly defines a plurality of bulkheads of the engine block. The profiled chill includes a first chill portion having a second chill portion and a plurality of third chill portions arranged thereon, wherein the second chill portion is a semicylindrical element. The third chill portions are arranged to be adjacent to the plurality of bulkheads of the engine block.

  • Publication number: 20140321966
    Abstract: A packaged vacuum pump and oil pump for use in a vehicle generally includes an oil pump module and a vacuum pump module. The oil pump module is configured to circulate oil, and is fitted to a first drive shaft configured to transmit torque to the oil pump module. The vacuum pump module is configured to generate a vacuum, and is fitted to a second drive shaft configured to transmit torque to the vacuum pump module. The packaged vacuum pump and oil pump also includes a clutch. The clutch connects the first drive shaft and the second drive shaft, and is configured to transfer torque from the first drive shaft to the second drive shaft when the clutch is engaged. The clutch may be a hydraulic clutch configured to receive a pressurized fluid, which may be oil received from the oil pump module, to engage the clutch.

  • Patent number: 7431023
    Abstract: A positive crankcase ventilation system for an internal combustion engine is disclosed. The system includes an engine having a cylinder air intake system connected to associated cylinders and a filtered air inlet to a crankcase for admitting air to mix with crankcase vapors. A throttle is disposed in the cylinder air intake system for controlling airflow to the associated cylinders. The system further includes a venturi nozzle having an inlet and an outlet. The venturi nozzle inlet is connected to the crankcase for receiving the mixture of filtered air and crankcase vapors. The venturi nozzle outlet is connected to the cylinder air intake system at a location subject to variable intake vacuum pressure between the throttle and the cylinders to allow the mixture of filtered air and crankcase vapors to be drawn into the inlet air passing to the cylinders downstream of the throttle.
