  • Patent number: 9284865
    Abstract: A method includes energizing a solenoid valve of a hydraulic control system according to a predetermined timing schedule to move a valve member of the solenoid valve. The solenoid valve is operatively connected to the switching component by a fluid control passage, such as a passage in an engine block, to deliver pressurized fluid from a supply passage when the valve member moves to switch the switching component from a first mode to a second mode. An operating parameter of the control system is measured. The operating parameter may be a period of time over which the valve member moves, or a sensed operating parameter of the fluid, such as pressure or temperature. The measured parameter is then compared with a predetermined parameter. Energizing of the solenoid valve is then adjusted based on the difference.

  • Patent number: 9284875
    Abstract: Systems are provided to providing water to the bore bridges of a cylinder block that contains an oil cooling system. An oil-cooled cylinder block may be desirable to aid in rapidly increasing engine temperature during engine warm-up, but high local temperatures may exist in the bore bridges in between adjacent cylinders, thereby leading to adverse performance. To control the high local temperatures while maintaining rapid engine warm-up, systems are proposed to provide water coolant from the cylinder head into cross-drilled passages located in the bore bridges of the cylinder block while cooling the rest of the cylinder block with oil or a different coolant.

  • Patent number: 9284879
    Abstract: A piston for an internal combustion engine, including a body configured to collaborate with walls of a cylinder of axis of revolution C in which the piston is configured to slide along the axis C. The piston includes a transverse face including a central pip, a peripheral ring, and a bowl of axis of revolution B extending from the central pip towards the peripheral ring to which it connects at a lip. The bowl includes, in substantial vertical alignment with the lip, a torus in profile, of maximum radius capable of guiding fuel injected under the lip in a region of a re-entrant zone towards the central pip. The tip of the pip lying on the axis of revolution B of the bowl rises to a height that is a distance of between 4.8 mm and 5.5 mm, or equal to 5.4 mm, below the level of the peripheral ring.

  • Patent number: 9284880
    Abstract: Methods and systems are provided for purging condensate from a charge air cooler to an engine intake. During an engine deceleration event, the vehicle is downshifted into a lower gear to increase RPM and airflow through a charge air cooler to purge stored condensate to the engine intake. By delivering condensate while an engine is not fueled, misfire events resulting from ingestion of water are reduced.

  • Patent number: 9284885
    Abstract: A method of optimizing the use of an aircraft power plant having at least one engine operating within a performance envelope covering at least a first rating and a second rating, the first rating presenting a first power (P1) usable over a predetermined first time interval (D1), the second rating presenting a second power (P2) greater than said first power (P1), the second power (P2) being usable continuously over a predetermined second time interval (D2). Thus, while the engine is developing a third power (P3) that is both greater than the first power (P1) and less than or equal to the second power (P2), a potential first duration of utilization (?T) of continuous use of the second power (P2) is determined and displayed, the first duration of utilization (?T) elapsing at a speed that is variable and that depends on said third power (P3).
