    摘要： A spark-ignition, air-compressing, internal combustion engine having a combustion chamber in the shape of a body of revolution with a constricted opening in the piston crown. The injection nozzle is located in the cylinder head near the edge of the combustion chamber and the spark plug, opposite the injection nozzle, extends into the combustion chamber at the top dead center position of the piston. Mixture formation is predominantly by deposition of the fuel on the combustion chamber wall. In such an internal combustion engine, it is desired in applying the concept to a supercharged engine to satisfy the enhanced requirements with respect to mixture formation reliably in all ranges of operation, whereby a further improvement of ignition stability is also to be provided. This is essentially achieved by the special shape and proportioning of the combustion chamber, and in particular by the use of two arcs to form the side wall thereof, and a third arc, which joins the side wall, to form the bottom.

    摘要： A conditioned air delivery system is provided for parked aircraft. The system can accommodate elevated thermal loads while maintaining operation, albeit with reduced flow rates or slightly elevated temperatures. When temperature set points are not reached or cannot be maintained, a second compressor of a refrigeration unit is operated in parallel with a first compressor. When refrigerant pressure becomes excessive, a second fan is operated that is associated with a condenser of the system. Still higher pressures, indicative of higher thermal loads, can cause the system to shut down operation of one of the compressors, reducing the overall cooling capacity of the system, while maintaining the supply of refrigerated air to the aircraft. The airflow may be reduced to maintain an air temperature at or near the desired temperature. Coordination of several parallel and redundant refrigeration units may be provided with a single blower and coordinated control.
