Abstract: Combustion air for use in an engine is normally compressed by a compressor which adds heat during the process of increasing the density of the combustion air. To decrease the heat content of the combustion air, an aftercooler is used. When compressing combustion air to a higher density, the combustion air is compressed by a first compressor section to a first preestablished pressure and temperature and by a second compressor section to a second preestablished pressure and temperature. To decrease the heat content of the highly compressed dense combustion air, a first aftercooler having an air to liquid configuration is used and a second aftercooler having an air to air configuration is used.

Abstract: A combined piezo and solenoid actuator are on separate electrical circuits that are coupled via a transformer. The solenoid actuator includes a first set of electrical windings that are arranged as a transformer with a second set of electrical windings that are a portion of a piezo actuator. Current supplied to the solenoid causes a brief induced voltage in the piezo circuitry that causes the piezo stack to expand and push the actuator member with a relatively large force over a short distance. As the magnetic flux of the solenoid continues to build, it applies an electromagnetic force to the armature to push the actuator member through a second larger distance. The combined piezo solenoid actuator finds potential application in valves that require high initial opening forces but also travel distances much larger than that practical with a piezo acting alone.
