Capacitive shift-force sensor
The capacitive shift-force sensor is made in the form of a deformable casing defined by two parallel rigid plates spaced from each other and interconnected by two deformable members. The sensor is provided with two capacitors, wherein one capacitor plate of each capacitor is rigidly connected to one rigid plate and the other capacitor plate is rigidly connected to the other rigid plate. In an unloaded state of the sensor, capacitor gaps of both capacitors are equal and the capacitors have the same capacitive characteristics. However, when one of the rigid plates is maintained immobile and the other one is shifter under the effect of an applied shift force, the capacitor gaps of the capacitors, and hence, the capacitive characteristics of the capacitors, change differently, and with the use of a differential amplifier this difference is measured and recalculated into the value of the applied shift force. |

Dual stage internal combustion engine aftertreatment system using exhaust gas intercooling and charger driven air ejector
An exhaust aftertreatment system includes a first stage catalytic converter, a second stage catalytic converter, and a conduit extending from the first stage catalytic converter to the second stage catalytic converter. The conduit passes through an exhaust gas intercooler, between the first and second stage catalytic converts, that reduces the temperature of the exhaust to about 300° F. to about 500° F. Air is ejected into the exhaust conduit to increase the oxygen concentration in the exhaust before it passes through the second stage catalytic converter. The air can be ejected from an air ejection conduit that extends to an engine charger compressor or a compressed air conduit that extends from the engine charger compressor, such as a turbo charger and/or a supercharger, to the engine. A gas particulate filter can be disposed in the exhaust conduit or it can be integrated with the second stage catalytic converter, for example as a catalyzed gas particulate filter. |
