The invention measures spatial (cylinder-to-cylinder) and temporal (cycle-to-cycle) EGR fluctuations using an optical probe that requires single-port access.
An apparatus, method and software for the detection of ammonia gas in an internal combustion engine environment using optical fiber based evanescent light absorption is described.
A wireless power transfer alignment system includes a floor-mounted coil and a vehicle mounted coil that, when magnetically coupled together, allows the transmission of power from the floor to the vehicle for wireless batter charging.
This invention disclosure provides details of winding techniques, structural design, and fundamental control concepts which result in improved performance, specific power, and/or power density of Isolated Multiple Flux Path (IMFP) reluctance motors.
The drive system includes electric machine and inverter. The cost of a drive system for vehicles is currently too high. It is over four times the DOE 2020 cost target. Permanent magnet (PM) is a major cost item in an interior PM machine.
This invention provides an alternative option to increase the power density by the additional smooth third-harmonic torque.
This invention discloses an electrical motor drive topology that can significantly reduce the inverter dc bus ripple currents and thus the requirement of the dc bus capacitance. This leads to a substantial reduction in the cost and volume of the inverter.
This particular invention enhances the physical embodiment of the ORNL AIMVEE/WIM physical device enabling the permanent anchoring of the pad to the pavement.
The current invention describes an engine cycle to substantially increase the thermal efficiency of internal combustion piston engine. The increased efficiency is a result of recovering heat primarily from the engine exhaust gases, and also from the engine coolant.
This particular invention enhances the physical embodiment of the ORNL AIMVEE/WIM physical device modifying the load cell foot strap that is located parallel to the edge of the transducer pad and perpendicular to vehicular travel.
