An internal combustion engine system that converts thermal energy from an exhaust of an engine to mechanical energy includes a heat exchanger thermally coupled to an exhaust from an internal combustion process. The heat exchanger receives a heat transfer fluid therein. A generator is coupled to the heat exchanger. The heat transfer fluid expands and evaporates in the generator in response to heat from the exhaust of the internal combustion process. The expansion of the heat transfer fluid vapor converts thermal energy of the heat transfer fluid to mechanical energy.

High efficiency internal combustion engine

A method for use in generating power in an internal combustion engine from combustion of a fuel admixed with an oxidizing gas and operating cyclically with intentional ignition of a first fuel or with self-ignition of a second fuel which includes changing a volume of a combustion chamber from a fixed minimum volume to a fixed maximum volume wherein the maximum volume is greater than a critical volume. The critical volume includes a volume of the chamber filled with an oxidizing gas at an initial temperature and an initial pressure such that when the temperature is compressed from the critical volume to the minimum volume the gas reaches a maximum temperature and a maximum pressure causing detonation of a first fuel, or the gas exceeds a maximum temperature and a maximum pressure predetermined for self-ignition of a second fuel. A flow of the gas is controlled into the chamber so as to provide an upper limit on the amount of the gas which fills the chamber in each chamber-filling intake part of an engine cycle. The upper limit includes a mass less than an amount of a mass of the oxidizing mass in the critical volume.

An instrument for measuring sub-pico Tesla magnetic fields using a superconducting quantum interference device (SQUID) inductively coupled to an unshielded gradiometer includes a filter for filtering magnetically-and electrically coupled radio frequency interference (RFI) away from the SQUID. This RFI is principally coupled to the SQUID via the unshielded gradiometer. The filter circuit includes a resistor-capacitor (RC) combination interconnected to first and second terminals so that it is parallel to both an input coil of the SQUID and the gradiometer. In addition, a shielding enclosure is used to electromagnetically shield the filter circuit from the SQUID, and a method is employed to increase the impedance between the input coil and the SQUID without diminishing the overall sensitivity of the instrument.
