摘要： An ignition circuit and a method of operating an igniter (preferably a traveling spark igniter) in an internal combustion engine, including a high pressure engine. A high voltage is applied to electrodes of the igniter, sufficient to cause breakdown to occur between the electrodes, resulting in a high current electrical discharge in the igniter, over a surface of an isolator between the electrodes, and formation of a plasma kernel in a fuel-air mixture adjacent said surface. Following breakdown, a sequence of one or more lower voltage and lower current pulses is applied to said electrodes, with a low “simmer” current being sustained through the plasma between pulses, preventing total plasma recombination and allowing the plasma kernel to move toward a free end of the electrodes with each pulse.

摘要： A system using electrical discharge plasma (EDP) for treating a liquid, such as water or waste water to degrade or destroy polar contaminants such as per- and polyfluoroalkyl substances (PFAS) compounds, the system includes a sealed process tank and multiple submerged EDP channels stacked horizontally. Each EDP channel consists of a cathode and an anode, a gas hood, and a gas diffuser. The basic submerged EDP channel is bounded by a plate at the bottom and a submerged gas hood at the top which creates a gas headspace, and hence, a local water surface to provide a local gas/liquid interface in each channel. The cathode lies above the local water surface and anode lies below the local water surface. Each EDP channel may have a gas diffuser at the bottom of the EDP channel for introducing a process gas into the liquid creating bubbles that carry contaminants in the liquid to the local gas/liquid interface. An electrical discharge arcs between the cathode and the anode to generate a plasma used for destruction of contaminants in the water or wastewater at the local gas/liquid interface.

摘要： A nozzle assembly for generating an atmospheric plasma jet includes an inlet, through which the jet can be introduced into the nozzle assembly, and a channel connected to the inlet so that the plasma jet introduced is conducted through the channel. Multiple nozzle openings are provided in the channel wall along the channel, through which a plasma jet can exit the assembly. The cross section of the channel in the region of a nozzle opening is shaped in such a way that a virtual medial plane runs between a virtual first tangent plane of the cross section through the nozzle opening and a virtual second tangent plane of the cross section opposite thereto and parallel to the first tangent plane divides the cross section into a first cross-sectional area at the nozzle opening. The cross-sectional surface of the first cross-sectional area differs from the cross-sectional surface of the second.

摘要： A method includes: receiving a first signal from a first sensor at a first filter and preventing passage of a first portion of the first signal via the first filter. The first portion of the first signal is at a first RF. A second portion of the first signal is indicative of a first temperature of a first electrode in a plasma chamber. The method further includes: outputting a second signal from the first filter; receiving the second signal at a second filter; and preventing passage of a portion of the second signal via the second filter. The portion of the second signal is at a second RF. The second RF is less than the first RF. The first filter and the second filter are implemented on a printed circuit board. The method further includes adjusting a temperature of the first electrode based on an output of the second filter.

摘要： This invention relates generally to novel methods and novel devices for the continuous manufacture of nanoparticles, microparticles and nanoparticle/liquid solution(s). The nanoparticles (and/or micron-sized particles) comprise a variety of possible compositions, sizes and shapes. The particles (e.g., nanoparticles) are caused to be present (e.g., created) in a liquid (e.g., water) by, for example, preferably utilizing at least one adjustable plasma (e.g., created by at least one AC and/or DC power source), which plasma communicates with at least a portion of a surface of the liquid. At least one subsequent and/or substantially simultaneous adjustable electrochemical processing technique is also preferred. Multiple adjustable plasmas and/or adjustable electrochemical processing techniques are preferred. The continuous process causes at least one liquid to flow into, through and out of at least one trough member, such liquid being processed, conditioned and/or effected in said trough member(s). Results include constituents formed in the liquid including micron-sized particles and/or nanoparticles (e.g., metallic-based nanoparticles) of novel size, shape, composition and properties present in a liquid.
