摘要： A quarter wave coaxial cavity resonator for producing corona discharge plasma from is presented. The quarter wave coaxial cavity resonator has a folded cavity made of opposing concentric cavity members that are nested together to form a continuous cavity ending in a aperture. A center conductor with a tip is positioned in the cavity. The folded cavity advantageously permits the coaxial cavity resonator to resonate at a lower operating frequency than an unfolded quarter wave coaxial cavity resonator of the same length. Embodiments of the quarter wave coaxial cavity resonator use narrower apertures to reduce radiative losses, and include center conductors that are reactive load elements, such as helical coils. When a radio frequency (RF) oscillation is produced in the quarter wave coaxial cavity resonator, corona discharge plasma is formed at the tip of the center conductor. The corona discharge plasma can be used to ignite combustible materials in combustion chambers of combustion engines.

摘要： An apparatus and method for igniting combustible materials in a combustion chamber of a combustion engine using corona discharge plasma from a quarter wave coaxial cavity resonator. A tapered quarter wave coaxial cavity resonator is adapted to mate with the combustion chamber. The quarter wave coaxial cavity resonator is coupled with an energy shaping means, or waveform generator, that develops the appropriate waveform for triggering radio frequency oscillations in the quarter wave coaxial cavity resonator. A loop coupling is angularly positioned within the quarter wave coaxial cavity resonator to match impedances between the quarter wave coaxial cavity resonator and the energy shaping means, or waveform generator. Radio frequency oscillations produce a standing wave in the quarter wave coaxial cavity resonator and a corona discharge plasma develops near the center conductor. The corona discharge plasma developed near the center conductor ignites the combustible materials in the combustion chamber of the combustion engine.

摘要： An internal combustion engine including a pre-chamber connected to a pre-chamber feed conduit for supplying the pre-chamber with a fuel (F), and a main combustion chamber. Fuel (F) in the main combustion chamber can be ignited by an ignition flare which passes from the at least one pre-chamber into the at least one main combustion chamber and which is produced by ignition of fuel (F) in the pre-chamber. At least one valve can be open-loop or closed-loop controlled by an open-loop or closed-loop control device depending on a parameter characteristic of a change in a power produced by the internal combustion engine, and/or by which a pre-chamber fuel flow directed through the pre-chamber feed conduit to the at least one pre-chamber can be at least partially diverted into a volume separate from the at least one pre-chamber.

摘要： The size of the plasma produced by a plasma-generating device that generates plasma using electromagnetic (EM) radiation is enlarged. The plasma-generating device has an EM-wave-generating device that generates EM radiation, a radiation antenna that emits the EM radiation supplied from the EM-wave-generating device to a target space, and a receiving antenna located near the radiation antenna. The receiving antenna is grounded such that an adjacent portion that is close to the radiation antenna has a higher voltage while the EM radiation is emitted from the radiation antenna. The plasma-generating device generates plasma in the target space near the radiation antenna and the adjacent portion by emitting EM radiation from the radiation antenna.

摘要： A plasma oil-free ignition system in oxygen enriched environment comprises a plasma generator and a burner. The plasma oil-free ignition system comprises a sleeve group coaxially arranged with the burner, and the sleeve group comprises multiple coaxially sleeved sleeves. Annular spaces are formed between adjacent sleeves and between the sleeves and the burner. Oxygen ducts are arranged on the sleeves, and oxygen ducts are arranged on the burner. Plasmas jetted by the plasma generators form a local high temperature zone filled with high temperature plasma and pulverized coal air flow. A certain amount of oxygen is fed to the burner through the oxygen duct therein to form local oxygen enriched zones in the annular spaces and the subsequent adjacent spaces through which air flows, thus realizing oxygen enriched combustion of volatile matters or coke or mixture thereof, and combustion the pulverized coal air flow more intensely to release more heat so as to ignite the primary air pulverized coal air flow quickly and burn the pulverized coal air flow stably. The invention has simple structure, is applicable to different coal types, especially applicable to the plasma oil-free ignition system in oxygen enriched environment of coal types with low volatile matters.

摘要： A process is provided for improving combustion control and fuel efficiency in rotary and reciprocating IC engines by enabling leaner combustion at higher compression ratios using less heat for ignition. Embodiments employ secondary chambers of minimal total volume within a cylinder periphery. These chambers communicate with a main chamber via conduits and enable a radical ignition (“RI”) species generation and supply process that starts in earlier cycles to be augmented and used in later cycles. Measures regulate the RI species generated and provided to the main chamber. These species alter dominant chain-initiation reactions of the combustion ignition mechanism. Also employed when preferable are fluids of higher heat of vaporization and volatility but lower ignitability than the fuel. This process improves combustion in radical ignition engines and radical augmented spark and compression ignition engines.
