摘要:
A spark plug device includes a structure for modification of an arc, the modification including arc rotation. The spark plug can be used in a combustion engine to reduce emissions and/or improve fuel economy. A method for operating a spark plug and a combustion engine having the spark plug device includes the step of modifying an arc, the modifying including rotating the arc.

There is disclosed herein an apparatus for routing electrical signals in an engine having n cylinders and an intake manifold, one embodiment of which comprises: (1) a generally rigid housing generally conforming in shape with and being removably attachable to a top surface of the intake manifold; (2) at least n carrier members attached to the housing and extending outward therefrom, wherein each carrier member is arranged in general proximity with a respective cylinder; (3) a plurality of conductive circuit traces arranged on or within an underside or other surface of the housing and on or within each carrier member; and (4) at least one input/output connector for connection to at least one of an external signal source, an external power source, an external signal destination, and an external power destination, wherein each input/output connector is attached to the housing and is electrically connected to at least one of the circuit traces. Each circuit trace carried by each carrier member terminates in a termination electrically connectable with an electrical engine element, such as an ignition coil, an electronic fuel injector, a spark plug, and/or a glow plug.

Conductors supported integrally with engine structure such as air intake manifolds and the like provide interconnection between engine components without the need for separate conventional wiring harnesses. The conductors take their mechanical strength from the underlying physical object and thus can be lighter than a freestanding harness. Connectors allow traces to continue across points of mechanical interface between structural components and allow wiring of engine components to be accomplished in the same operation as their physical assembly.

Methods and apparatuses for laser ignition in an internal combustion engine. Laser radiation is directed to an ignition location within a combustion chamber with adaptive optics, and the position of the ignition location is adaptively adjusted during operation of the engine using the adaptive optics. Multiple ignition locations may be provided during a cycle of an internal combustion engine. A first pulse of laser radiation is directed to a first ignition location within a combustion chamber with adaptive optics, and a second pulse of laser radiation is directed to a second ignition location within the combustion chamber using the adaptive optics.

An engine control unit having electronic components and various circuits for controlling an engine is mounted on a portion substantially just above an intake manifold of the engine. An ignition coil circuit and an injector circuit are formed integrally in a case of the engine control unit. A connector for connecting a sensor circuit to the engine control unit and a harness connecting connector are formed on a peripheral wall surface of the case of the engine control unit.
