摘要： Embodiments disclosed herein relate generally to systems and methods of operating internal combustion (IC) engines, and more specifically to systems and methods of starting compression ignition (CI) engines when the surrounding environment is significantly colder than the normal operating temperature of the engine (i.e., “cold-starting”). In some embodiments, the CI engine can include an ignition-assist device. In some embodiments, a method of operating a CI engine during cold-start can include opening an intake valve to draw a volume of air into the combustion chamber, moving a piston from a bottom-dead-center position to a top-dead-center position in a combustion chamber at a compression ratio of between about 15 and about 25, injecting a volume of fuel, the fuel having a cetane number of less than about 30, closing the intake valve, and combusting substantially all of the volume of fuel.

摘要： In a flame glow plug for a Diesel engine with an insert structure mounted on the plug body for the supply of fuel thereto, wherein the plug body includes in a vaporizing tube, a heating rod arranged in spaced relationship to the vaporizing tube such that an annular gap remains in which a vaporizing sieve is disposed and the heating rod extends axially beyond the vaporizing tube and is protected there by a flame tube firmly mounted on the plug and projecting into the intake airflow path when the glow plug is installed in an engine, the flame tube has circumferentially spaced air inlet openings and the vaporizing tube extends to the air inlet openings of the flame tube, the vaporizing tube further has a collar forming a narrow annular gap around the heating rod for supporting the vaporizing sieve and preventing flame backflashing through the gap and at least one row of openings arranged circumferentially below the collar.

摘要： To downsize an electromagnetic wave generation device in a plasma generation device that generates electromagnetic wave plasma by emitting to a target space an electromagnetic wave amplified by means of a solid state amplifying element. The plasma generation device includes the electromagnetic wave generation device that outputs the electromagnetic wave amplified by means of the solid state amplifying element, and an emission antenna for emitting the electromagnetic wave outputted from the electromagnetic wave generation device to the target space. The plasma generation device causes the emission antenna to emit the electromagnetic wave to the target space, thereby generating the electromagnetic wave plasma. The plasma generation device has a characteristic that an output waveform of the electromagnetic wave generation device has a peak during a rise, and is adapted to output the electromagnetic wave to the emission antenna without reducing the peak during the rise of the output waveform.

摘要： In a method for operating a laser device, which has a laser-active solid having a passive Q-switch, the laser device is acted upon using pumping light in such a way that a specifiable curve over time of the inversion density comes about in the laser-active solid, as a result of which an especially precise control of the time behavior is achieved during the generation of passively Q-switched laser pulses.
