Abstract: In a plasma generation device that generates electromagnetic wave plasma by emitting electromagnetic waves in a target space, the electromagnetic wave plasma is generated in a plurality of locations with a simple configuration and relatively low electromagnetic wave energy. The plasma generation device is provided with an antenna that emits electromagnetic waves supplied from an electromagnetic wave generator in the target space, a discharger that forcibly discharges free electrons from gas molecules in the target space, and an electric field concentration member that concentrates electric field of the electromagnetic wave emitted from the antenna. The electric field concentration member is arranged in non-contact relationship with the antenna. The plasma generation device causes the discharger to discharge free electrons and the antenna to emit electromagnetic waves, thereby generating electromagnetic wave plasma in the vicinity of the antenna and in the vicinity of the electric field concentration member.

Abstract: An embodiment of a plasma ignition system for an internal combustion engine having up to N cylinders includes a power splitter, N phase shifters, N amplifiers, a power combiner network, and up to N radiation devices. The power splitter divides an input RF signal into N divided RF signals. Each phase shifter applies one of multiple pre-determined phase shifts to one of the N divided RF signals to produce N phase shifted RF signals. The N amplifiers amplify the N phase shifted RF signals to produce N amplified, phase shifted RF signals. The power combiner network combines the N amplified, phase shifted RF signals to produce N output RF signals. Each of the radiation devices receives one of the N output RF signals, and produces a plasma discharge when a power level of the output RF signal is sufficiently high.

Abstract: When engine rotation speed is increasing in a compression stroke injection mode, a control device determines that a crank angle at injection end timing of an injector deviates toward a delayed crank angle side and performs additional ignition at timing when (or immediately before or after) a crank angle at actual injection end timing of the injector of a present injection cylinder is reached. Thus, even when the crank angle at the injection end timing deviates toward the delayed crank angle side with respect to preset original ignition timing, a combustion state can be stabilized by performing the additional ignition at timing, at which a suitable stratified mixture gas is formed in a cylinder, through the execution of the additional ignition at the timing substantially the same as the actual injection end timing.
