Title:
SIGNAL PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/105571
Kind Code:
A3
Abstract:
The present invention uses an engine control device (13), which cannot output a control signal to an electromagnetic wave radiation device (30), to radiate electromagnetic waves from the electromagnetic wave radiation device (30) to a combustion chamber (10) in an engine (20) at an appropriate timing. A signal processing device (40) is connected to an engine control device (13) which outputs, to an ignition device (12) in the engine (20), an ignition signal for instructing the execution of an ignition operation for igniting the air-fuel mixture in the combustion chamber (10) of the engine (20). The signal processing device (40) receives the ignition signal and then outputs, to the electromagnetic wave radiation device (30), an electromagnetic wave drive signal specifying the radiation period of the electromagnetic waves on the basis of the ignition signal, so that the ignition operation is executed during the radiation period in which the electromagnetic wave radiation device (30) attached to the engine (20) radiates electromagnetic waves to the combustion chamber (10).
