Document Type and Number:
Japanese Patent JP6399474
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a flow control device in a combustion chamber, which can reduce a cooling loss caused by a squish flow or a reverse squish flow in an engine with a squish area formed between the peripheral part of a piston top surface and the ceiling surface of the combustion chamber.SOLUTION: A flow control device in a combustion chamber has a plasma actuator (28) arranged in the combustion chamber (16). The plasma actuator comprises a dielectric body (38) arranged along the side wall surface (34a) of a cavity (34), exposure electrodes (40) arranged on the combustion chamber side of the dielectric body, and embedded electrodes (42) arranged on the opposite side of the exposure electrodes across the dielectric body. The embedded electrodes are arranged on a side closer to the bottom surface (34b) of the cavity than the exposure electrodes.SELECTED DRAWING: Figure 5
