Abstract: An engine includes an engine casing and a first piston configured to reciprocate relative to the engine casing. The first piston has a wall that defines a substantially cylindrical chamber. One or more second pistons are configured to reciprocate inside the substantially cylindrical chamber. A combustion chamber intake port and a combustion chamber exhaust port extend through the wall. A shutter is outside the wall and is movable between a first position substantially blocking fluid flow through the combustion chamber exhaust port but not blocking fluid flow through the combustion chamber intake port and a second position substantially blocking fluid flow through the combustion chamber intake port but not blocking flow through the combustion chamber exhaust port. An actuator causes the shutter to move between the first position and the second position in response to the first piston reciprocating relative to the engine casing.

Abstract: A plasma actuator (1) includes four electrodes (11) and three dielectrics (10) and is disposed on the side of an object surface (B). When a high voltage is applied to the electrodes (11), a plasma (15) is generated at an end (10a) of each dielectric (10) exposed so as to be accessible to a gas. In the plasma actuator (1), the electrodes (11) and dielectrics (10) are alternately stacked one on another. The plasma actuator (1) includes a stepped exposed portion (X). The plasma actuator (1) in which the electrodes (11) and dielectrics (10) are arranged such that the ends (10a) of the dielectrics (10) are exposed in the normal line direction of the object surface (B) in the stacked order in the stepped exposed portion (X) can suppress the flow of the generated plasma even when the plasma actuator is exposed to a high-speed airflow under high pressure. This stabilizes the plasma.

Abstract: A four-cycle internal combustion engine with a valve system having improved durability in the case of high revolution speed. The engine includes a cylinder head having a port, and a valve having a stem part continuous with a fillet part for opening or closing the port. A valve spring including inner and outer springs urges the valve in a direction to close the port. A valve guide holds the stem part slidably. A tubular spring guide supports an outer periphery part of an outer spring to prevent lateral deformation of the spring. A top end of the spring guide is positioned above a top end of a valve guide.
