Abstract: In the preferred embodiments an air flow diverting blade is integral to a base that doubles as a collar designed to co-axially attach to the nozzle tip end of a typical port fuel injector for internal combustion engines. Upon simple manual manipulation of the set rotational angle of the typically externally exposed portion of the port fuel injector along its longitudinal axis, as typical modern port injection systems allow after installation, the angle of the intra-port flow diverting blade can be selectively varied to either straighten existing swirl and increase top end flow, or, introduce lateral directional swirl to whatever angle and intensity in either direction is desired. The functional use of a typical port fuel injector is thereby elevated to a multifunction of tunable fuel and air flow control at the point of induction into a combustion chamber without any modification to existing engine designs or their engine management control systems employed therefore.

Abstract: A new syringe design is provided with a safety feature that prevents inadvertent or otherwise unintended release of any contents within the syringe. This safety feature is accomplished by way of an automatic (passive) plunger locking mechanism. The new syringe design also providing for automatic (passive) disengagement of the automatic plunger locking mechanism so as to not inhibit the operating use and function of a syringe.

Abstract: A syringe designed with a passive safety locking means to effectively and reliably disallow unintentional displacement of the plunger toward the distal end if the syringe. The safety locking means is designed to affect reliable automatic release on at least two (2) points of engagement of the syringe for its intended use namely the controlled dispensement of generally viscous substances therein.

Abstract: A next generation hybrid valve concept for enhanced induction cycle function for internal combustion engines. Said hybrid valve effectively combining automatic pressure activated check valve function with traditional poppet valve function to create an effective low cost self regulating variable valve timing (VVT) system. Said hybrid valve consisting of a free floating annular ring seal which is affixed concentrically around a modified poppet valve seat or within an engine head seat insert configured with releasably sealable jet flow passage ways. The concept can provide an effective range of late opening and early closing times to control reversion as well as a very broad range of early opening and late closing times.

Abstract: A variable displacement valve seat that consists of an annular ring which is affixed concentrically around a standard valve seat. The annular ring is affixed loosely to allow linear coaxial movement along the valve seat center-axis line. The movement is restricted to a small fraction of the valves actual displacement, approximately 12% or less, in the preferred embodiment. The annular ring is affixed to the valve seat insert installed in the cylinder head when used on the exhaust side. The annular ring is affixed to the head portion of the poppet valve itself when used on the intake side. The concept can provide an effective range of early closing times for the valves to control reversion. In addition, the actuation of the moveable seat is variable and automatic, and controlled by cycle exchange functions.
