Abstract: A nozzle for mixing and delivering two or more components and method of use thereof. One variation provides a nozzle that injects a first component, such as fuel, into a flow plume for a second component, such as nitrous oxide, for use with combustion engines. The nozzle receives two or more separate flows of components (e.g., gases and/or liquids), one of which is pressurized so as to be outputtable from the nozzle as a plume. The plume is directed so as to encompass an output extension for the other component near the plume edge, thereby enhancing mixture of the components. In addition, the plume produces a low pressure draw of the second component from the output extension, the low pressure draw varying with plume velocity, in turn varying with delivery pressure of the first component. The plume flow of the second component also atomizes the first component, further enhancing mixing.

Abstract: A modular intake manifold for an internal combustion engine that has a lower base member, a center runner section, and an upper shell. The lower base member has a series of outlets and witness marks formed within the outlets and attaches to an engine between right and left cylinder heads. The center runner section is situated within the base member for channeling incoming air into the series of outlets in the lower base member. The upper shell attaches to the lower base member, includes a throttle body mounting boss, seals and isolates the individual runner sections of the center runner section, and encloses the intake manifold. The intake manifold may be assembled and disassembled freely. Once disassembled, a different upper shell or center runner section, each having differing features from the components previously removed, may be reattached to the lower base member to alter the engine performance in some way.

Abstract: An air amplifier and method and system for using a source of compressed oxygen enhancer, such as nitrous oxide, to increase air flow into an internal combustion engine, providing increased power gain for the engine over the power gain provided by the addition of the oxygen enhancer alone. A source of compressed gas is fed into an air amplifier positioned in the air intake tube for the engine, such as a hose or other conduit which leads to, for example, the throttle body for the fuel injector system. The compressed gas, which includes or is made up of an oxygen enhancer, such as nitrous oxide, is fed into the air amplifier near the inner edge of the air intake tube, producing a Coanda effect, such that air intake into the engine is greatly increased. The device is useful in conjunction with oxygen enhancer systems, such as nitrous oxide kits for feeding nitrous oxide into the throttle body for fuel injected internal combustion engines.

In one application, the triggering occurs via an engine electrical output, such as a throttle position sensor (TPS) voltage. The trigger, which includes, for example, an operational amplifier circuit, logic gates, or a series of transistors (e.g.

The pressure from the manifold is transferred by a connection to the fuel pressure regulator of the vehicle, so that fuel delivery varies proportionally to the pressure of the nitrous oxide source.

Abstract: A double U shaped exhaust pipe having varying internal pipe diameters for increasing horsepower, designed within internal combustion engine vehicle racing or other rules that limit such features as overall size. A first stage portion of the exhaust pipe produces a first periodic flow of exhaust, with a vacuum pulse created where the pipe internal diameter increases upon the exhaust reaching a second stage portion. A third stage portion of the exhaust pipe produces a third stage periodic flow of exhaust upon the exhaust reaching an increased pipe internal diameter at a fourth stage portion. These periodic pulsed flows are matched to the opening of the intake and exhaust valves of the engine for a selected engine speed range. The matching of a vacuum pulse to the opening exhaust valve improves engine performance by drawing exhaust gases from the engine.
