A low power or current draw adjustable trigger switch and method and system for using the adjustable trigger switch in conjunction with a triggered accessory for an internal combustion engine, such as a feed from a source of compressed oxygen enhancer, such as nitrous oxide. The adjustable trigger switch, in operation in conjunction with the triggered accessory, allows selective activation of the accessory to, for example, improve engine performance. In one application, the triggering occurs via...

A tunable nitrous plate assembly for fuel injected 5.0 liter V8 engines contains a metal plate (1) that is sandwiched between the upper and lower manifold members of the engine air intake manifold. The plate contains multiple ports (17) mate with the ports in the lower manifold member and, thereby, lead to individual intake runners of the engine cylinders. Each port includes a nitrous oxide spray conduit (21) overlying a fuel spray conduit (23) with both conduits extending across the port transv...

A process and catalyst for reducing the nitrous oxide content in gas, which operates at relatively low temperatures, the activity of which is relatively insensitive to the presence of water vapour and which is highly resistant to hydrothermal degradation, is prepared from ferrierite exchanged with iron. Application to the treatment of gases with a low N.sub.2 O content, such as gases resulting from plants for the manufacture of nitric acid, and of gases with a high N.sub.2 O content, which are e...

A self-contained system which converts nitrous oxide to a breathable gas mixture of nitrogen and oxygen. In the preferred embodiment of the present invention, a portable system is disclosed wherein liquefied nitrous oxide is converted to a breathable gas mixture of nitrogen and oxygen. The decomposition occurs over a catalyst bed which is all contained in a small reactor. The invention is useful for underwater, fire fighting and outer space applications.

A nitrous oxide or fuel control valve has flow control of nitrous oxide from a fluid-delivery aperture (7) or flow control of fuel from a fluid-delivery aperture (8) into a injection nozzle (22) of an intake manifold of an engine by actuation of an adjuster coupler nut (11) with an actuation piston (14) that is actuated with gas pressure from an actuation-pressure source (43) with an actuation on/off valve(25). It can be structured for low-weight, short-term needs for racing and other sports use...

To estimate nitric acid ions and nitrous acid ions in a sample solution, a method is proposed which comprises the steps of (a) feeding both the sample solution and a reducing agent to an acidic solution which is flowing in a thin pipe; (b) positively mixing the sample solution and the reducing agent and thus reacting the same in a given portion of the pipe; (c) leading the reacted solution to a gas/liquid separator thereby to separate a gaseous phase from the reacted solution; and (d) estimating...

The present invention relates to a nitrous oxide injection device and system, and a method of installation of the device and system, and, in particular, to a self-contained, easy to install nitrous oxide device that provides fuel delivery that varies with nitrous oxide tank pressure by way of a manifold that is pressurized by a bleed orifice from the nitrous oxide source. The pressure from the manifold is transferred by a connection to the fuel pressure regulator of the vehicle, so that fuel del...

Methods and apparatus for monitoring the reaction between a metal, and/or metal oxide, reactive with nitrous oxide wherein a mixture of nitrous oxide and a diluent is passed through a bed of a material containing the metal, or metal oxide, and the time to a marked change in the exit gas composition is determined. The procedure is of particular utility for metal surface area determination.

A redox electrode for determining nitrous acid and nitrosyl compounds in aqueous, acidic solution consists of a metallic conductor on which an n-conducting metal oxide surface is present.

Anoxidizer and fuel plate is disclosed which discharges nitrous oxide and fuel into an intake manifold.The plated between a carburetor and an intake manifold and it provides a construction which slow the flow of the nitrous oxide so that the nitrous oxide introduced into the airstream is substantially uniformly distributed.
