An internal combustion engine system that is selectively powered by an enhanced air/fuel mixture. The supply of fuel to the cylinders of an internal combustion engine is increased in response to the addition of a supplemental oxidizing agent into an air/fuel mixture. The additional fuel may be added by increasing the duty cycle of fuel injectors mounted proximate the individual cylinders. In addition, the ignition timing is adjusted in accordance with the change in the density of the fuel air mi...

A nitrous oxide and fuel injector assembly is mounted to an air supply conduit of an internal combustion engine. A support platform (24), (66) is placed inside the air supply conduit in abutment with the external wall of the air supply conduit, with connector conduits (26), (68) extending from the support platform through openings in the air supply conduit, so the connector conduits protrude outwardly from the air supply conduit. Fasteners, such as internally threaded nuts (34), are threaded ont...

A dual display temperature/pressure gauge (10) for a container (8) of compressed liquefied gas includes a planar strip of material having a display side (12) which is visible when the strip is placed in contact with a container (8) of compressed liquefied gas; a temperature display region (14) on the display side (12) which includes a first set of numerals representing a range of measured temperature readings; a pressure display region (16) on the display side (12) which includes a second set of...

The present invention is a system and method of reducing nitrogen oxides in coal combustion exhaust gases and preventing fire and explosion in pulverized coal systems. The present invention first cools the flue gas exiting a boiler of the pulverized coal system with an air preheater. The present invention removes any particles such as fly ash from the cooled flue gas with an electro-static precipitor or a bag house and recirculates the flue gas. The temperature of the recirculated flue gas is ad...

A 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 vapor 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.2O content, such as gases resulting from plants for the manufacture of nitric acid, and of gases with a high N.sub.2O content, which are emitted during o...

This invention is a nitrous oxide delivery system to improve engine power in which the nitrous oxide leaves its storage bottle as a vapor rather than conventional liquid delivery systems in which it leaves as a liquid. This system can therefore use a relatively simple pressure regulator and fixed orifice to maintain an essentially constant nitrous oxide mass flow rate over a wide range of storage bottle pressure. The nitrous oxide which enters the engine does not contain any ice crystals and wil...

This invention relates generally to a method for producing nitrous oxide, and more specifically, to a method for producing nitrous oxide by reacting ammonia with at least one molten nitrate salt.

The invention concerns a method for purifying flue gases before they are released into the atmosphere of their nitrogen oxides N.sub.2 O and NO.sub.x by reaction with ammonia by causing them to circulate at temperatures between 200 and 600.degree. C. on a catalyst based on beta-zeolite loaded with iron. The invention is particularly useful for treating tail gases from factories producing nitric acid.

A process is disclosed for use in the manufacture of multilayer thin film integrated circuits for selective removal of specific layers, and a composition of matter useful in the process for selective etching of polysilicon and silicon nitrides during the manufacture of thin film integrated circuits. A multi-layer thin film integrated circuit is exposed to a plasma formed from a gaseous mixture of nitrous oxide and a fluoro compound. The nitrous oxide preferably comprises between 2.5% and 9.0% of...

A supplemental nitrous oxide and fuel injection system for use with an internal combustion engine, which includes the unique properties of variable flow-rate control of the supplemental injection system and direct cylinder injection methods. Where an engine is normally controlled by the driver with the (0-100%) throttle control of the existing air/fuel system, this supplemental nitrous oxide and fuel injection system is linked to the existing throttle control and controlled in the same manner. I...
