PURPOSE:To make exhaust gas emission control performable so favorably even at the time of engine cold, by performing a secondary air supply in a port air injection system at the time of engine cold, while constituting this secondary air to be supplied in a manifold air injection system after...
SECONDARY AIR SUPPLY SYSTEM IN INTERNAL COMBUSTION ENGINE PURPOSE:The operation of the changeover control mechanism to control the working fluid pressure to a diaphragm unit to open and shut off the secondary air control valve in proportion to the exhaust atmosphere in the exhaust pipe enables ......
PURPOSE:To provide a secondary air supply system, which can effectively purify the non-combustion component in the exhaust gas with the rate of supply of the secondary air made proportional to the rate of withdrawal of air by making the pressure difference between the upstream and downstream sides...

Calabar, Nigeria Correspondence: Ogugua N Okonkwo, Eye Foundation Retina Institute, Lagos, Nigeria, Tel +234 803 502 7308, Email o_okonkwo@yahoo.com Purpose: To report incidence, clinical presentation, and treatment outcome of full-thickness macular hole (FTMHs) diagnosed post pars plana vitrectom...
For this purpose, so much of an aqueous solution of DHBQ in distilled water was applied to the pulp that a DHBQ content of 3 ppm or 10 ppm, respectively, was reached after drying. Then the pulp was kneaded for a few minutes. The DHBQ is firmly adsorbed to the cellulose under these...
A secondary air system for an internal combustion engine (32), including at least one line (14) through which air is blown into the exhaust pipe of the engine, a pump (26) and a drive (27) for the pum
A secondary air supplier supplies secondary air to an exhaust passage, when an engine is in a predetermined condition. An oxygen sensor detects the air-fuel ratio (A/F) in the exhaust gas. The air-fue
In addition, the secondary containment system should allow for complete inspection of the primary pipe fittings during an air pressure soap test, before the secondary pipe system is completed. Further, the secondary containment system should be compatible with the products to be stored. In addition,...
This invention relates generally to a fuel and air injection apparatus and method of operation for use in a gas turbine combustor for power generation and more specifically to a device that reduces the emissions of nitrogen oxide (NOx) and other pollutants by injecting gaseous fuel into a combust...
