Abstract
Abstract A mixer (10) for entraining gaseous fuel into an airstream for induction into an internal combustion engine (12) having a turbocharger (13). The mixer has a housing (16) mounted to a conduit (14) between the turbocharger and the engine. The mixer also has a control ring (32) mounted to the housing that has an annular array of holes (39) through which gaseous fuel, from a supply of gaseous fuel coupled to the housing, is introduced into the airstream passing through the mixer and into the engine.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
141 words
Apparatus for entraining gaseous fuel into an airstream for introduction into the intake port of an internal combustion engine, and with the apparatus comprising a housing having a tubular wall with a tubular plenum therein bounding an airstream channel, said tubular wall having an annular array of orifices in fluid communication with said airstream channel and said plenum and a removable, annular, hollow ring through which said orifices extend, said housing also having a channel block having a gaseous fuel channel therethrough in fluid communication with said plenum; fuel control means mounted within said gaseous fuel channel for controlling the flow of gaseous fuel therethrough; and means for mounting said housing to the intake port, whereby gaseous fuel introduced into the plenum is passed through the annular array of orifices into an airstream passing through the airstream channel and entrained therein.
Claim 2
Dependent Claim
141 words
Apparatus for entraining gaseous fuel into an airstream for introduction into the intake port of an internal combustion engine, and with the apparatus comprising a housing having a tubular wall with a tubular plenum therein bounding an airstream channel, said tubular wall having an annular array of orifices in fluid communication with said airstream channel and said plenum and a removable, annular, hollow ring through which said orifices extend, said housing also having a channel block having a gaseous fuel channel therethrough in fluid communication with said plenum; fuel control means mounted within said gaseous fuel channel for controlling the flow of gaseous fuel therethrough; and means for mounting said housing to the intake port, whereby gaseous fuel introduced into the plenum is passed through the annular array of orifices into an airstream passing through the airstream channel and entrained therein.
Claim 3
Dependent Claim
140 words
Apparatus for entraining gaseous fuel into an airstream for introduction into the intake port of an internal combustion engine, and with the apparatus comprising a housing having a tubular wall with a tubular plenum therein bounding an airstream channel, said tubular wall having an annular array of orifices in fluid communication with said airstream channel and said plenum, said housing also having a channel block having a plurality of gaseous fuel channels therethrough in fluid communication with and between a supply of gaseous fuel and said plenum; fuel control means mounted within said gaseous fuel channel for controlling the flow of gaseous fuel therethrough; and means for mounting said housing to the intake port, whereby gaseous fuel introduced into the plenum is passed through the annular array of orifices into an airstream passing through the airstream channel and entrained therein.
Claim 4
Dependent Claim
140 words
Apparatus for entraining gaseous fuel into an airstream for introduction into the intake port of an internal combustion engine, and with the apparatus comprising a housing having a tubular wall with a tubular plenum therein bounding an airstream channel, said tubular wall having an annular array of orifices in fluid communication with said airstream channel and said plenum, said housing also having a channel block having a plurality of gaseous fuel channels therethrough in fluid communication with and between a supply of gaseous fuel and said plenum; fuel control means mounted within said gaseous fuel channel for controlling the flow of gaseous fuel therethrough; and means for mounting said housing to the intake port, whereby gaseous fuel introduced into the plenum is passed through the annular array of orifices into an airstream passing through the airstream channel and entrained therein.
Claim 5
Dependent Claim
146 words
A fuel control system for use in entraining gaseous fuel into an internal combustion engine for ignition comprising, in combination, an air-to-air cooled turbocharger; conduit means for conveying an airstream from said turbocharger into the internal combustion engine; an air/fuel entraining means coupled to said conduit means for entraining gaseous fuel with the airstream conveyed through said conduit means; a high pressure gaseous fuel cell; gaseous fuel conduit means for conveying gaseous fuel from said fuel cell to said entraining means; and fuel metering means for metering the flow of gaseous fuel through said gaseous fuel conduit means; whereby gaseous fuel may be entrained into the turbocharged airstream passing into the engine by introducing it at a pressure greater than that of the turbocharged airstream and at a position along the conduit means which minimizes the danger resulting from the possible rupture of the conduit means.
Claim 6
Dependent Claim
146 words
A fuel control system for use in entraining gaseous fuel into an internal combustion engine for ignition comprising, in combination, an air-to-air cooled turbocharger; conduit means for conveying an airstream from said turbocharger into the internal combustion engine; an air/fuel entraining means coupled to said conduit means for entraining gaseous fuel with the airstream conveyed through said conduit means; a high pressure gaseous fuel cell; gaseous fuel conduit means for conveying gaseous fuel from said fuel cell to said entraining means; and fuel metering means for metering the flow of gaseous fuel through said gaseous fuel conduit means; whereby gaseous fuel may be entrained into the turbocharged airstream passing into the engine by introducing it at a pressure greater than that of the turbocharged airstream and at a position along the conduit means which minimizes the danger resulting from the possible rupture of the conduit means.
Claim 7
Dependent Claim
23 words
The fuel control system of claim 3 wherein said fuel metering means meters the flow of gaseous fuel closely adjacent said mixing means.
Claim 8
Dependent Claim
49 words
The fuel control system of claim 3 wherein said mixing means comprises a housing having a channel therethrough, an annular plenum and an annular array of orifices in fluid communication with said channel and said plenum through which the gaseous fuel is injected into air passing through said channel.
