turbine blades this invention comprises a dual function conduit means connecting internal combustion engine exhaust to a relatively low speed turbine wherein the conduit means also induces an appreciable flow of outside air to mix with the exhaust gases to effectively lower the temperature of the gases imposed on the turbine but without lowering the total energy of the gases application_number US 92088692 A description referring to the drawings fig1 shows a first embodiment of the invention 1 in use with an internal combustion engine 10 as can be seen in fig1 an engine 10 a coupling and control unit 12 and a generator 14 are connected in a manner well known in the art with each being mounted on a base 16 the engine 10 has an exhaust pipe 18 shown in dotted lines part of which is enclosed by a tapered cylindrical cover or conduit 20 the larger diameter portion of the cover 20 facing the engine 10 is spaced from the engine 10 to permit outside air to flow into the cover 20 and around pipe 18 as shown in fig1 a and 1b cover 20 is suitably connected to the engine 10 for support by means such as bracket 19 cover 20 tapers down to the diameter of tube 22 and is attached thereto slightly upstream of a perforated portion of pipe 18 tube 22 is in fluid communication with conical member 24 which is in turn connected to and in fluid communication with turbine 26 note that pipe 18 extends into tube 22 as shown in fig1 and 3 exhaust pipe 18.
