     INTRODUCTION 
       [0002]    This inventor received a US Patent in 2003, U.S. Pat. No. 6,546,901 on a new type of two cycle internal combustion engine. Since then I have filed many US Patent Applications on various embodiments of that invention. Recently, during the past years I have filed versions of the invention that showed how to increase the output and efficiency of the engine by using the exhaust gases of the engine to make steam that is used as a working fluid to make power in addition to using the combustion gases produced by the two cycle engine that force a piston to move between TDC and BDC to drive a crankshaft, piston and rod assembly to produce engine horsepower. 
         [0003]    The instant invention focuses on improving the heat transfer between the engine exhaust gas of the two cycle internal combustion engine and the water that the engine exhaust gases heats into steam by forcing the exhaust gases through a heat exchanger of a unique design.

The engine housing contains housing spaces  32 , including an air intake port  34 , formed in the top surface  36 , of the engine housing that encloses a partial cylinder  38 , that contains a positive displacement gear compressor gear shaft  40 , and a partial cylinder  42 , that contains a positive displacement gear shaft  44 , that the air intake connects to. The partial cylinders connect to an air outlet port  46  that encloses a fuel injector hole  48  to contain a fuel injector  50  and a spark ignition hole  52  to contain a spark plug  54 . The air outlet port connects to a rectangular opening  56 , formed in the engine housing that contains a reciprocating part  58 . The reciprocating part is rotationally connected to a crankshaft rod bearing  60  formed on a crankshaft  62  that is located inside a crankcase  64  formed inside the engine housing that encloses a crankshaft output shaft hole  66 , to enclose crankshaft output shaft  68  located in housing part  24  and another crankshaft output shaft hole  70 , to enclose crankshaft output shaft  72 , located in housing part  26 . 
         [0007]    A second engine house  74  of identical construction is located in opposed form but does not contain either a spark plug or a fuel injector or the holes used for receiving them as is described for engine housing  22 . The second engine housing is used as a steam engine and it&#39;s crankshaft output shaft  76  is connected to an output gear  78  that meshes with a idler gear  80  rotationally attached to the engine housing that meshes with a compound drive gear  82  attached to the input shaft  84  of a positive displacement gear shaft  86  of the second engine housing and that first drive gear meshes with a second compound drive gear  88  attached to an output shaft  90  of the positive displacement gear shaft  40  of the first engine housing. The second drive gear is meshed with a second idler gear  92  rotationally attached to the first engine housing and meshes with a second output gear  94  attached to the first crankshaft output shaft  68  for a power transfer between crankshaft output shaft  68  of the first engine housing and the crankshaft output shaft  76  of the second engine housing so that the power generated by the two cycle internal combustion engine is combined with the power output of the two cycle steam engine of the second engine housing. 
         [0008]    Rectangular opening  56  encloses an exhaust port  96  in a side wall  98  located near the compressor end of rectangular opening  56 .

         [0010]    A steam engine intake valve  142  is located by the engine housing steam intake port  144  that is connected to the steam exit passage  146  in the heat exchanger to control the flow of steam into the positive displacement gear compressor to compress the steam into the steam engine housing during the engine power stroke to force the reciprocating part  148  from the TDC position to the BDC position of crankshaft rotation to increase the power and efficiency of the engine. 
         [0011]    A turbocharger  150  exhaust inlet port  152  is connected to the exhaust outlet of the heat exchanger. The turbocharger compressor air outlet  154  is connected to the compressor inlet  156  of the engine housing  22  air intake  34  to turbocharger the air flowing into the Two Cycle Internal Combustion Engine positive displacement gear compressor  158  to form a compound supercharger  160  for the Two Cycle Internal Combustion Engine.

       Operation of the Engine 
       [0015]    When the engine is started by the engine operator or engine management system the crankshaft of the engine rotates forcing the reciprocating means within the engine and the compressors to compress air into the engine between the reciprocating part and the compressor where the hot air ignites fuel sprayed into the compressed air. The burning fuel mixture forces the reciprocating means to the bottom dead center position at which time the cam lobe on the compressor shaft forces open the engine exhaust valve. During the movement of the reciprocating parts of both engines from BDC to TCD exhaust gases from the two cycle internal combustion engine flow through the exhaust passage into the turbocharger turbine spinning it forcing the turbocharger radial compressor to force more air into the two cycle engine positive displacement gear compressor. As this is occurring the hot exhaust gases flowing through the exhaust passage heat the fins inside and outside on the heat exchanger. The water sprayer sprays water on the heat exchanger fins where steam is created by the evaporation of the water that has contacted the heat exchanger fins. The steam gases fill up the heat exchanger interior and rise the pressure level inside it. The steam engine steam intake passage valve opens at TDC position of steam engine crankshaft rotation and steam enters the steam compressor intake port where it is compressed into the engine housing to force the reciprocating means down from the TDC to the BDC position rotating that crankshaft another 180 degrees to increase engine power and efficiency. 
         [0016]    The rotation of the Two Cycle Internal Combustion Engine crankshaft drives the gear train connected to the crankshaft output shaft that drives the idler gear to drive the compressor gear shafts and the second idler gear that drives the steam engine crankshaft of the second engine housing to force the second crankshaft to also move the second reciprocating means from the top dead center position to the bottom dead center position and back up to the top dead center position. When the reciprocating means of the second engine housing is at TDC the cam lobe on the second compressor makes the pushrod to push the intake valve open and let steam from the heat exchanger into the steam engine compressor to force the second reciprocating means from the TDC position to the BDC position. Before the intake valve opens the exhaust valve closes and air inside the Two Cycle Internal Combustion Engine is compressed again between the reciprocation means and the compressor in the engine housing  22 . At TDC more fuel is injected into the compressed air and ignition again occurs in the two cycle internal combustion engine forcing the reciprocating part away from TDC position and simultaneously steam pressure enters the steam engine housing and forces the steam engine reciprocating part away from the TDC position to the BDC position to increase engine power and efficiency.
