ABSTRACT:
A compact expansion chamber for increasing the power of small internal combustion engines, particularly outboard engines for model boats. Its very compact, generally S-shaped configuration allows its center of gravity to be quite close to the engine to which it is attached, thus providing a very short moment arm. This allows model boats upon which it is installed to remain well balanced and level so that they are more maneuverable and quicker to respond to the radio control signals. The expansion chamber (10) comprises: a straight inlet pipe (12) having a flange (22), a diverging section (14) having a 150 degree bend, a straight tubular section (16), a converging section (18) having a 90 degree bend in the direction opposite to the bend in the diverging section, and an outlet pipe (20). A pressure tap fitting (24) connects to the fuel tank pressure line so as to improve fuel flow to the engine. A boss (26) receives a mounting screw and allows the expansion chamber (10) to be attached by a metal strap to the engine.
