Abstract
Abstract A modified two-stroke or four-stroke internal combustion engine comprises means and a method for increasing the power output of an internal combustion engine by providing a non-combustible fluid to the engine. The engine transfers thermal energy of combustion to the non-combustible fluid, thereby causing expansion of the fluid, and includes means for converting expansion of the fluid to mechanical power.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
156 words
An internal combustion engine operating on a two-stroke cycle or a four-stroke cycly having a power stroke, comprising: means for providing a combustible fuel to said engine at the start of the power stroke; first means for igniting said fuel during the power stroke to produce mechanical power; means for providing a non-combustible fluid to said engine during the power stroke after said first means has ignited said fuel and after said ignited fuel has substantially reached the point of flame-out in order to transfer thermal energy from said ignited fuel to said non-combustible fluid, thereby causing expansion of said fluid during the power stroke; and means for converting expansion of said fluid to mechanical power during the power stroke, wherein said non-combustible fluid comprises a fluid having good temperature expansion characteristics and which condenses at a substantially faster rate than burned combustible fuel exhausted from the engine, and wherein said non-combustible liquid comprises a halogen.
