This invention relates to a heat engine which I claim functions more efficiently thermally than conventional heat engines operating currently,especially the 4 stroke "OTTO" cycle heat engines that operate well below CARNOT's max efficiency level.It is necessary to highlight certain events of a typical 4 stroke "OTTO" cycle heat engine, in order to indicate how my invention improves overall efficiency. As an example using an engine having a compression ratio which multiplys it's original charge to 200psi, at which moment if at an optimum temperature of 500°Kelvin, containing an optimum volume of gaseous fuel, activated to erupt and form a combustion reaction with an increase of mole products, along with the resulting thermal energy, will increase the pressure by a factor that is determined from the increased rise of sink temperature e.g:- if from 310°K to a compressed state at 500°K, now further increased by combustion to an estimated (scource) Temperature of 1200°K then our original pressure increased by the (1200/310)factor of (3.87) along with reactionary pressure should produce aprox' 800 pounds per square inch, acting upon a 10 sq" piston crown will apply 8000 pounds force, which in turn applied through the connecting rod and crankshaft's angle of obliquity, should generate torque accordingly. Such torque is minimal initially and maximises at an angle within the first 90 degrees of rotation at a point determined by the ratio lenghts of the connecting rod and the crank radius, however before reaching this position, heat energy is lost through the cylinder surrounds, and pressure reduces as the volume increases, In fact only around 150°of ERRATIC power is generated during it's 720° "OTTO" cycle, complicated by the exhaust valve commencing to open around 4800 against high internal pressure, thereby allowing a tremendous amount of potential heat energy to escape without doing any useful work. Such characteristics along with the fact these "OTTO"cycle heat engines are the subject of much concern in the way they pollute our environment, led me to rearrange conventional heat engine components much more advantageously to warrant that greator than 60% "CARNOT" Max thermal efficiency is attainable,now to be described in the following specification:-
