The basic design and method of reciprocating piston in cylinder ICE hasn’t changed much. Why any of the numerous patents granted for expansion of exhaust gases in additional cylinder(s) have been implemented? I have applied for one modification/invention where exhaust gases are fully decompressed in additional cylinder(s) and is termed as power stroke there. Cross sectional cumulative area of additional cylinder(s) pistons is such that cumulative FORCE acting on these piston(s) / ConRod(s) at TDC while receiving exhaust gas and peak FORCE on IC Engine Piston/ConRod in its power strokes are matched (inter alia these are integral multiples of peak force in combustion stroke of ICE cylinder). Movement of pistons in those two types of cylinders in their respective power strokes with equal initial force and with equal strokes (stroke lengths) ensures equal amount of mechanical work/power imparted. Thus values of additional power of THE PATENTED ENGINE per exhaust stroke compared to power of conventional I C Engines as percentage are 100% 200% 300% etc.
There are already some on the taste beds in R&D of established corporate manufacturers. The power derived in additional cylinder is a fraction of power stroke of ICE e.g. 40% additional efficiency with say twice the bore of ICE cylinder. Connection of such a piston on crankshaft with unbalanced power strokes and a single outsized additional cylinder makes such inventions unattractive. THE ENGINE of MY PATENT overcomes those drawbacks. Please see updates for more explanation.
I C Engine pistons individually derive same power and power density in power strokes in conventional four strokes four cylinder ICE (and more pistons in case of multi cylinder ICE). Also at a given moment the speed of four pistons (during power stroke) is same in their movement from TDC to BDC. This is in spite of other three pistons simultaneously deriving debilitating negative power. This is due to fact that there is only one type of power at a given moment. In THE ENGINE of MY INVENTION there are simultaneous unbalanced power strokes on different pistons that results in uneven speeds of pistons at a given moment. This can be the foremost reason that such patents haven’t been implemented. See more updates to my project.
