Piston at T.D.C., end of compression stroke, with fuel/air mixture properly combined and highly compressed, ready for detonation where explosive force is thrust upon the stationary piston (stationary or motionless since it is neither moving upward or downward until crankpin advances to approximately 25° plus after T.D.C. or 0°).
T.D.C. being the important or salient moment where maximum binding, or seizure moment occurs on three vertically inline journals A, B, and C, inducing enormous temporary friction losses and intense heat production, which tells us that another strategy is necessary. The only pragmatic solution to this dilemma would seem to be a suitable offline connecting linkage between piston wristpin journal A and crankpin journal B. It must be simple and structurally durable, easy to construct and require no additional scheduled servicing. The most expedient and practical application would be a trigonal linkage system (see Graphic
Be it known that I, Michael D. Gilmartin, resident of Broadmoor Village, San Mateo County, Calif. in the United States of America invented by careful study and a half-century of hands-on experience a new and unique component to the internal combustion engine with the determinative purpose of improving the efficiency factor rating of said internal combustion engine—the type used for transporting passengers, freight, liquid, etc. on land, water, air, or stationary service.
It is my belief that there is very little wrong with the fuel being used for the past thirty years: gasoline, petroleum spirit, the usual hydro-carbon fuel. Carbon monoxide, oxides of nitrogen, etc. should be reduced by fitting the trigonal linkage system and should be progressing towards a more inert state. This does not imply that the overall exhaust quantity will be devoid of inherent toxins but a very subdued noxious emission will be evident since also projected fuel intake will be reduced by at least 50%. (Refer to Fuels pg. 9 in this disclosure)
Heat and friction losses are not solely produced by oil pressurized journals, well-designed pistons, valve mechanisms, etc. Certainly these cause low grade friction, but not to a pitch where it absorbs 50% of power output. If that were so, an engine running at 18,000 RPM, as Formula One GPV8 High Performance engines do, would not have gained power output but would proportionally diminish energy production to zero output. So, it becomes obvious that power should be applied within a degree range where it will effect the greatest energetic force on the crankshaft and flywheel assembly and not where the piston has stopped motionless, (must stop to regain its rectilinear or reciprocal motion) on the third or power stroke the precise moment when the combustion is ignited. The explosive force is thrust upon the stationary piston, with crankpin and connecting rod in vertical position; motion is impossible. It is only by the rotational constancy of the flywheel that it will keep turning. Meanwhile, thermodynamic pressure is captive with no place to go. A potent and highly vigorous energy source, regretfully thermodynamic pressure is a fleeting and vanishing entity. It would be difficult to emphasize the swiftness with which this precious energy source decreases or diminishes, by losses, to heating the surrounding metals, rapidly expanding combustion space by piston travel and the natural temperature recession to ambient. The result crankshaft, binding or seizure moment and seizure period that last until the crank reaches 25° clockwise after T.D.C. The task for the constructor is to retrain or harness this energy at its most efficacious moment.
I propose the application of a trigonal linkage system. A suitable apposite and effective attachment or coupling can be made by engineer or constructor's judgment.
An I.C.E. does not derive a useful power application from explosive impact, when it occurs at T.D.C., where crankpin journal is in vertical or perpendicular dimension. This impact unfortunately causes a severe seizure moment that extends, or becomes a seizure period or binding until the crankpin journal reaches a more vantage or prevalent angle which is at least 25° clockwise after T.D.C, (90° clockwise being the optimum or prevalent leverage crankpin angle). Thermodynamic pressure is the main and only energetic source to drive the crankshaft-flywheel assembly, but a very potent and vigorous one; Regretfully, this source, (thermodynamic pressure) is a fleeting and vanishing entity due to the highly polarized temperature differential between energy source and combustion chamber. It is difficult to emphasize the swiftness with which this thermodynamic pressure decreases or diminishes, by losses to heating surrounding metals, rapidly expanding combustion space, and the natural temperature recession to ambient. It is only by stabilizing constancy of the flywheel that it salvages a decimated energy. So at its highest and most efficacious moment it must be harnessed to the best of the constructor's ability. Initially, it is not a lacking or weakness in BMEP that is the problem, it is the means by which it is applied. Thermodynamic pressure is a very potent and dynamic force, but a rapidly diminishing one, if not captured and harnessed with the utmost haste.

Subject: Fuels—Energy derived from gasoline and used as I.C.E. fuel Gasoline, petrol, petroleum spirit produces thermal efficiency and volumetric quite effectively when the fuel mixture is properly mixed, compressed, and timely ignited. Professor Emeritus Mr. Joseph Pratt is one of the leading atheoretical experts on hydrocarbon. Until recently, Texas Panhandle was the leading oil supplier for lubricants, hydrocarbon fuels, etc. in the USA.
(The following chemical and scientific information by historian Mr. Joseph H. Pratt, University of Houston, Tex. Today's so-named “regular” gasoline is 8-carbon molecule octane and 7-carbon molecule heptane. Some years ago, scientists set the artificial scale, heptanes at 0 and octane at 100. So, octane at 8-carbon molecules, heptane at 7-carbon molecules, therefore regular, named 87, performs as if it were 87% octane and 13% heptanes and functions well for most low or moderate compression ratio engines. Gasoline vaporizes more easily, and will give more energy by weight or volume, than any other hydrocarbon.) The inordinate energy output of the Formula One G.P. engine further supports this claim of this fuel's potential.
In my judgment, a predominance of the ICE potential is misused or misplaced, perhaps as much as 60% (this does not mean 60% energy increase is available in addition to what already exists). If we examine the F1 V10 GP engine, we can get at least an objective assessment. Of course, there is no direct correlation or coefficient between EFR and PFR. The requirements are very different and the component and ancillary applications are dissimilar (this is not to say that a more efficient engine will not better respond to high performance application).
The now FIA abrogated F1-V10 Engine is something of a revelation. An F1 3-liter V10, engine naturally aspirated, on commercially available fuel at 15 to 18 thousand RPM will generate approximately 900 brake horsepower or 300 brake horsepower per liter of engine cubic capacity. (A former standard for performance from the naturally aspirated engine was 100 BHP per liter of engine cubic capacity.) These claims are made by people within the sport; however, their track performance would seem to substantiate these claims.
Re: the F1V10 engine our question is from what are we deriving all this energy, all the extra brake horsepower? In view of the fact that intake or breathing moment has been reduced by almost 50%, with exhaust and scavenging moment reduced by a similar constriction, and with friction losses, rotational turbulence by the crankshaft, rotary motion of the camshaft and flywheel substantially increased. These constraints must be calculated on the order of ×3 or 18,000 RPM. The only single advantage that this F1V10 engine has is the pneumatic closing of the valves, and mechanically that certainly cannot account for the enormous increase in brake horsepower output. As we know, it is the opening of the valves that absorbs the energy, not the closing. The pneumatic implementation for F1V10 is to prevent high RPM (valve float) renitence to closing or seating the valves. However, this power increase comes with a high fuel consumption of approximately 4 MPG, which makes it inappropriate for EFR application. The rational explanation for the gain in power output from the F1V10 engine is due to the very high RPM on the combustion or third cycle of this four-cycle engine. At this very high RPM, the thermodynamic pressure does not have sufficient time to become completely decreased or diminished while still having a favorable or prevalent angle on the crankpin journal. (The F1V10 engine is used by 20+ international competitors and is manufactured by about six different engine companies in accordance with FIA specifications and is subject to strict scrutiny by FIA authority.)
Trigonometric or trigonal linkage system
Tri-go-nal (adj.): Relating to, or being the division of the hexagonal crystal system or the forms belonging to it characterized by a vertical, (or in this specification, angular) axis of threefold symmetry.

The manner or method by which this coupling is done must be tractable to accommodate linkage angle change (which is no more acute than existing mechanisms). The means can be by pin and bushing or any other sturdy mechanism to accommodate this vacillating coupling, by this means the maximum explosive force and thermodynamic pressure can be directed to a crankpin angle, wherein the crank journals are not in vertical or in-line formation, therefore forces and pressure can be applied to the rotary motion of crankshaft and flywheel assembly at a better leverage or dominant angle, while thermodynamic pressure has not yet become weakened or depreciated. By this means, heat and friction losses will be diminished, less fuel will be consumed, increased torque and horsepower will be axiomatic.
