Opposed Piston EngineA reciprocating engine, also frequently known as a piston engine, is an engine that makes use of a single or far more pistons to convert stress into a rotating motion. With two pistons in each and every cylinder and very engineered 360 degree circumferential intake/exhaust ports, scavenging in the opoc engine is able to be optimized. The end outcome is a loss in thermal efficiency, compared to a conventional engine. So it beats all other designs beneath when it comes to converting the piston thrust power to torque energy.

Further objects of the invention are to supply a novel and improved omnitorque opposed piston engine which is basic in its basic type, may be manufactured with conventional, readily offered components with a minimum of particular machining operations, and is a low-cost, neat appearing, rugged and sturdy unit. The correct and only 80% thermally effective engine is the 1 talked about by Professor Fred Main in a documentary under.

Mainly because of the 90 degree lead of the secondary crankshaft, the leading dead center positions of every piston, indicated as TDC, lap each and every other and the closest position between the pistons is in between these lapped positions at about 45 degrees previous best dead center of the secondary piston movement, and 45 degrees prior to top rated dead center of the main piston movement.

This slight shift from the perfect operational arrangement does not impair the efiiciency of the engine operation, but does minimize its rated output slightly. The perform cycle commences with ignition at the point 45 degrees previous best dead center of the secondary piston and 45 degrees just before prime dead center of the primary piston, exactly where maximum compression occurs.

FIGURE 17 illustrates the position of the pistons in the course of the compression cycle as when the secondary piston is at leading dead center and the principal piston is 90 degrees just before prime dead center. Comparing the heat transfer on a specific surface location to the mechanical transfer of power on a comparable surface of a piston crown is not possible, because these are two totally unique types of power transfer that use totally various formulae to calculate the transfer.
