Opposed Piston EngineTwo stroke engines are favorites of everybody who desires a genuinely compact engine with lots of energy, there are fewer parts and energy delivery on each and every stroke. With two pistons in each and every cylinder and highly 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 standard engine. So it beats all other styles under when it comes to converting the piston thrust power to torque power.

Additional objects of the invention are to supply a novel and enhanced omnitorque opposed piston engine which is straightforward in its fundamental kind, may well be manufactured with conventional, readily offered elements with a minimum of special machining operations, and is a low-price, neat appearing, rugged and durable unit. The true and only 80% thermally effective engine is the a single talked about by Professor Fred Significant in a documentary below.

FIGURE 17 illustrates the position of the pistons for the duration of the compression cycle as when the secondary piston is at best dead center and the main piston is 90 degrees prior to best dead center. Comparing the heat transfer on a particular surface region to the mechanical transfer of power on a related surface of a piston crown is not feasible, because these are 2 completely distinct types of power transfer that use completely diverse formulae to calculate the transfer. FIGURE 24 is a sectional plan view of a single cylinder, four-cycle, opposed piston engine similar to the view shown at FIG.

Another object of the invention is to present in a novel and improved omnitorque opposed piston engine of the internal combustion engine type, means for varying the compression ratio throughout operation of the engine to greater and …

Opposed Piston EngineThe basic design and style of the 4-stroke piston engine has been kicking around for about 150 years. So the architecture or geometry of an engine doesn’t matter or affect the how substantially energy or effective the engine is at extracting workable energy from the fuel. Since the pressure drop is doubled, only half as substantially power is transferred to each and every piston, resulting in the precise very same quantity of energy transferred to the piston crowns of your miracle engine.

This slight shift from the perfect operational arrangement does not impair the efiiciency of the engine operation, but does lower its rated output slightly. The operate cycle commences with ignition at the point 45 degrees past top dead center of the secondary piston and 45 degrees just before best dead center of the main piston, where maximum compression happens.

The movements of piston INCREASES THE VOLUME holding the gases, which will reduce stress, as a result heat. A one cylinder engine electrically turbo charged engine with a displacement of one particular liter IS generating 900 Horse energy, with exact same quantity of fuel utilized in similar size engine, it is at least three occasions a lot more effective, while a regular american engine of five liter 8 cylinders produces 350 horse powers.

This layout gives superior scavenging, as gas flow by means of the cylinder is axial rather than radial, and simplifies design of the piston crowns. On the other hand, although the furthestapart position of the pistons is about 45 degrees past bottom dead center of the secondary piston and 45 degrees prior to bottom dead center of the primary piston, it is to be noted that the distance in between the pistons does not drastically reduce until the main piston is at bottom dead center, indicated …

Opposed Piston EnginePrior to World War II, these engines had been utilised just about exclusively on submarines. In this arrangement, a carburetor 62, having a gasoline feedline 63 and a two-branch intake line 64 extending to each crankcase, is mounted on a single side of the engine. This is accomplished in a conventional manner by giving a ridge 60 on the face of the major piston 43 which traverses the piston involving the diametrically opposed inlet and exhaust ports.

It is contemplated that the flywheels 37 will have sufficient inertia and momentum to permit the crank shafts to smoothly roate by way of this return cycle, and it is to be noted that where the engine is composed of two 01 far more cylinders, no issue will exist mainly because the cranks can be timed to present a substantially continuous driving torque upon the engine shafts.

The exhaust port 46, positioned close to the base of the cylinder, is generally closed by the elongated skirt of the piston 43 and opens by movement of the face of the piston therepast as the primary crankshaft moves to bottom dead center and again closes as the crankshaft moves past bottom dead center. Other rewards of modularity contain optimized engine performance, lowered emissions, and an extended solution line. FIGURE 18 is a sectional strategy view of a single cylinder, two cycle, opposed-piston engine comparable to the view shown at FIG.

Efficient combustion in the opoc engine is achieved by very carefully managing the exchange of exhaust gas with fresh air/fuel, by precisely controlling the opening and closing of the intake/exhaust ports, by utilizing our electrically controlled turbocharger to dynamically adjust program stress, and by employing state-of-the-art side-mounted direct-injection injectors to deliver extremely atomized fuel into the combustion chamber which capabilities an revolutionary piston bowl design.…

Opposed Piston EngineSome variations of the Opposed Piston or OP styles use a single crankshaft , such as the Doxford ship engines 1 and the Commer OP truck engines. So, when an opposed piston engine is developed with the very same piston speed as a standard engine of the identical specified power a extremely very good issue takes place – the size of the engine can get substantially smaller sized (as measured by the essential volume displacement of the engine). FIGURE ten is a plan view of a single cylinder opposed piston engine comparable to the showing at FIG. Yet another object of the invention is to present a novel and improved opposed piston engine which may well also advantageously combine cylinder wall ports and valves in productive and efficient arrangements for the operation of the engine.

In a typical Piston+ head engine, the head of the engine a STATIC pressure port or (heat port) , the gases heat the head, and the head heats the cooling water, that requires the heat to the radiator where it is disposed of into ambient air, in other words it ports out heat in its native type with out undertaking and valuable function. One particular of the crankshafts, preferably the primary crankshaft P, incorporates an extension stub 40 which is adapted to connect with a driveshaft or the like to drive the mechanisms to which the engine is connected. The Gasses DO Work on the inner surfaces of the combustion chamber, Cylinder lining, HEAD of the engine and Piston crown.

The phase shift of the two shafts might also be achieved by other mechanisms, not shown, which can be adjusted when the engine is in operation. EM’s opoc® engine does not have a cylinder head or valve train, which are the sources of substantially of …

Opposed Piston EngineWhat do Bill Gates (Microsoft billionaire), Tony Blair (former British Prime Minister), Don Runkle (former head of GM Sophisticated Engineering and former vice chairman and chief engineer at Delphi), and Vinod Khosia (renowned Silicon Valley venture capitalist and co-founder of Sun Microsystems) have in frequent? The larger the initial combustion pressure worth and the decrease the exhausted temperature and stress values the more strong and effective your engine is. regardless of geometry or architecture of engine. Koreyvo, Jumo and Napier Deltic engines utilized one particular piston per cylinder to expose an intake port, and the other to expose an exhaust port. Why can a piston take compression ratios of up to 30:1 when engine head only can take up to 15:1 unless it is Diesel.

In an best arrangement, the operate cycle would be among these intense 45 degree positions above talked about nevertheless, where the inlet and exhaust are fixed ports in the cylinder wall as heretofore described, such is not practical and rather, the function cycle is established by the secondary crankshaft moving its piston 44 among 90 degrees and 270 degrees past top rated dead center, although exhaust occurs when the major piston is at its bottom dead center position as the work cycle is completed.

Efficient combustion in the opoc engine is accomplished by cautiously managing the exchange of exhaust gas with fresh air/fuel, by precisely controlling the opening and closing of the intake/exhaust ports, by using our electrically controlled turbocharger to dynamically adjust method pressure, and by employing state-of-the-art side-mounted direct-injection injectors to deliver hugely atomized fuel into the combustion chamber which functions an revolutionary piston bowl design.

Each and every crank arm 35 carries a connecting rod 41 which connects to its piston by a wristpin 42. The piston 43 of the major crankshaft …
