What is a PDT Engine?

It is a new engine concept that has been in the works for forty years. The Positive Displacement Turbine Engine concept is to present day engines; as the Digital Cell Phone is to the Analogue Telephone tethered to the wall.

All Internal Combustion Engines power events follow this sequence, Intake, Compression, Ignition & Power, then Exhaust. In Thermodynamics’ of this process is an Exothermic reaction. In the PDT concept that sequence is modified to accommodate an additional chemical reaction that cannot be added to or applied in a reciprocating engine. This reaction is the opposite of the Exothermic reaction and is called an Endothermic reaction.

• Endothermic reactions are not explosive, but absorb thermal energy and need to perform work in order to function properly. This process can be observed in a Steam Turbine that drives a generator that produces power at our local power stations. Steam enters the turbine at about 1200 PSI and 1200 degrees Fahrenheit. Steam travels 90 feet through the turbine in about 1/30 of a second and comes out the other end at about 200 degrees Fahrenheit, which is less 1000 degrees of thermal energy that has been converted into shaft torque in the turbine and drives the generator.

Mentioned earlier, there are four events to combustion of a reciprocating engine. The PDT has a continuous intake rotary compressor that transfers the compressed air to an indirect combustion chamber which in turn, when fuel is added, fires into an expansion chamber that cycles the burning gasses in a cyclonic turbulent flow of supersonic gasses promoting complete oxidation of the engines fuel. In addition to the Exothermic process an Endothermic reaction is nurtured, producing nearly 3000 additional psi to its normal combustion pressure at full throttle. The rotating crescent piston and expansion chamber holds the expanding gasses in subjection for more than a full rotation giving the engine a 360° duty cycle, and at 2000 RPM the engine reproduces the Exo-Endothermic sequential reaction more than 33 times per second. This energy captured and used by the PDT but is fuel wasted, and expelled out the exhaust and radiator of our present used auto engines.

The new rotary Positive Displacement Turbine IC Engine is more than 94% mechanically efficient, close to 95% thermally efficient, giving its exhaust a low thermal signature. Standard manufacturing processes are comparable to that of a reciprocating engine. Its size though, is about 1/3 that of its competition drastically increasing the power to weight ratio. It can run on #2 Diesel, JP4, or a Special Containerized Fuel and a Catalyst for maximum economy. It consumes roughly 10% of the fuel compared to reciprocating engines, thereby reducing CO2 emissions 90%. For the first time an internal combustion engine can be built on a scale large enough to develop 50 – 100 Megawatts without massive infrastructure, cooling, or pollution. This is NOT too good to be true!
