Pollution - Global warming

We can blame hydrocarbon fuels for Global Warming and Ozone fog over our cities; however, it is not the fuel but the inability of the engines used today to burn the fuel completely or apply the energy to the work it is supposed to do. In reality, one of the greatest contributers to the pollution generated is the waste of hydrocarbon fuels in the reciprocating automotive engine.

It’s a chilling fact that less than .10 cents out of every dollar you spend on gasoline starts your car and pushes it down the road. Yeah, really! The rest of your $3.00 + per gallon fuels energy goes out the exhaust and radiator! Check it out for yourself.
The engine in your car or truck is likely a four-cycle engine (with the exception of SAAB) with four to ten cylinders. Each cycle equals 180º of a circle. The four cycles are Intake, Compression, Power, Exhaust totaling 720º equaling two (2) rotations before that cylinder is ready to fire again. Only the power stroke does the work the rest represents drag. The more cylinders in an engine the more drag. (Resistance to work) In the180º Power stroke the first 30º and the last 40ºare worthless for push, it is like standing on a bicycle pedal. That leaves 110º of the 180º Power stroke to do all the work!
110º ÷720º = 15.2 % of the each engines cylinder dose the work for that engine!
We loose an additional 6% from that 15.2% to the Drag in the operation of the engine through its alternator, water pump, oil pump, and barring friction.
15.2% - 6% = 9.2 % of the Mechanical Physics pushing your car or truck!
Thermal Energy of your Fuel is Subtracted
Engine design engineers agree that three quarters, of the fuels thermal energy (Heat) is lost from the engine’s combustion through the radiator, and through the exhaust leaving less than one fourth or 25% to turn the crankshaft in each Power stroke!
9.2% ÷ 25% = 2.3% is the overall efficiency given to the reciprocating car engine!
Allowing for variations the automotive engine efficiency of today is
less than 10% maximum!

That is equivalent to less than .10 Cents of every dollar you spend at the pump for fuel!
There is now the new PDT Engine concept that is more than 95% fuel-efficient and it burns its fuel completely. The Positive Displacement Turbine is an exo-endothermic hybrid technology. It removes the ash from its exhaust before it is released back into the atmosphere. This engine will reduce Carbon Dioxide emissions by more than 90-95% and increase your vehicles performance and economy tremendously!
PDT has a completely NEW approach to energy needs:
