- Attachment: diagram of Wave-Disk Generator
- After 100 years it is about time the internal combustion reciprocating engine got replaced. Piston engines are 15% efficient on consuming the energy in gasoline. The world is running low on oil. We need a better solution.
- There is one coming in 2013. Prototype engines are already working. It is a gas driven engine but a rotary engine that powers an electric generator. This new vehicle would:
-------------------- 60% efficiency, 3.5 times better than today’s cars.
-------------------- 500 mile driving range on fill up.
-------------------- 30% less weight
-------------------- 30% cheaper to manufacture.
-------------------- 90% fewer exhaust emissions
- The new engine is a shock-wave engine. A gas turbine with the name “ Wave Disk Generator”. It has no pistons. It is a rotary engine. Like a jet engine with a spinning disk of curved blades except these blades are contained is combustion chambers. The engine has wave-like channels that trap and mix air and fuel as the rotor spins. When the central inlets are blocked the pressure builds up inside the chamber creating a shockwave that ignites the fuel and spins the rotor.
-The engine works at a higher temperature than reciprocating engines but does not require a cooling system. The rotating blades do not spin as fast as a jet engine or other turbine engines so it does not require the expensive high strength materials.
- With not transmission, no crankshaft, no pistons, no valves, no fuel compression, no cooling system the system will be 1,000 pounds lighter than today’s cars. The engine can be held in one hand. It is designed to connect its central shaft to an electric generator. The engine will rotate at maximum efficiency and the generator will charge batteries. The batteries will provide the instant acceleration and hill climbing power needed.
- A plug in hybrid would have regenerative braking that would also charge the batteries. They could even have electric generator shock absorbers that could turn the suspension system in to a charging system. 500 miles between fill ups and recharging.
- The Wave-Disk Generator engine is only 33 horsepower, 25,000 watts. But, engine efficiency could exceed 65%.
- Hot, pressurized air and fuel enter the gaps between the blades from a central spindle. High pressure shockwaves ignite the fuel at high temperatures and the expanding gas spins the rotor blades. The rotor’s crankshaft powers and electric generator that drives the electric motors at the wheels. The running engine requires split second timing for combustion and precise shaping of the blade geometries.
- The math involved is very complex, yet, the basic thermodynamics for a heat engine is dirt simple. The efficiency of a heat engine depends solely on the difference between the hot and cold temperature reservoirs. One minus the ratio of the cold temperature to the hot temperature.
------------------- Maximum Efficiency = 1 - Tc // Th
- This equation is Carnot’s Theorem from the second law of thermodynamics which applies to all engines that convert thermal energy to work. Fuel cells and batteries convert chemical energy to work and have different efficiency formulas.
- The Wave-Disk Generator hybrids could be on the road in 2013. This would enter us into a new era of electric vehicles. It could result in electric generators for many other purposes as well. To get a better idea of the small engine that does the work see the video:
