There were four engine types historically.
Now there are five engine types:
1) Piston- Otto or Diesel
2) Turbine- Jet or Turbo Prop
3) Electrical- Battery or Fuel Cell
4) Hybrid- Electric, Air, Hydraulic
5) New Engine Type- A combination of all types in one
The picture to the left shows the efficiencies. 0% efficiency means the engine needs to idle to operate and thus wastes fuel/energy when stopped. An electric motor and this New Engine type do NOT need to idle and therefore have an effective lower limit of efficiency where they are "turned off" to a degree.
An electric motor requires current to hold a static (no rotating, stopped) torque, whereas the New Engine Type can hold a torque without running. This is valuable in several situations.
Below are listed the characteristics and features of each type. This is by no means a complete list.
Two Types of Motors:
1) For wings (smaller)
2) For compressor and low power drive
Two types of energy storage:
1) Compressed air used for:
2) Small Battery in Vehicle is used for:
(Found in cars, trucks, ATVs, hydraulic equipment and small airplanes.)
Jet engines used in Airlines, fighter jets, power generation
Medium Turbo props used in commuter airlines, large helicopters
Small turbo props used in fast and small GA airplanes
Fuel Cell Issues
General Electricity and battery costs found in Battery EVs and Fuel Cell EVs
Question: What is meant by a "type" of engine?
Answer: The word type means:
In this case, the thing is an engine, and the common traits or characteristics are shown above. This New Engine Type is unique from all other engines types.
In essence, the New Engine Type is a new kind of engine, and is a combination of traits found in other engines types but applied differently or in a fashion that adds value and synergies to the system not found in other types of engine systems. It is the "heart" of the future of energy.
