Cylinder Capacity
- In all IC Engines, both compression and expansion cycles occur in the same cylinder. Since the expansion capacity of the combustion
force is much larger than the cylinder capacity, a significant portion of the combustion force exits the cylinder before converted to useful rotating energy. The louder the noise an engine makes when its muffler is removed, the more energy it wastes.
- In a Turbocombustion Engine, compression occurs in a separate combustion chamber, and the combustion force applied directly to a rotor
with capacity between 2.5 to 4 times larger than the cylinder capacity, allowing the entire combustion force to convert to useful rotating energy.
Pressure Angle
- Pressure angle between the connecting rod and the crankshaft in an IC Engine starts from -5 degree at the TDC and goes to near "77"
degree in the middle and moves back to "0" at BDC. This is a very inefficient way of converting reciprocating force to rotating energy, not to mention the side forces applied by the piston to the cylinder walls and the consequential frictions.
- Combustion force in a Turbocombustion Engine applies to the rotor tangential to its perimeter and constantly at 90 degree, the best
possible pressure angle.
Leverage of Force
- In a Turbocombustion Engine, leverage of force---the distance between the rotor firewall and the axis of the rotor---is 5 times more than
the leverage of force (distance between the axis of the crankpin and the axis of its crankshaft) of a typical IC Engine. This is 5 times more torque power.
Power Stroke
- In a typical 4-stroke IC Engine, power stroke occurs once in every two rotations.
- In a Turbocombustion Engine, suction and expansion cycles occur simultaneously in half a rotation, compression and exhaust on the other
half, allowing power stroke to occurs in every rotating cycle. This feature reduces the number of cylinders by 50%.
Throw and Vibration
- In an IC Engines, Throw (kinetic energy) is a major drag on the crankshaft at the exhaust cycles.
- In a Turbocombustion Engine, constant suction and compression by the piston eliminates the throw and, consequently, the vertical
vibration. Since the expansion occurs outside of the cylinder, the piston’s weight is reduced to a minimum and is perfectly balanced with the crankshaft to minimize or eliminate the horizontal vibration.
Variable Compression Ratio System
- Nearly 99% of the IC Engines made today do not have VCR system due to its complexity.
- Turbocombustion Engines can be equipped with a simple VCR system to allow the engine to function at its optimum level under all
atmospheric conditions and using various fuel types.
