Abstract

The Engine Supercooler for Fuel Burning Engines uses liquid nitrogen (or any other supercool medium) to cool engine components to a temperature above fuel freezing in order to decrease the probability of detonation. For the purpose of this patent supercooling is defined as cooling the engine and through it its fuel-gas mixtures to temperatures above fuel freezing.

Description

The Engine Supercooler for Fuel Burning Engines
Description
The Engine Supercooler for Fuel Burning Engines uses a supercool medium to supercool an engine and the engine's components in order to decrease the probability of detonation thus allowing increases in horsepower, torque, redlirie, compression ratio, and forced induction boost; which in turn result in greater fuel efficiency.
Background:
Current supercharged, turbocharged, and other forced induction systems (for example nitrous oxide) cause an increase in power per L by forcing more air (or oxygenated gas) into the engine's cylinder(s). An alternate method of increasing power is to increase compression. The limit of these power increased is caused by detonation, (spontaneous combustion of the fuel and gas mixture caused by residual heat). Attempts have been made to circumvent this by using intercoolers (aka aftercoolers) to cool the forced air (or oxygenated gas) and by other means or controlling the temperature of the gas (for example nitrous oxide has a low injection temperature). Other causes of detonation are increased compression, and voluntary detonation in diesel engines. However so far the temperature of the cylinder(s) (including the piston) has been overlooked (it and it's equivalent in rotary engines are the main cause of detonation). Upon injection, the fuel-gas mixture's temperature cannot cause detonation. As the fuel is heated by the engine's temperature, the probability of detonation increases. Therefore cooling the cylinder (or the cylinder's equivalent) will lower the temperature of the fuel-gas mixture enough to avoid detonation (or postpone it in diesel engines)
Advantages of The Engine Supercooler for Fuel Burning Engines:
The Engine Supercooler for Fuel Burning Engines cools the engine mainly by cooling the cylinder(s) (or the cylinder's equivalent) allowing for increased compression, increased forced induction boost, increased efficiency, use of lower octane fuels, decreased exhaust, increased power, and delayed or decreased probability of detonation, due to lowered engine and fuel-gas temperatures. Advantages of using Liquid Nitrogen as a supercool medium:
Liquid nitrogen has a very low temperature, and as it absorbs heat it becomes a cold gas (which can still assist in cooling the engine). Controlling the engine's temperature then becomes simply a matter of controlling the flow of liquid nitrogen. The easiest way of controlling the flow of nitrogen is by using a valve which allows nitrogen to flow into the area known as 10 in Fig 2., however a thermometer connected to the valve can also be used to control the flow (valve 18 can double as the cutoff valve and the flow control valve). Since the atmosphere already contains a large percentage of nitrogen it is available cheaply, and can be safely vented into the atmosphere.
Other supercool mediums can be used, and may have advantages over Liquid Nitrogen, although some are harmful.
For the purpose of the diagrams and descriptions, a cylinder based engine, on a four step cycle will be described,
The steps are 1. Injection 2. Compression 3. Combustion 4. Exhaust.
During steps 1 and 3 the piston moves down, during steps 2 and 4 the piston moves up.
Figure 2 represents the supercooling system, while Figure 1 represents the supercooling system with respect to the cylinder(s). Figure 1 is contained in Figure 2 as part of 10.
For diagrams the following numbers are assigned
1. Normal Cylinder with a, b, c, d, and e class valves
2. a class valve(s) (fuel-gas injection)
3. b class valve(s) (liquid nitrogen or other supercool medium injection)
4. c class valve(s) (exhaust)
5. External cylinder (containing a flow of liquid nitrogen or other supercool medium)
6. Tubing (containing a flow of liquid nitrogen or other supercool medium)
7. d class valve(s) (liquid nitrogen or other supercool medium)
8. e class valve(s) (pressure valve, prevents excess pressure from building up beneath the piston) can lead to either the atmosphere or the recompression tank
9. f class valve(s) can be placed anywhere along a flow of liquid nitrogen to prevent excess pressure from building, the f class valve can lead to either the atmosphere or the recompression tank
10. The entire engine Recompression tank Compressed tank

Liquid Nitrogen cutoff valve (when engine is off cutoff valve is closed), and flow control valve Note
-The F class valves should only open under extreme pressure as a last resort
-12 must be very well insulated from all heat to avoid expansion of nitrogen when engine is not running
-All valves are unidirectional
-All liquid nitrogen (or other supercool medium) lines are unidirectional
-For methods 1, 3, 5, and 8, d and e class valves do not exist.
-For methods 2, 4, 6, 7, and 9 the d class valve lets a slow stream of liquid nitrogen (or other supercool medium) into the area under the piston
-For methods 5, 6, 7, 8, and 9 class b valves do not exist
-11 should have the capacity to hold all the nitrogen (or other supercool medium) under low pressure
-12's 9 should (but need not) lead to 11, if it does not lead to 11 it must vent into the atmosphere
(this is a safety feature)
