Liquid nitrogen generator engine

well let us assume that the outside air temperature is 15 ° C and that we have water at 15 ° C, once passed in the engine the water will be at 10 ° C and therefore it will be necessary reheat to 15 ° c in a water and outdoor air radiator.

we can also use all the low temperature heat sources available. geothermal energy, factory rejection, thermal power station, nuclear power and increase the efficiency in design. if the water is at 50 ° C rather than 15 ° C, the energy recovered is increased by 10%.

Ah! So you should still include on your initial process diagram an element that is nevertheless important in any thermodynamic process, the hot spring!

And the consumer auxiliaries, at least one pump which recirculates the recovered water to an exchanger and one which allows it to be injected after reheating to 300bar in the engine.

It is not going to be very practical in our regions for a vehicle application if it only works above an air temperature of 15 ° C ....

the hot spring is described in more detail in the third diagram.
the consumption of the water pump is the energy required to break the water into a fine droplet and circulate it, ie 3 bar. we have for 1 kg of liquid nitrogen which produce 240 wh a consumption of 25 liters of water at 3 bar.

if it's colder, cooler water is injected. it still works. instead of having a relaxation at 15 ° C we have a relaxation at -5 ° C so we go from 300 ° K to 280 ° k so we lose 7% of energy.

What third scheme?

3bar you say? To inject into an engine where the working fluid is injected at 300bar?

Relaxation at -5 ° C, with a high percentage of water in the relaxed mixture?

Explain this to me.

the diagrams:

the water pump which injects water into the engine is assisted by the pressure of nitrogen in the chamber there is just an overpressure of 3 bar applied to spray the water.

there are many ice washers on cars that operate at -20 ° C

Sorry, the diagrams are difficult to read and for what I see little explicit. So I don't understand how the water is injected with a pressure of 3 bar.

Windshield washers that operate at -20 ° C are seldom with pure water.

the diagrams does not explain how the water is injected. 3 bar is an overpressure and not an injection pressure, if the pressure in the chamber is 100 bar, the water is injected at 103 bar.

after actually you have to think of putting a washer fluid to adapt when it is cold. It's obvious.

Sunday: "the consumption of the water pump is the energy required to break the water into a fine droplet and circulate it, i.e. 3 bar"

Today: "the diagrams do not explain how the water is injected. 3 bar is an overpressure and not an injection pressure, if the pressure in the chamber is 100 bar, the water is injected at 103 bar. "

Well then! It's magic!
