Endothermic/Exothermic new combustion cycle.

[SPOrotary]

I have a need for some smart chemical professionals!

My problem:
I am in the process of making a test system to test a new combustion cycle. The problem is that I need a few chemicals and they need to have certain special qualities.

First: I need to know if there are any endothermic processes that involve Nitrogen? if there is what are they?

Second: I need to know if there is an endothermic process that results in a solid that can react exothermically with petrol/ethanol/iron/aluminium...

Also because my knowledge in the field of chemicals is fairly limited I would like the common names if possible (but don't forget the technical details).


Thanks in advance for the help.

Liquify nitrogen. potassium permangenate is a solid that reacts exothermically with glycerin.
