Hey guys, what is the equation that link at what pressure and temperature gasoline self ignites?

Like, lets say in diesel engines at 25:1 compression; what temperature must the air/fuel be to self ignite?

Also, why couldn't you just do 100:1 compression and be able to self ignite gas at much lower temperatures??

Thanks!
