hey i have a question and well i was wondering how BMW or other motor company's can make a GASOLINE direct injection motor without the gas vaporizing before it goes into the chamber... i'm really puzzled with this and was wondering if any one could shed some light on it...
p.s i'm not asking about direct injection deisel's i know how they work

The precise control over fuel and timing permits the instantaneous mixture atomization.

so they don't use any thing to keep it from vaporizing?
the chamber gets soo hot that it's hard to even time it right without all the gas vaporizing in the injectors.
idk do you have a diagram for it or something?

thanks

Mazdaspeed 3, Mazdaspeed 6 and their SUV all use direct injection.

uhh cool but if you could tell me how the fuel injectors work without vaporization in the injector then it would solve my problem

The 2.3 turbo in the mazdaspeed 3, 6 and CX7 are actually ford motors

the injectors work at a much higher presure then standard injectors.... they spray at upwords to 40,000 psi...

Pretty sure vaporization is what you want, since gasoline vapors are what burns, not the liquid. The injectors are spraying the fuel into the chamber right before combustion right?
