Direct Injection. High pressure fuel injectors are placed in the combustion chambers, as opposed to the intake runners in the intake manifold, and the fuel is atomized a lot finer so it burns more completely, increasing efficiency and lowering emissions. I think the LLT runs something like 2000-plus psi in the fuel rails, opposed to many MPFI engines, like the LS3/L99, where they run somewhere from 40-50-os-so psi.[/QUOTE]
Ok, Thanks..
