Odd Question for you guys...

[Russell]

Hey guys, two questions here, #1 -- Do the newer fuel injected vehicles have some sort of a butterfly valve on it somewhere to restrict airflow to control the motor's RPM, or is it now done entirely based on the amount of fuel the injectors put it?

And #2 -- Does a diesel motor have the injectors directly in the cylinder, or are they in some sort of a pre-combustion chamber or something?

My father and I got into a disscussion tonight, and he feels that none of the newer vehicles have butterfly valves on them, which doesn't make sense to me, since the vehicle is run based on how much air is entering it as far as I know, and that diesel injectors inject directly into the cylinder. I dunno who is right, so we both decided that we'd let you guys decide
