not just EFI :-) but yes. a carburetor *MUST* introduce a restriction into the airstream. it is the pressure drop through the venturi that makes it work in the first place. FI throttle bodies present very little restriction and only meter the air to match what the engine requires. (and in the case of slidevalve TB's - ZERO restriction...) Diesels - which always operate in excess air - don't even have throttles - their injection systems just meter fuel. (exception - okay - modern computer-controlled Diesels like TDI's have throttles for emissions, to help control the NOx...) |
