Re: [T3] Dual 40 DCNF Carbs
<x-flowed>> Aren't air flow and air mass metering the same thing?
D-Jet was different in that it sensed air pressure. I think it's at
least
somewhat interesting that the first generation system used air
pressure (or
vacuum) to meter fuel, which is the same principle that carbs work on.
jim,
they are not. air flow just measures air volume with the help of the
spring-loaded flap. air mass metering also takes the ambient air
density/pressure and temperature into account. it uses a small heated
wire in the intake air stream that gets cooled down by the air moving
through the intake unit. the air mass is calculated from how much this
wire gets cooled down by the air.
