Atomisation

[bill.shurvinton at nokia.com]

Interesting...I must admit that I had thought that, under part throttle,
as the runner velocity was low it was better to inject at the narrowest
point. I hadn't thought about whether the poorer atomisation would
countermand this.

I guess we are assuming here that a TBI system will have a larger ID
than the carb as it will not need a venturi?

 Running throttled, steady state - yes.  A TBI system can match a
carburetor under those conditions, but a port injection setup can't.

 Part-throttle cruise is where carbs and TBIs rule, but that doesn't
play much of a part in EPA smog or mileage testing.  They assume
everyone lives in an anthill of traffic.  However, for some of us, part
throttle cruise is the dominant driving mode.
