Interesting...
If we use N/A injectors then due to the lower break pressures  injection
will start earlier.
Poorer atomisation? Maybe.
    Do we want ultra atomisation? Doesn't this lead to explosion rather
than burning? Hence a noisier engine which is why TDi's squirt in two
stages (don't they?)
 Only boy racers need to inject quickly for their gasser like rpms... James
etc LOL
Penalty of higher pressures is more work done by pump and belt and engine
leading to higher wear of first two and all for the search for better
atomisation. Lord Jake didn't feel there was much if any benefit to higher
pressures economy wise IIRC
Secret to good fuel economy apart from driving style is correctly operating
injectors [at any pressure] and experimental tweaking of pump/aneroid.
