D-4 Vs. Valvematic

[SF695]

If i understood it correctly, there is a problem fitting D-4(direct injection) on the same engine as Valvematic(variable valve lift), because of limited space on the top. Please correct me if i'm wrong

The question then is, which is better? BMW seem to have dropped their Valvetronic system in favor of direct injection, Toyota seem to do the oposite.

Also, will it be posible in a near future to see both systems on the same engine?

Anyone?

Sorry but it does not seem that anyone has the answer you are looking for.... I know I certainly don't :(

Well, i guess anything will be possible in the future. Question just is, how near a future.

I was just wondering, if it was an economical issue or a technological one

the valve-matic system has been brought in due to emissions, seen the set up for first time the other day.

Sure, but that doesn't explain why they halted the production of D4, unless the 2 don't work together

i'll have to check in work, i'm still waitin to hear more bout the engine works exactly but i'm sure it's still got direct injection as well tho
