Sunny Monday morning, Still MC at home, can't sit yet, lay on bed, enable Windows 7 magnifier on 24" LCD which is 10 feet from me. Nothing can do, so just open and read the attachment by mengsuan last week about Campro IAFM research.
The thesis not that 'hard' even i'm not a mechanical engineer, can understand the basic and what they do. After finished it, my conclusion is:
1. This IAFM solution is not a cincai work, it does have proper research and investigation before it introduced. Although plagued by structurer defect of IAFM which cause annoying tak tak noise when mass produced, most probably is due to tooling and material design.
2. In this thesis, IAFM is call NDIM (Naturally Dual Intake Manifold).
3. The thesis doesn't talking about short and long runner split by valve, it just stated the air will enter either short/long runner based on pressure which affected by engine speed. So this explain our discussion last week which the length of the manifold is actually adjusted continuous, in correct term, air is 'auto driven' through short/long runner based on pressure, neither the length of the manifold adjusted itself nor the air is redirect by valve switching. The change in torque is smooth and the IAFM operation is transparent to the user, so it shouldn't have any 'kick' effect. Anyway, i'm not sure whether this thesis is fully implemented or not, maybe later they add valve to split the runner, else why it will have IAFM tak tak noise?
4. Proud of Malaysia as this solution is investigated by local U.
That's all, haha...
