Block 003 and Block 011 Plots

 

Took these plots as still having problems, down on power, lurching. 

 

These were taken in 3rd gear with WOT

(  *version is just a repeat of (a) but with range of vertical axes changed.

 

I would have thought that EGR (N18) duty cycle should have been much lower (95.5% would be valve fully open?)

 

I would also have thought that Boost Pressure (N75) duty cycle should have increased as speed increased.

 

Have I got the above correct?

Would also welcome any comments on these plots.

 

Thanks

 

*this is just supposed to be a letter b in brackets - it just keeps turning into this daft face.

 

Have now added Run 2 (4th Gear)

 

Should have said Octavia 2 1.9 PD BXE

Ok,think I had it wrong on EGR duty cycle. Big number = EGR valve closed, so 95.5% EGR duty cycle during WOT test is probably OK, I'm still thinking Boost duty cycle should have increased at higher revs though.

And Run 3 

 

Back to 3rd gear like first set.

Similar but not identical to first set.

 

Just a thought, can anyone direct me towards data, or plots, for block 003 and block 011 WOT tests on a known to be good PD engine?

 

Thanks
