5 cylinder and VVT

Postby DCCCL » Fri Jul 01, 2011 2:54 am

Hi,

very new here, a whole lot of plans, and doing some homework before ordering/building a MS3.
I want to use a MS3/MS3x combo on a 5 cylinder volvo engine. From the docs, I found that using the standard 60+2 wheel together with a "half moon" cam wheel should do the job.
But... I have a engine witch has 2 continuous variable camshafts. And I really would like to use them (for MPG reasons).

Q: how do I handle/generate the campulse when using 2cvvt on my volvo B5254T (2007) engine ?

What sensors on the engine report the positions of the two cams? That feedback is required for VVT to work.

Both cams have a VR sensor. I wasn't entirely clear; I know from the documentation that the 60-2 crankwheel and a "half moon" camwheel should work on a standard non VVT 5 cilinder engine.
This engine uses a more complicated wheel on both cams. There is a detailed description available but that's copyrighted by volvo, so I post a summary.

This is the used patern:

Image

Code: Select all
A: Engine speed (RPM) sensor signal.
B: Camshaft position (CMP) sensor signal. From high to low signal when the teeth on the camshaft pulley leave the camshaft position (CMP) sensor.
C: Low engine speed (RPM) sensor signal because of the holes in the flywheel/carrier plate.
D: Top dead center (TDC) cylinder 1, 0°CA (84°CA after hole "C" in the flywheel/carrier plate).
1: Detection of flank 1, reference position 47°CA "D1".
2: Detection of flank 2, reference position 227°CA "D2".
3: Detection of flank 3, reference position 407°CA "D3".
4: Detection of flank 4, reference position 587°CA "D4".



But how "compatible" is this wheel with the fuelinjection and ignition part ?

That should work with the existing MS3 pre1.1 alpha code.

Use "poll level" and then set the correct number of cam teeth. You'll need to choose the correct cam edge - this will likely be "rising edge" at the CPU (matches the falling edge on the cam.)

Ah, thanks. :)

Will this also take care of the moving phase the ignition sees when the cam timing is changed ?

Sorry, English is not my native language. Wanna try Dutch ?

The ignition uses the crank as the primary reference, so that won't be a problem.

Is this B5254T still alive? Im bulding ST focus 2006 engine to Ford sierra. Im having a same project to come. If someone has a working program for that engine could someone send it to me? Sure my dyno service have to see all again but it would help him a lot if i would get those cam timing setups right.

I would also would need a tips to connect and setup that iacv / idle stepper motor right. Its from Mitsubishi evo 8/9.

Im noobie of these things, im trying to help my tuner. He have done lots of cars but non of those has been with 4 teeth and "halfmoon" trigger wheels. Also he has use only regular solenoid idle valves.

Is it possible someone to send me Mitsubishi evo 8/9 setups to see how it shoud be mapped and ST focus or same engine Volvo setups?
