Spectral analysis of ABH and PT cylinder walls

Hello.

Today, after "sufficient" processing time, I have already received some data from us in the laboratory.

I got here from V8 friends a "sample" of a PT cylinder ( 3.6) and one from an ABH engine ( 4.2).
Many thanks to Sven Konrad and Stefan N. .

The rumors of the differences in quality of the engine of the 3.6 and 4.2 in the type D11 should now have been definitively created out of the world.

Thanks also to the Bastian Preindl, who had organized the deliveries.

I will teach pictures and prints of the analyses in the next few days.

In summary, however, the following can be said in advance:

1. the PT and ABH are identical engine block alloys, which do not differ in the least in their composition or surface processing!

2. both samples sent to me are AlSiCu casting alloys

3. both samples sent to me have etched surfaces ( careers).

4. The alloy is called G-AlSi12 and is a "standard material" for high strength demands e.g. in the engine block area.

5. traces of iron ( Fe ~ 0,67 ) were also identified, which is decisive for the above-mentioned strength in point 4.


Oh yes, and a sample had a hair crack from the small cooling water hole starting at the combustion chamber!

I'm still trying to fill the assignment...

Further data will follow in the next few days.

Greetings Manfred M.
