Xu 1.9 D6B- Piston To Deck Clearance

[jimmi 0 1 Cars]

I'm trying to calculate compression ratio....Anyone know what piston deck height clearance is for 1.6 pistons... and for 1.9 pistons (if they are not the same -considering same stroke and bore) ?

Can't answer your question but can say that the pistons are different, 1.9's are domed 1.6's are flat

From memory my engine is fitted with 1.6 pistons...

From memory, (cant remember for sure though) I think that measurment is in the technical data section of the Haynes manual.

O.T.

1.6 arent flat, just not as deep a dish as xu9ja

I checked Haynes manual... no mention of piston to deck height ..only the liner height above block deck... I assume pistons do not go right to top of the liners ??

Compression height for all pistons is 37.12mm. Ie they sit 0.38mm down the bore. 1.6 and DFZ pistons have a 9cc dish. DKZ has 16cc and D6B has 15cc.

Anyone know what the thickness (mm) of a 1.20mm headgasket -once it is torqued-down onto engine block ? ( I have sent PAYEN an email asking same question but will be Monday before they reply)....?

[petert 588]

most reduce by 0.1mm

most reduce by 0.1mm

Thanks again Peter....I will post reply from Payen.

Does no1 cylinder sit tdc on timing set up doesn't look right when setting with pins

no, they sit mid stroke.
