Re: F20c Piston- dome volume (wildoutwhitegsr)
i found this for you
<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by My baby sisters best friends step uncle's wifes sisters boss »</TD></TR><TR><TD CLASS="quote">The combustion chamber averages 53.6 cc +/- 0.2 cc in volume
The thickness of stock compressed headgasket is approximately 0.5-0.75 mm.
Thus total volume of chamber + headgasket is approximately equal to:
(8.7/2)^2*Pi*0.05 + 53.6 = 56.6 cc
You can also assume that other misc crevice volume in the chamber will add at least 0.5 cc to volume, putting us somewhere between 57 and 57.5 cc for total combustion volume.
Obviously, this is too large to obtain an 11.1:1 compression ratio. Given a 499.5 cc swept volume per cylinder, total chamber volume must be:
(499.5 + x)/x = 11.1 or x = 499.5/10.1 = 49.5 cc.
This tells us that the piston dome (barring any glaring crevice volumes overlooked such as a piston severely below zero deck height - more than 0.5 mm) must be in the range of 7.5-8 cc in volume. </TD></TR></TABLE>
