I was analyzing the Lamborghini Aventador's tech. specs. and it is given Bore x Stroke 95mm x 76.4mm and compression ratio 11.8:1. Then I calculated the volume of displacement and it's 541.5 cm^3 for each cylinder. Then I know the compression ratio as $$\frac{V_1 + V_2}{V_2} = C.R$$ $$ V_1=Displacement,$$ $$ V_2 =Combustion Chamber$$
So V_1 = 10.8 V_2 and from here I found the V_2 as 50 cm^3 and divided it by 70.9 cm^2 ( area of the piston) to be able to find the approximate height of combustion chamber. And I got 0.71 cm.
It seemed weird to me, I grabbed a ruler and it's really really small. I couldn't imagine that a combustion chamber can be such small. There is no place even for manifolds to open and close. Where did I make mistake?
Thanks.
