Squish (piston engine)
In an engine designed to use the squish effect, at top dead centre (TDC) the piston crown comes very close, (typically less than 1mm), to the cylinder head. The gases are suddenly "squished" out within the combustion chamber, creating turbulence which promotes thorough fuel/air mixing, a factor beneficial to efficient combustion. Squish effect may be found in ohv and ohc engines, including engines with a Heron cylinder head.
