Hmmm - Ok, but better expressed in terms of their inability to light up
the mix until there's enough pressure present, whereas a SI engine can
light off the mix virtually anywhere the designers decide on doing so.
This is one of the reasons that diesel engines aren't too flash at
acceleration far more so than due to mass of components.
