Which additional mechanism stores hydrocarbons during combustion?

  • A.Absorption into the oil film and deposits
  • B.Adsorption on the spark plug, which releases the fuel during the exhaust stroke of the following cycle
  • C.Nothing
  • D.Dissolution of fuel into the oil layer on the cylinder wall and into porous combustion deposits, released later

Answer: A

Fuel dissolves into the oil film under pressure and desorbs when the pressure falls. The last option describes exactly that mechanism, which makes it a correct and more detailed version of the same answer. The order in which the effects act is what decides the outcome, so it is worth establishing first. Reading the definition literally, rather than recalling a summary, avoids the usual confusion. Framing the question as which quantity the change acts upon makes the answer follow without calculation.
