Other sources quote the ignition temperature of a flammable mixture of petrol and air (1.4 to 7.6%) in a range between 230 and 280°C (https://hypertextbook.com/facts/2003/Sha...pher.shtml)

With the suggested C temperatures below I would think that some other parts of the combustion chamber could 'spark' auto ignition then (or am I totally confused) ?

  1. Intake manifold : 60
  2. Intake valve : 250
  3. Spark plug : 600
  4. Exhaust valve : 650
  5. Exhaust gases : 450
  6. Piston face : 300
  7. Cylinder wall : 185
  8. Piston ring : 220
  9. Piston skirt : 190
  10. Coolant : 105
  11. Engine oil : 70
