Technician a says that the octane rating of gasoline is the measure of its antiknock properties. technician b says that normal combustion occurs smoothly and progresses across the combustion chamber from the point of ignition. who is correct?

Both technicians are correct.

It is true when technician A says that the octane rating of a gasoline is used to measure the antiknock properties of a gasoline. Octane rating measure the resistance of gasoline to engine knocking in spark-ignition internal combustion of engines.

On other hand, technician B is also correct because a normal combustion occurs smoothly, controlled burning of air and fuel mixture then progresses across the combustion chamber from the point of ignition.

where is the graph? post the graph then ill come back and
