Ignition interval
The ignition interval indicates in crank angle degrees the interval at which the work cycles of an internal combustion engine follow. The more cylinders, the smaller the ignition interval. This influences the engine running, which is therefore quieter, and the torque curve, which becomes more uniform due to small ignition intervals. The ignition intervals of a four-stroke reciprocating engine are between 720 ° for a single-cylinder engine and 60 ° for a twelve-cylinder engine . The formula for the ignition interval with normal offset is: 720 ° CA: number of cylinders = ignition interval. Other firing intervals result, for example, from the big bang firing order .
