The author proposes to determine what features of spark-plug construction cause preignition and how this preignition manifests itself. To this end observed conditions on an Hispano-Suiza aviation ...

Preignition occurs when the combustion chambers ignites prior to the spark event. This causes advanced combustion timing which can lead to heavy engine knock and catastrophic engine damage.

Low-speed preignition can be a serious cause for concern for gasoline direct injection, especially those equipped with turbochargers, where higher-than-normal intake charge pressures can increase ...

This month Willie reviews the "pinging" noise, the difference between preignition and detonation, what causes it, and why its bad for your engine all inside Four Wheeler Magazine.

Mixtures that cause the plugs to read lean might contribute to preignition or detonation. 2. Spark Advance:Ignition timing has one of the greatest effects on heat-range choice.

Preignition, when gasoline ignites before the spark plug fires, can cause significant damage to an engine. When a truckmaker calls for a certain octane level, ...
