Pre-ignition Pre-ignition Pre-ignition (or preignition) in a spark-ignition engine is a technically different phenomenon from engine knocking, and describes the event wherein the air/fuel mixture in the cylinder ignites before the spark plug fires. Pre-ignition is initiated by an ignition source other than the spark, such as hot spots in the combustion chamber, a spark plug that runs too hot for the application, or carbonaceous deposits in the combustion chamber heated to incandescence by previous engine combustion events. The phenomenon is also referred to as 'after-run', or 'run-on' or sometimes dieseling, when it causes the engine to carry on running after
Ignition SCADA Ignition SCADA Ignition is an Integrated Software Platform for SCADA systems released by Inductive Automation in January 2010. It is based on an SQL Database-centric architecture. Ignition features cross platform web based deployment through Java Web Start technology. The Ignition platform has three main components: the Ignition Gateway, the Designer, and runtime clients. Independent modules provide separate functionality in any or all of the platform components. Ignition SCADA modules provide features such as: Real-Time Status Control, Alarming, Reporting, Data Acquisition, Scripting, Scheduling, MES, and Mobile support. Ignition received the 2011 Duke's Choice award at the JavaOne conference in San Francisco,
