This causes shockwaves and a 'pinging' sound in the engine.

Systems for enhancing preignition conditions of a fusion reaction are disclosed.

The center electrode insulation provides an effective heat transfer path to prevent electrode overheating and preignition.

The ignition circuit is configured subsequent to application of the pre-ignition voltage pulses to apply an ignition pulse to ignite the HID lamp.

The invention relates to methods for preventing a premature ignition of a cylinder charge prior to a planned ignition time in an internal combustion engine.

An advantage of the present invention is the increased safety the pre-ignition prevention sub-system provides to the engine by significantly reducing the likelihood that fuel/air mixture within a cylinder will be ignited prematurely.

SN Plus and low speed pre-ignitionUncontrolled combustion that takes place in the combustion chamber prior to spark in gasoline direct injection (GDI) engines.

This is one of the key elements in preventing pre-ignition, knocking and ring-sticking, but eventually also achieves better performance when controlling oil consumption over time.
