Abstract
System and methods for operating a vehicle that includes a boosted engine are described. In one example, a spark plug may be adjusted between two operating states to reduce a possibility of pre-ignition and spark plug fouling. A first operating state may be conducive to operating the engine at light loads. The first operating state may be conducive to operating the engine at higher loads.
Claims7
An engine operating method, comprising:
- operating an engine with a spark plug in a first heat dispersal state during engine operating conditions when an engine load is expected to be less than a threshold load, wherein the first heat dispersal state is produced via a biasing device applying a force between a metallic body of the spark plug and a ceramic insulator of the spark plug;
- and
- operating the engine with the spark plug in a second heat dispersal state during engine operating conditions when the engine load is expected to be greater than the threshold load.
