Effects of Spark Advance on Emissions and Driveability

• Too much spark advance, particularly during high engine load conditions, increases the likelihood of engine detonation and increases combustion temperature and pressure. This results in an increase in HC and NOx output, decreased engine performance, and possible permanent damage the engine.

• Too little spark advance causes only partial combustion of the air/ fuel charge, resulting in very poor engine performance and fuel economy. Partial combustion will also result in an increase in CO levels.
