The pre-ignition in ic engine may be due to
Webb14 jan. 2014 · Pre- Ignition In SI engine the combustion during the normal working is initiated by a electric spark. The spark is timed to occur at a definite point just before the end of the compression stroke. The ignition of the charge should not occurs before the spark is introduced in the cylinder, if the ignition start due to any other reasons when the ... WebbWhen the engine runs at the maximum brake torque condition, an early ignition will increase the NOx emissions because more time would be available for combustion. Retarded ignition timing from maximum brake torque would increase the exhaust temperature and also the better postflame characteristics.
