Webb• Thus, the delay in start of ignition may be said to occur due to ‘physical delay’ i.e. time consumed in transformation from liquid droplet into gaseous form, and‘chemical delay’ i.e. time consumed in preparation for setting up of chemical reaction (combustion). • Stages of Combustion in CI Engines (i) Ignition Delay Period Webb15 jan. 2024 · Auto-ignition. Auto-ignition ( sometimes referred to as "detonation") is the spontaneous combustion of the end-gas (remaining fuel/air mixture) in the chamber. It … 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. great job images snoopy
