Webb12 feb. 2016 · Most recent answer. Compared to SI engines knocking in CI engines have less occurrence. This is due to time delay or ignition delay. Detonation is a kind of … WebbTherefore, there is no question of pre-ignition occurring in the CI engine, whereas pre-ignition may occur in the SI engine due to the presence of both fuel and air during compression. (d) In the SI engine, knocking can easily be detected by human ear but in the CI engine there is no clear distinction between knocking and normal combustion, since …
Webb13 okt. 2015 · IC engine kicks in when additional power is needed like during acceleration *Supercharger and TurbochargerThese devices are used to increase the power of an IC engine by raisingthe intake pressure and thus allowing more fuel to be burned per cycle. Knock or autoignition phenomenon limits the amount of precompression. 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.
