we change the detonation sensor of gas engine but the detonation alarms not vanished he shows alarm on previous routinee tell me what causes of this problem?
Dear,
Please to inform you that your air filter is not properly clean on daily basis or wekly your invoirment is dusty and premature iginition is cause of detonation take prompt action for rectified this problem for safe heavy loss if you find valve gutring and piston failure you investigate properly for reprogram your snesors through by pass one by one and replace if you found any sensor faulty if you found your all sensors work properly so arrange T.A -II Test and inspect your Cylinder Head with Bore Skoping properly for safe any heavy loss or equipments it is not normal situation it is very harmfull to our engine so don't avoid and take serious and contact your Dealer for rectefied propely.
All you need to do is play a little with ignition timing. Air / fuel ratio comes second but the factor that you can easily change is timing. Maybe a little retard timing would help as system is being pre-Ignited. So the delay would prevent it.
Detonation is affected by many things including timing, compression ratio (or boost), RPMs,
when at high loads and low RPMsWater methanol injection can drastically reduce detonation by cooling the chamber as well as adding octane.
