elvin, 如文中所做的測試, 較大的ignition energy是不會對flame propagation有改變, 只會有更惡劣的點火環境下更有利於將air-fuel mixture成功點燃.
而惡劣的點火環境即是air-fuel mixture混合得唔夠homogenous or 溫度低 or loading大時.
所以, 改用一個勁力的ignition coil應有百利而無一害...唔計火咀蝕快左啦.作者: coupeelvin 時間: 2010-3-25 10:00
I just wonder such increased ignition power will affect the ignition timing.... The case may be similar to choosing wrong spark plugs of wrong gaps... I don't know if increasing the ignition power would really mean good at all times.
But one thing for sure, if our 20V turbo wants to increase the ignition power, we can either change the Coil-on-plug modules (if available) to aftermarket ones from MSD for example, or add a boosted voltage supply (up to 14.5V) to these modules. Such boosted supply must be isolated from the battery supply... The latter option seems viable at this moment with limited cost, but the lifetime of the modules will surely be shortened.
