Any time you compress air it’s going to increase in temperature, with a turbo charger it’s no different. The more boost you run the more heat is imparted to the air going into the engine. This heat along with latent heat from the previous combustion cycle can increase enough that the fuel can actually ignite before the spark plug lights it off, which is called pre-ignition or ping. Pre-ignition can be very damaging to an engine if it is severe enough or occurs over a long enough period of time. So higher octane fuels help avoid this.
The ignition coils used on most cars today haven’t changed all that much in the last 50 years. A simple set of windings that when provided electricity creates a magnetic field that when collapses is amplified and creates enough voltage potential that it can jump a gap between two points. For our purpose with this article that’s as far as we’ll go with the understanding of transformer (ignition coil) fundamentals. Let’s instead focus on the bigger picture as it relates to misfires, specifically those that occur from increase boost and power development.
Ignition Won’t Turn Past Position I https://www.matthewsvolvosite.com/forums/viewtopic.php?p=97472#p97472 Having removed the plastic covers and electric bits away from the area, I chiseled off the metal plate at the bottom of the lock. I found a broken piece of casting inside but the guillotine would still not move down. With the chisel and a pair of cutters, […]
