Highest dynamic compression for pump gas
The biggest limiting factor when attempting to increase compression ratio is the threat of detonation. This is defined as uncontrolled combustion that occurs after the spark plug has fired. Think of the combustion process not as an explosion, but rather, more like a brush fire burning across a large field of dry grass. In an … Ver mais When we talk about compression, this should be more accurately defined as static compression ratio. This is literally the ratio of the … Ver mais Of course, too much ignition timing can cause other problems. For modern engines, a three-dimensional timing map based on both load and RPM will go a long way toward controlling detonation. All engines can benefit … Ver mais Some may be concerned about the iron heads, as there is a concern with enthusiasts that iron heads are more detonation prone than aluminum heads. We actually … Ver mais This effect can be moderated by other atmospheric conditions.
