Difference between revisions of "Warm air intake"
Latest revision as of 16:44, 8 July 2018
Higher intake charge temperature has been found to increase the flame speed, the combustion reaction rate, the uniformity of the fuel-air mixture and reduce the heat transfer rate though the cylinder walls. This all adds up to the engine using more heat for physical movement and less being wasted.
The downside to this is that hotter air also tends to retard ignition timing and cause engine pinging. Different engines will react differently to warm air intakes and testing will need to be done to see if it will work for your specific vehicle. Saturns are known to react well to warm air intakes.

If your engine temp is too high because of the WAI or the HAI, this could damage it.
Not recomended for diesels unless operated in very cold weather.
