Thermostatic Air Cleaner: Description and Operation
Thermostatic Air Cleaner
This system, Fig. 16, takes hot air from near the exhaust to warm up the intake air during cold weather operation. Warming the intake air produces
better fuel atomization and improved driveability during warm-up, and while driving in very cold weather.
