Technical Tidbits: The Technology of a Thermostat

  • Bill Grannis

Current EPA regulations make the thermostat an important component for efficient engine operation and to meet low-emission requirements.  A gasoline-powered engine needs the proper temperature to help vaporize the fuel, to provide for the proper piston to cylinder fit, and to promote complete combustion with low emission output. Thermostats regulate the temperature of the water in the cylinder block and… More
