November 15, 2014: Timer Distribution at the University Center Community Health Fair (8:00AM - 12:00PM).
Municipal residents with engine block heaters installed in their vehicles may come by the Fair to receive a free timer. Timers are used with block heaters to supply electricity two to three hours before the moring commute to improve air quality and save electricity.
Winter car care and driving tips
- Travel ready: you and your family may jump into a warm car dressed for work or school. But in the event of a breakdown or crash, you could spend a long period of time without heat. Wear warm clothes and boots and carry extra in the trunk.
- Tire pressure is likely to drop when outdoor temperatures cool. 'Low' tires wear faster, decrease fuel mileage and are prone to flats. Correct tire pressure is vital for safe vehicle handling and long tire life. If you are adding air to your tires, avoid moisture from gathering in the tire valve where it can freeze and cause the valve to leak. Environment Canada recommeds letting some air out of each valve and blowing some air from the supply hose before filling tires to avoid adding moisture.
- Start-up is a period of maximum engine wear and minimum fuel efficiency for cold engines. Emissions control equipment is very effective for warm engines but not useful until components have warmed. A cold engine produces 50-100 times more pollution in the first minute after starting than one minute fully warmed.

Why Plug at 20 degrees?
To Reduce Engine Wear
Start-up is a period of maximum engine wear and minimum fuel efficiency. Cold oil circulates slowly, leaving engine components unprotected. Block heaters pre-heat engines, allowing them to reach operating temperature sooner and get lubrication to the moving parts. Heat is also available for cabs and windshields sooner - benefiting drivers.
To Reduce Air Pollution
A study performed by Sierra Research in Anchorage and Fairbanks compared emissions from vehicles at cold temperatures. The local testing established that use of block heaters substantially reduced start-up emissions and fuel consumption.
To keep your neighborhood clean
On days with inversions and still air, pollution from vehicle cold starts and idling disperses very slowly. Some of the highest CO levels in Anchorage are found during the morning hours in neighborhoods where traffic is low but many cars are started cold after parking outside overnight. The encouragement to “Plug @ 20” is a reminder to plug even when vehicles start with relative ease.Engine Block Heaters

How long have block heaters been around? Are they used outside of Alaska?
Yes, block heaters were invented by Andrew Freeman, who was born in North Dakota in 1909. To allow their Model A Ford to start, Freeman's family first heated their garage by woodstove to warm the car. The town's mail carrier drained oil from his engine after completing his route, kept it indoors overnight, and replaced it each morning. Other neighbors poured hot water over their intake manifolds or shoveled coals from the furnace onto the ground beneath their engines (yikes!). Freeman received a degree in electrical engineering in 1932, and made application of his skills by cobbling together the heating element from a clothes iron with coiled copper tubing. After successfully starting at 29 below zero, friends and neighbors pleaded for heaters. The 'Freeman Electric Internal-Combustion Engine Head Bolt Heater' received a patent in 1949, and nearly a quarter million were sold in 28 states within four years.

How else can I improve air quality?
- Don’t be an SOV (single occupancy vehicle)! For free, confidential rideshare matching for carpool or vanpool, call the Share-A-Ride program at 562-7665 or register to find your carpool partner online at http://www.peoplemover.org/.
- Forget the window scraping and slippery streets; take the bus to work or use it for errands during the day and keep your parking place.Visit http://www.peoplemover.org/ for your travel choices. People Mover's "Bus Tracker" allows you to view nearly to the minute where the bus is on each route via computer or smartphone.
- Minimize the number of cold starts you make by ‘linking’ your trips. Combining errands can reduce your travel miles and cold start pollution.
- Maintain your car for better startability, mileage, emissions and wear.
- Businesses, organizations and schools can work toward a Green Star Award by reducing solid waste, energy and air emissions from travel and operations. See http://www.greenstarinc.org/.
