Heat Exchanger Warms Up Vehicles Fast

Heat Exchanger Warms Up Vehicles Fast PICKUPS Accessories 22-3-17 If it seems like it takes forever for the heater in your pickup, car or minivan to warm on cold days, you'll want to check out Easton Bennett's new heat exchanger that'll cut the process down to a few minutes. It's such a hot idea, Bennett has received interest from the Chrysler Corp. "It can be used on any engine," says Bennett of Edmonton, Alberta. "The engine coolant goes into the heat exchanger, then into the heater core, rather than directly to the heater core. The heat exchanger uses hot exhaust gases, which reach several hundred degrees right after ignition, to heat the cool-ant. The result is that it cuts warm-up times by up to 60 percent on even a 20-degree be-low zero day." The heat exchanger kit consists of a section of exhaust pipe with stainless steel tubing wrapped tightly around it. Tests conducted by the Alberta Research Council and Ottawa's National Research Council indicate that the device significantly reduces harmful emissions. On a dynamometer at 20 below C, it reduced carbon monoxide by 8 percent, oxides of nitrogen 12 percent, and hydrocarbons 2.74 percent. The exchanger will also likely improve fuel efficiency since engines use more gas when they're cold than when they're hot, he says. Five units are now installed on vehicles and Bennett is gearing up for full production. Sells for $80 (Canadian).
