BorgWarner has launched a website at www.coollogic.borgwarner.com to educate people about the advantages of Cool Logic variable speed fan drives.
According to the company, those include:
· Improved fuel economy of up to 4 percent in city operation and 2 percent in highway operation (depending on route terrain, truck load and duty cycle);
· As much as 60 additional horsepower for more power on grades, less shifting and less driver fatigue;
· 79 percent reduction in temperature extremes and 75 percent less thermal stress on cooling system components;
· Lower fan speeds at idle for greater mileage, less noise and improved driver comfort; and
· Maintenance-free design for fewer service hours and lower costs.
The new website’s 3-D computer-animated graphics illustrate how Cool Logic technology responds to signals from the engine control module hundreds of times per minute. The Cool Logic system electronically varies fan speed and provides consistent, precise temperature control that automatically adjusts to load and road grades, according to the company. Providing continuous variability for a truck engine’s cooling system, the Cool Logic wet-friction clutch design reduces engine drag, delivering more horsepower and greater fuel economy compared with traditional on/off or two-speed clutch systems.
The website also features a mileage calculator fleet owners can use to analyze annual fuel economy savings based on number of trucks, mileage, diesel prices, average mpg and truck use. With the average semi-truck logging 150,000 miles a year, a 2 percent to 4 percent increase in fuel economy can equate to substantial bottom-line savings for fleets operating thousands of trucks. A matrix of truck engine applications, downloadable literature and frequently asked questions are also available on the website.
