The Rochester (MN) Fire Department Monday afternoon showed off its two new apparatus—Truck 42 and Engine 5—which feature new idle reduction technology that officials say will reduce fuel usage by an estimated 50% each year, reports kttc.com.
The way the system is designed, officials say, is when the truck is idling the computer takes over and after a certain amount of time, if the battery is fully charged, the engine will shut off automatically. It will run off lithium-ion batteries until it knows it has to recharge.
Truck 42 will replace a truck more than 20 years old, while Engine 5 replaces a 15-year-old truck, the report says.
