According to the U.S. Environmental Protection Agency, fleet trucks travel a total 4.5 trillion vehicle miles annually. A single fleet truck can average 500 miles of driving each day and can be on the job for as many as 26 days in a given month. On average truck drivers spend between 1,800 to 2,400 hours a year idling. The reduction in engine idling alone could save up to 838 million gallons of diesel fuel every year and annually reduce engine emissions equal to that produced by 15.5 million cars. An estimated one gallon of diesel fuel is consumed for every hour a vehicle is at idle. This amounts to about 1 billion gallons of diesel fuel lost as a result of idling. Argonne National Lab work also shows that a truck idling only eight hours can put an estimated 7.6 million tons of carbon dioxide, 140,000 tons of nitrogen oxides, and 2,400 tons of carbon monoxide into our atmosphere. Nextronics’ technology provides an ability to add hybrid technology to any conventional gasoline or diesel engine vehicles. The Nextronics IdleStop™ from is an advanced electronic motor/generator that replaces, and functions as, the vehicle’s alternator/generator under normal driving conditions. Once the brake pedal is pressed, and the vehicle is stopped, the engine shuts down while the IdleStop™, functioning now as a motor, keeps the engine accessories turning. This provides functionality of all vehicle accessory subsystems such as air conditioning, air control systems and electrical systems. When the brake pedal is released, the IdleStop™ immediately starts the engine and then returns to its usual alternator/generator function. The IdleStop™ is the world’s first retrofittable Engine Idle-Off product for the medium and heavy duty truck market that substantially reduces diesel idle emissions and noise, with a slight increase in fuel economy. Nextronics in collaboration with Texas A&M will manufacture and install the IdleStop TM motor/generator to a selected TxDOT low temperature duty cycle vehicle. The Nextronics technology may be applied to any low temperature duty cycle diesel; Nextronics will seek the direction of TCEQ in its selection of the test vehicle. The benefits from utilization of an IdleStop™ system are as follows:
- Traditional hybrid electric vehicle (HEV) emission reductions are expected
- Elimination of up to 93% of harmful exhaust emissions produced during idling
- Increased vehicle maintenance intervals, serviceability, as well as cost reduction
- Increased profitability for fleet owners
- Improved fuel efficiency by as much as 8%
