The Eaton Energy Solutions Solutions Company announced that it will provide components for the production of trucks participating in the SuperTruck II US Department of Energy.
SuperTruck II is a partnership program between the US Department of Energy, truck manufacturers and equipment providers whose goal is to increase the efficiency of road trains by more than 100% and increase their thermal efficiency by braking by 55% compared to 2009. The $ 100 million program is funded by the US Department of Energy’s Bureau of Automotive Technologies and industry partners.
Eaton supplies original equipment manufacturers (OEMs) with a number of cutting-edge technologies for fuel economy and emission reductions. These include a high-performance gearbox, which provides fuel economy due to engine run-off and recovery of exhaust heat; The 48-volt hybrid electric regenerative braking electric motor, which charges the car’s batteries, provides energy for air conditioning and other accessories, and acts as a generator in trucks carrying the main transport; Exact exhaust gas recirculation controllers, which allow simultaneously to reduce fuel consumption and emissions.
“This is a great opportunity for Eaton’s technology to contribute to the program to improve the efficiency of motor trains,” says Mihai Dorobantu, director of technological planning and communications with government agencies at the Eaton Motor Transport Unit. “We are happy to cooperate with the original equipment manufacturers involved in the SuperTruck II, and we strive to achieve the common goal of creating more environmentally friendly and economical trucks.”
SuperTruck II is a continuation of the SuperTruck initiative by the US Department of Energy, which was launched in 2010 to increase the efficiency of freight trains by 50%. The long-term goal of the project is to develop a technology for creating more environmentally friendly and efficient heavy duty trucks. Such trucks carry 80% of all cargoes in the US and spend about 28 billion gallons of fuel per year, which is about 22% of the total energy consumption of transport.
In addition to the products that Eaton supplies to SuperTruck professionals, the company offers truck manufacturers technology for fuel economy and emission reductions.
“Since 2008, the Eaton Motor Vehicle Company has been focusing on emission reductions and fuel consumption,” Dorobant said. “We have been developing and continuing to develop technologies that reduce the emissions of nitrogen oxides and increase the overall fuel efficiency of diesel engines, as well as technologies for electric, hybrid and engine-powered fuel cells for commercial vehicles.”
Some products use Eaton’s adjustable valve technology, which allows OEMs to choose technology to meet their needs.
The Eaton Motor Vehicle Division offers, among other things, diesel deactivation technologies (CDAs) and control valves (VVA). Both technologies can be used to reduce fuel consumption by 5-25%, increase the speed of exhaust gases and maintain higher temperatures during engine operation. CDA and VVA technologies can also be used for propulsion to achieve active diesel regeneration (DPF) without the use of the traditional method of dosing catalytic oxidation of diesel fuel.
Eaton CDA technology can work at 3-4 bar of braking power at all speeds, which reduces emissions through improved thermal regulation of exhaust gases, while saving fuel. Similarly, the modulation of the inlet valve can be applied at higher loads, which allows to increase the fuel efficiency of the engine when using the Miller cycle.
Another regulatory compliance technology is the Eaton TVS EGR pump designed to save fuel while complying with current international emission standards.
Replacing the TVS EGR pump from Eaton allows you to use high-performance turbomachines to reduce pumping losses and fuel economy. The TVS EGR pump is powered by a 48-volt electric motor, which makes it independent of engine speed and more manageable compared to other EGR systems without pumps.
In addition, the new Eaton decompression motor brake can help OEM engine manufacturers comply with regulatory requirements. The regulation of fuel consumption and emissions reduces the size and speed of commercial vehicles, which makes it necessary to increase the efficiency of braking at lower speeds.
