Bosch innovations for cv Power from the exhaust tract Fuel saving of up to 5 percent
Date:2012-10-19 Author:Mika Source:www.chinatrucks.com
www.chinatrucks.com: In addition to enhancing already existing technologies such as common-rail injection systems and exhaust-gas treatment systems, Bosch is working on new technologies that improve commercial vehicles’ fuel economy and reduce their emissions even further. They include the recovery of waste heat from the exhaust tract. The WHR waste-heat recovery system, which converts the waste heat in the exhaust tract into electrical or mechanical power that is fed back into the commercial vehicle’s powertrain, offers a potential fuel saving of roughly five percent. This fuel saving means a corresponding reduction in CO2 emissions.
Power generation using an expansion machine
Today, some 60 percent of the primary energy used to power commercial vehicles is lost via the radiator and exhaust as waste heat. The Bosch WHR process uses a steam power cycle. The waste heat in the exhaust is used to generate steam, which drives an expansion machine. The mechanical energy gained as a result can be used to drive the commercial vehicle’s crankshaft, either directly or via a gear unit. Alternatively, a generator can
be driven that supplies electricity to the on-board vehicle network or the hybrid system’s traction battery. The expansion machine is the central component for this energy conversion process. It can be designed as a piston engine or as a turbine. In its development work, Bosch is currently pursuing both options. Depending on vehicle type and total mileage, a WHR system allows up to 2,500 liters of diesel to be saved per year and vehicle.
Maximum efficiency in long-haul traffic
Waste-heat recovery from the exhaust tract is perfect for the powertrains of long-haul heavy trucks. This is because the WHR system achieves its maximum efficiency in long-haul operation, when there are constantly high temperatures in the exhaust tract over considerable periods of time.
It is also fundamentally possible to use the WHR system for off-highway applications. The technology on which it is based is already to be found in stationary machinery. However, one of Bosch engineers’ major development tasks in the years ahead will be to adapt this technology to the tough conditions in the commercial vehicle, and to make it ready for large-scale series production. As has been proved on many occasions in the past, this is one of Bosch’s strengths.
