The exhaust system prototypes have been tested focusing on the engine brake performance and on the exhaust temperatures during warm-up transients.
The objective of this collaborative government, academic, and industry research program is to develop the necessary data to assess and characterize in a timely manner (i.e., in the 2007 2008 timeframe) the emissions and any potential health effects from real-world exposures to exhaust from advanced prototype 2007 2010 heavy-duty engines, after-treatment systems, and reformulated fuels.
Thereto, a simple shell and tube exhaust gas heat exchanger prototype generating super-critical or saturated sub-critical refrigerant R134a was experimentally investigated.
Forschungszentrum Karlsruhe (FZK) is developing the ITER prototype torus exhaust pumping system, comprising eight identical cryosorption pumps to provide a high pumping speed and capacity, and fast regeneration.
The cold-start of a prototype diesel engine exhaust aftertreatment system was analyzed using a simplified energy balance to study the impact of system design changes on the performance of the selective catalytic NOx reduction reactor.
A 1 1 prototype of the torus exhaust cryo-pump is going to be manufactured and extensively tested.
In this research, we designed and developed a prototype of a novel diesel exhaust control device: the Electrostatic Screen Battery for Emissions Control (ESBEC).
The behavior of RFC is studied under typical transient conditions of DDF engine exhaust using mathematical modeling and experiments with converter prototype.
There are no thermoelectric generators on car exhausts, although a few prototypes have been built and tested in the past, he says.
In contrast, current prototypes -- a rectangular box surrounding an exhaust pipe, under the vehicle's floor ahead of the rear axle -- are bulky, overweight, costly and produce only several hundred watts depending on the temperature to which they are exposed.
