DOE awards $1.5M to Gentherm (Amerigon) for thermoelectric-based energy recovery system for heavy-duty vehicles; expands existing LDV program

Green Car Congress

The TEG technology, which converts waste heat from gas exhaust into electric energy and has the potential to improve passenger car fuel efficiency by as much as 5%. TEG & Exhaust System in Lincoln MKT. The US Department of Energy (DOE) has awarded Gentherm (formerly Amerigon) a $1.55-million Click to enlarge.

Small-displacement two-stroke H2 engine could address performance and emissions cost-effectively for recreational market; potential for Asian motor vehicle fleet

Green Car Congress

This is due to raw, externally premixed fresh charge comprising air, fuel and lube oil being short-circuited into the exhaust during the scavenging process. Even with the move to four-stroke engines, additional complexity will be necessary—possibly exhaust after-treatment—in order to fully meet regulations.

EPA Proposes to Streamline Approval Process for Fuel Conversion Systems

Green Car Congress

Conversion systems allow vehicles to run on alternative fuels; most conversions involve switching gasoline or diesel vehicles to operate instead on a gaseous fuel such as natural gas or propane; an alcohol fuel; or electricity. EPA expects the streamlined approach to result in a cost savings for many converters. Intermediate age.

BMW Outlines Intelligent Heat Management Applications for Reducing Fuel Consumption and CO2; New Thermoelectric Generator Unit Integrated with EGR

Green Car Congress

Even a highly efficient combustion engine converts only about one-third of the energy in the fuel into traction actually propelling the car. The remaining two-thirds are lost as waste heat going into the environment through the car’s exhaust emissions and through the radiator.

Norway-US Project Developing Diesel/Biodiesel, Cool Flame Reformer and Solid-Acid Fuel Cell APU

Green Car Congress

The reformer converts hydrocarbons into hydrogen, CO 2 and heat. Due to the unit’s high efficiency, CO 2 emissions are substantially lower than in conventional combustion engines, and no other demonstrable exhaust is discharged—i.e., This allows SAFCell stacks to run more easily on commercially available gas fuels (e.g.,

Toyota Previews Generation III 2010 Prius Hybrid

Green Car Congress

The complex engine coolant heat storage system utilized by the Gen II Prius has been replaced by an exhaust heat recirculation system that shuttles catalyst heat to a heat exchanger which interfaces with the engine cooling system, reducing engine-on time and improving cabin heater system performance.

from engine exhaust or industrial processes. Thermionic energy converters are heat engines that convert heat directly to electricity at very high temperatures. A basic thermionic converter consists of two electrodes separated by a vacuum or a vapor. Thermionic emission and TICs. Click to enlarge. W/cm 2 at 26.6%
