Cummins progressing with lightweight downsized T2B2 diesel for pickup; 40% improvement in fuel economy over gasoline V8

Green Car Congress

At the US Department of Energy’s (DOE’s) Annual Merit Review meeting in Washington, DC last week, Michael Ruth from Cummins noted that the DOE program target for the project is a fuel economy (CAFE) target of 26 mpg (9.05 Earlier post.). l/100 km), and as such would not meet the GHG requirement of 28 mpg (8.4

Google and IEEE launch $1M challenge for downsized inverters

Green Car Congress

We believe that inverters will become increasingly important to our economy and environment as solar PV, batteries, and similar power sources continue their rapid growth. For example, GM is leading a DOE funded project for a next-generation inverter targeting improving costs to $3.30/kW

ICCT working paper highlights benefits of current and emerging light-duty diesel technology; “promising pathway for compliance”

Green Car Congress

The ICCT team—John German and Aaron Isenstadt—concluded that diesels have and will retain two significant advantages over gasoline engines: significantly better fuel economy and cargo hauling and towing ability. Meeting the 2025 standard will require an average improvement in fuel economy of about 4.1% Background.

MECA report finds additional NOx emission reductions from new heavy-duty trucks achievable and cost-effective

Green Car Congress

Manufacturers continue to optimize diesel emission controls, such as DOC, DPF and SCR, in order to promote uniform catalyst coating, improve NO x conversion efficiency, reduce back pressure on the engine, and reduce thermal mass. Better catalysts and urea dosing systems can achieve high NOx conversion during lower temperature operation.

Simulation study suggests ORC waste heat recovery system could deliver potential 7% improvement in fuel consumption in a PHEV on highway

Green Car Congress

The analysis used the Ohio State University EcoCAR, a student prototype PHEV, as the basis for the preliminary fuel economy evaluation. Internal combustion engines have been significantly improving in the past decade, after the adoption of technologies such as Gasoline Direct Injection, mild electrification, downsizing and turbocharging.

Independent testing shows 21.2% reduction in fuel consumption with XL Hybrids retrofit system

Green Car Congress

The testing process compares fuel economy performance from the vehicle in its original condition with the performance using XL Hybrids’ charge-sustaining hybrid system. XLH engineers have already designed the next-generation release, in which the battery pack is downsized to 1.5 The company had been targeting a 20% reduction.
