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

Green Car Congress

Cost of the new engine relative to gasoline baseline. So far, Ruth noted, the new engine has achieved target engine-out emissions (EOE), performance and fuel economy; aftertreatment catalyst performance has met or exceeded the targeted conversion rates, enabling an increased allowance on engine out HC.

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.

ALABC: 48V mild hybrids can meet emission targets with CO2 reductions of 15-20%

Green Car Congress

The T-Hybrid (based on a Kia Optima) ( earlier post ) and the ADEPT (based on a Ford Focus) ( earlier post ) both utilize an advanced 48V lead-carbon battery system with bolt-on electrical components that allow for significant engine-downsizing without loss in performance. liter engine the performance of a 1.8

Study finds that aluminum reduces electric vehicle cost against steel counterpart for same targeted range

Green Car Congress

A recent study found that an aluminum electric vehicle can cost up to €635 (US$829) less than that its steel counterpart despite the higher cost of aluminum, given equivalent range targets. The next step was the conversion of that EV to a full aluminium space frame electric vehicle.

MECA report assesses technology feasibility for heavy-duty diesel trucks to meet lower NOx standards by 2024

Green Car Congress

The main conclusions in the report include: Several advanced technology options can be deployed on heavy-duty engines and vehicles to reduce NO x emissions by 75% below today’s heavy-duty FTP NO x standards while also meeting the 2024 heavy-duty Phase 2 greenhouse gas limits and reducing the total cost of ownership of trucks.

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

Green Car Congress

Diesel vehicles have had a rough time penetrating the US light-duty vehicle market, reflecting outdated negative perceptions, higher fuel prices for diesel than for gasoline, the cost of complying with stringent US emission standards, and rapidly improving gasoline engines. E-boost and 48V.
