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.

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.

Viable exhaust-driven on-board ethanol reforming for improvements in fuel economy and emissions

Green Car Congress

A team at Monsanto and colleagues at AVL Powertrain have successfully designed and demonstrated an onboard low-temperature ethanol reformer that can be driven by exhaust heat. Many papers have described high-temperature steam reforming of ethanol at around 600 °C but.this temperature is too high to be driven by engine exhaust.

NRC report finds significant number of near-term technologies could greatly reduce fuel consumption in passenger cars

Green Car Congress

According to its estimates, adopting the full combination of improved technologies in medium and large cars and pickup trucks with spark-ignition engines could reduce fuel consumption by 29% at an additional cost of $2,200 to the consumer. Turbocharging and downsizing can also yield fuel consumption reductions.
