Christopher Grundler, the Director of OTAQ for the U.S. EPA, answered questions about Phase 2 rule-making for heavy trucks, global harmonization of emissions regulations, and his outlook for a new national NOx standard. Grundler will be the featured speaker on opening day of the SAE 2017 Government/Industry Meeting taking place January 25-27 in Washington D.C.
London Mayor Sadiq Khan unveiled the world’s first double-decker hydrogen bus at the end of November as part of a commitment to phase out purchase of new pure diesel buses in the capital's fleet beginning in 2018.
UQM Technologies, Eaton and Pi Innovo are developing a full electric drivetrain system to include motor, 2-speed transmission and inverter with transmission control unit for the medium- and heavy-duty EV markets.
Daimler Trucks' Dr. Wilfried Achenbach, who is serving as chairman of the SAE 2016 Commercial Vehicle Engineering Congress, discusses a range of significant technology issues including automated driving, Phase 2 GHG regs, the Industrial Internet of Things, cybersecurity and plans for the SuperTruck.
Powertrain experts detailed the technologies they see as most promising to enable light-vehicle engines to meet global CO2 regulations through 2025, at the 2016 SAE High-Efficiency IC Engines Symposiumt. The list includes growing use of the Miller and Atkinson thermodynamic cycles, cooled EGR, and water injection, as well as variable compression ratio systems, dedicated EGR, and divided exhaust boosting.
Tesla engineers have previously talked about a potential mixed-materials strategy as they move down the retail-price ladder. The prospect of an aluminum-intensive Model 3 raises the question of how profitable a $35,000 EV will be when it carries 60-80% of the battery capacity of the basic $71,200 Model S 70.
Consortium of OEMs and suppliers worked on all fronts, while the SAE Interior Climate Control Committee reopened a suite of draft standards to prepare for possible importation of cars with R-744: CO2 as a refrigerant.
More hydrogen fueling stations in California and additional electric vehicle charging stations across the U.S. could reduce the range anxiety consumers have about driving these advanced-technology vehicles.
Raising the octane level of pump gasoline in the U.S. is integral to optimizing advanced combustion engines now in development, said GM and Honda executives at the 2016 CAR Management Briefing Seminars in Traverse City, MI. Their comments prompted positive but non-committal comments from Chris Grundler, Director of the Office of Transportation and Air Quality for the U.S. EPA.
Stringent fuel-efficiency and criteria-pollutant standards call for new combustion strategies. The Advanced Combustion Catalyst and Aftertreatment Technologies consortium led by Southwest Research Institute reinvents existing technologies and experiments with new catalysts to meet standards.
New Holland is ramping up its focus on vehicles that burn alternative fuels, unveiling the prototype for a methane-powered tractor set for introduction in the 2020 time frame. The engine slashes operating costs, reduces emissions and cuts noise.
Cummins, MTU, and Deutz, among others, offer a preview of the technology they're developing to meet the European Union’s Stage V emissions regulations for off-highway equipment that could commence in 2019.
