The four-year Clean High-Efficiency Diesel Engine (CHEDE) program is using a variety of new technologies and research findings to progress to a super-efficient, low-emitting heavy-duty diesel engine system with 55% brake thermal efficiency.

The challenges of climate change and energy security require a continuous effort toward reduction of global environmental pollution and fossil oil consumption. To meet greenhouse gas (GHG) emission targets and to decrease oil dependency, overall energy consumption of vehicles must be substantially reduced.

In March, a new demonstrator engine by Rolls-Royce, featuring a cutting-edge lean-burn and low-emissions combustion system for future jet engine programs, began icing tests at the Global Aerospace Centre for Icing and Environmental Research in Manitoba, Canada.

SAE International has published a new recommended practice for assessing the amount of nonvolatile particulate matter (nvPM) that exits aircraft engine exhaust nozzles – ARP6481: Procedure for the Calculation of Non-Volatile Particulate Matter Sampling and Measurement System Losses and System Loss Correction Factors

Technology transfer and collaboration continue to grow globally among mobility engineering professionals focused on aerospace and automotive applications. Cross-industry partnerships received a boost this week, as Japan Aerospace Exploration Agency (JAXA) and Toyota Motor Corp. officials announced increased cooperation on unmanned, electrified, and automated rovers for space exploration.

Engineers at Boeing and NASA are collaborating on a lightweight, ultra-thin Transonic Truss-Braced Wing (TTBW) concept, designed to be more aerodynamic and fuel efficient than current designs, as part of the Subsonic Ultra Green Aircraft Research (SUGAR) program focusing on innovative aerospace concepts that reduce noise and emissions while enhancing performance.

Established on July 1, the ECLAIR consortium will focus on reducing greenhouse gas emissions and other negative environmental impacts of the aerospace industry by developing innovative electric technologies.

In reviewing Obama-era vehicle-emissions standards dictated aggressive fuel-economy standards for the years 2022-2025, the U.S. EPA said that in light of current market conditions and consumer preferences, the regulations should be revised.

Standards development teams at SAE International in Warrendale, Pa., have issued 11 new technical documents and revised or reaffirmed another 54 technical reports focused on mobility engineering across the aerospace, automotive, and commercial transportation communities. The new documents, issued throughout June 2018, cover a variety of technical subject areas, including: diagnostic link connector security, mitigation strategies against illumination effects, data dictionary for quantities used in cyber physical exams, requirements for production of metal powder feedstock for use in additive manufacturing of aerospace parts, and laser powder bed fusion process.

Looking beyond EVs at other systems that can garner net-zero capabilities.

Weber Metals Inc., a division of Otto Fuchs KG of Germany, unveiled a new, $180 million, 60,000-ton press at its 2.5-acre facility in Paramount, California, southeast of Los Angeles. It sets a record as the highest tonnage hydraulic forging press in the Americas and the largest privately funded forging press investment in the world.

The U.S. light-vehicle fleet will need to more-aggressively adopt fuel-saving technologies if it is to comply with pending efficiency regulations.

As global emissions regulations tighten, the automotive and marine sectors lean into alternative-fuel development.

SAE International, a global association committed to being the ultimate knowledge source for mobility engineering, is bringing together subject-matter experts from across the globe for the first SAE International Aerospace Japan Symposium, held November 29 and 30 in conjunction with Japan International Aerospace Exhibition 2018 at Tokyo Big Sight convention center in Tokyo.

The strategy identifies 2025 as a target year to collaborate with communities around the globe and create products focused on environmental performance, emissions and waste reduction, and lower levels of water and energy consumption at work sites.

Medium-duty demonstrator intended for the North American market will feature a Cummins PowerDrive6000 drive unit mated to an Isuzu’s F-Series chassis.

The aerospace industry is facing immense challenges due to increased design complexity and higher levels of integration, particularly in the electrification of aircraft. These challenges can easily impact program cost and product time to market. System electrification and electromagnetic compatibility (EMC) have become critical issues today. In the context of 3D electromagnetics, EMC electromagnetic compatibility ensures the original equipment manufacturer (OEM) that radiated emissions from various electronic devices, such as avionics or the entire aircraft for that matter, do not interfere with other electronic products onboard the aircraft.

Diesel engines continue to evolve to stay relevant while the industry intensifies its pursuit of zero emissions
