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

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

Hydrogen fuels Wankel range extenders

“We originally thought solar cells would be standard on the airplane’s wings,” says George E. Bye, founder and CEO of Bye Aerospace Bye. “However, with eFlyer’s primary markets being flight training and air taxi services, it makes more sense to make the price of the airplane as reasonable as possible.”

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.

After taking off on July 11 in Arizona, the Zephyr S unmanned aircraft from Airbus Defence and Space logged a maiden flight of over 25 days – the longest-duration flight ever made without refueling.

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

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

Environmental test chamber manufacturers such as Weiss Technik are working to meet future refrigerant regulations

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

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

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.

Fiat Chrysler Automobiles (FCE) Canada Inc.; Ford Motor Company of Canada, Limited; and General Motors of Canada Company are stating the need to continue to align with a single national standard with the United States.

While GAC member companies have led the industry in introducing alternative propulsion technologies to reduce greenhouse gas emissions and the GAC supports “de-carbonizing” transportation, the organization says that there has been no modelling done to gauge the impact on the Canadian automotive sector.

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.

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.

General Motors’ electrified, autonomous vehicle future is about to hit overdrive—with related industry standards playing a vital role in the transformation.

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.
