Two new installments in the burgeoning SAE International Podcast Series cast a spotlight on additive manufacturing, which is fueling innovation, greater efficiencies, and the future of mobility engineering. Additive manufacturing continues to advance and transform mobility engineering, as aerospace and automotive firms increasingly adopt and invest in 3D printing technologies, which are becoming more capable and cost-effective.

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.

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

Commercial vehicles are beginning to adopt alternative energy sources, but the transition remains slow. Batteries and an array of renewable fuels are seeing more usage, but costs and infrastructure remain hindrances for these fragmented technologies.

Alternative fuels and propulsion poised for growth in US fleets

Various levels of electrification, connected solutions and alternative fuels are among the technology pathways that will lead to reductions of CO2, according to AVL's Dr. Marko Dekena. He spoke with Truck & Off-Highway Engineering about a variety of topics ahead of this year's AVL International Commercial Powertrain Conference.

FPT Industrial offers a broad range of natural gas engines, with solutions from 136 to 400 hp (101 to 298 kW) for light, medium, and heavy vehicles. The brand is also in the advanced stages of trialing natural gas engines for agricultural equipment, says brand president Annalisa Stupenengo.

Arctic vehicle automation

BorgWarner Chief Technology Officer, Christopher P. Thomas, discusses the company's new exhaust gas recirculation modules, EcoFlash ignition system, and heavy-duty controlled coolant pump for commercial diesel and natural gas engines, as well as the trends driving their development.

At the convergence of 3D-printing and lithium battery technology, Hong Kong researchers develop a promising textile-based, foldable battery that may find its way onto IoT-connected fabrics within automotive, aerospace, and medical industries.

China’s commercial-vehicles industry is poised for a transformation as suppliers focus on services and clean energy. These changes are occurring amid market shifts as China attempts to reduce pollution and congestion in cities.

The Proterra Catalyst all-electric transit bus nabs double-digit miles per gallon equivalent (MPGe), vastly outperforming its diesel, compressed natural gas, and diesel hybrid-electric rivals.

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 Energy Department recently awarded Cummins, the nation’s only independent diesel engine maker, a two-year, $4.5-million grant to boost its previous mark by 5 percentage points to 55% brake thermal efficiency.

The Class 8 demonstrator notched 10.7 mpg with a fully loaded tractor-trailer, representing a 75% fuel-economy increase and a 43% greenhouse gas (GHG) emissions reduction compared to a 2009 baseline truck.

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

FEV researchers conducted a study to understand the challenges of downsizing a diesel engine from a six-cylinder 7.5-L to a four-cylinder 5.0-L while maintaining performance. They pursued four technology paths.

EOS StainlessSteel CX, EOS Aluminium AlF357, EOS Titanium Ti64 Grade 5, and EOS Titanium Ti64 Grade 23 have been tailored to suit a broad array of applications, ranging from automotive, medical, and aerospace applications.

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.
