Single source e-boosting allied to 48V technology for small capacity engines in traffic dense environments could "leapfrog" turbo or turbo plus eboost solutions, believes Aeristech's chard Wall.
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.
Huge factories and technical improvements are slowly pushing battery pack costs down toward the $100/kW·h turning point that's expected to democratize electrified vehicles.
The WI system is in pilot development with a Bosch customer. Test results to date show a reduction of fuel consumption at high loads and low rpm (up to 4% improvement on the NEDC cycle); reduction or avoidance of fuel enrichment and lower exhaust-gas temperatures at high loads and high rpm, and improved torque.
The actual J1349 rating is more than 100 hp more than Chrysler engineers teased in late May. The automaker's first production supercharged V8 uses a Lysholm-type twin-screw supercharger supplied by IHI. The engine's high-output spec required extensive upgrading of engine reciprocating components to handle the extra loads.
Demand for high-performance plastics (HPPs) is up across the aerospace industry, driven by such key trends as growing performance requirements, increased use of additive manufacturing or 3D printing, supply chain globalization, and tightening environmental regulations. Growing passenger traffic coupled with the need to reduce emissions – being accomplished through lightweighting, engine downsizing, and vehicle electrification – present opportunities for HPPs, research analysts at Frost & Sullivan in San Antonio, Texas, explain.
Every vehicle powered by Ultium batteries incorporates efficiency-enhancing energy recovery system based on heat-pump technology covered by 11 patents.
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.
SAE International in Warrendale, Pa., is inviting members of the mobility engineering community to participate in the SAE Additive Manufacturing Webinar: Considerations When Integrating Additive Manufacturing into Aerospace and Ground Vehicle Development and Production Environments on Thursday, August 16, 2018 at 1 pm EDT/10 am PDT.
The big challenge for Dirk Hacker's engineers was to retain the rear-drive feeling that the M5 is known for; "we want the driver to feel that he can steer the car on the throttle as well as with the steering wheel,” he explained.
Four of these technologies – smart coatings for corrosion detection and protection, aluminum alloys for high temperature applications, particle contamination mitigation technologies, and thermal and environmental barrier coating systems – are among NASA’s most in-demand technologies and have been applied to mainstream engineering projects.
After 2020 the number of ‘new’ engine family introductions will decline, as industry switches its investment over to e-propulsion. Suppliers need to be prepared for this shift.
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
It isn’t every car maker that introduces you to your new car with a session on a tight and slippery test track - but it's useful education for exploiting the capabilities of the hugely powerful Mercedes-AMG E 63 S 4Matic+.
