Lewis Hamilton, the reigning world champion Formula One racer, dominated the Monaco Grand Prix on May 24, performing flawlessly until a lapse in data transmission and its interpretation by the Mercedes AMG Petronas technical team cost him the victory.
A second coolant loop in a Fiat Grande Punto prototype provides liquid cooling of the A/C condenser and turbo intercooler, with potential for including air coolers for engine and transmission oil, power steering fluid and other heat exchangers. Engineers measured a 5% improvement in fuel economy during A/C-on operation during NEDC testing.
Connected vehicles bring many of the benefits gained with Internet access, but they also bring security issues including the threat of cyber attacks. That’s forcing design teams throughout the automotive supply chain to focus on a broad range of security technologies that create a holistic defense strategy. Defense in depth is the watchword.
RKLAB AG is developing a self-pressurizing fuel injector that uses an electro-hydraulic multiplier to magnify pressure, and high speed, high flow valving to control fuel delivery. It is designed to provide the potential to reduce engine out emissions sufficiently to eliminate the need for aftertreatment.
The mobility industry is encouraged to get on board quickly and work with other sectors toward common solutions related to the Internet of Things including increasing vehicle safety and reliability, improving the user experience, and exposing new revenue streams for manufacturers and service providers.
A custom tractor-trailer technology demonstrator built by Alcoa is outfitted with various current and “soon-to-be-available” aluminum solutions that altogether can reduce the weight of a tractor-trailer by up to 2500 lb (1135 kg) compared to traditional steel components.
Using the benchmark Alpha mixed-materials architecture that it pioneered on Cadillac ATS, GM takes over 200 lb out of the admittedly overweight 2015 Camaro and adds its first turbocharged four-cylinder powertrain.
A tire pressure monitoring chipset can help fleet managers improve fuel economy and tell when vehicles are overloaded while also simplifying setup times. The Freescale Semiconductor device is said to be the industry’s smallest sensor, yet it has a broad operating range of 100-1500 kPa, exceeding the levels normally required for heavy commercial trucks.
The newly named Johnson Controls Vehicle Engineering Laboratory, on the Lawrence Technological University campus in Michigan, will serve the energy-storage-system supplier and benefit LTU engineering students.
