Hydraulics still in control of off-highway needs Engineers continue to master electronic controllers and software to help systems manage engine speeds and boost efficiency, to the ultimate benefit of both OEMs and end-users.
Off-highway calibration challenges—big and complex As the final set of Tier 4 regulations kick in for engines greater than 750 hp (560 kW), calibration efforts must contend with complex engine and aftertreatment systems. Engine manufacturers and service providers deal with this complexity, but does it need to be so?
DEF delivery modelling for SCR systems Researchers characterize a 0-D model of a urea delivery module, oriented to model-based control and to the simulation of the system response to fault injections finalized to diagnosis validation.
Development trends for heavy engines Downsizing engine displacement, new materials, friction reduction, and advanced boosting and fuel-injection technologies have demonstrated potential in light-duty vehicles, and implementation is under way. FEV experts provide an outlook of how these technologies can improve the base engine for commercial applications with regard to future emissions and fuel-efficiency requirements.
GM’s CTO driving new paths to technology leadership 'We’re making actual production commitments regarding our advanced-technology strategy, rather than just talking about it,' says GM’s CTO Jon Lauckner. 'We’re absolutely going to be among the leaders, if not the leader, in these areas.'
Aluminum prepares for its next big leap Ford’s F-Series blockbuster was just the beginning. New micromills now in pilot phase aim to bring vastly stronger and more formable light-alloy materials at higher capacity, says Alcoa’s Mike Murphy.
Slick solutions for friction reduction From new lubricants to ‘smart’ oil pumps and clever bearing technologies, engine designers are attacking every potential source of spin losses and internal friction in the quest for more mechanical work out of less fuel.
Next-gen NSX: a twin-turbo, multi-material Ferrari-fighter The production NSX made its much-awaited global debut at NAIAS in January. More technical details of Acura’s mid-engine AWD hybrid supercar will be shared by Honda R&D experts at the SAE 2015 World Congress.
Deep thinking about deep space NASA is mining the rich fields of knowledge and creativity in the minds of university students to improve living and working conditions in space.
Rise of the underdogs Problem-plagued effort last year spurs Baja SAE team from VIT University of India to overhaul itself and its car.
Materials, data-aq packages among choices touted in Collegiate Cup contest Central Michigan’s Baja team, which did some impressive materials analyses, takes home the SAE Mid-Michigan Section’s trophy as part of that professional group’s Engineers Week activities.
Toyota looks for more from college students than high GPA "Those that participate in an SAE related-activity display passion for the automotive industry, and these candidates are ideal for our organization."
Next-generation GDI Will new efficiency and emissions rules mean major changes for gasoline direct-injection technology?
Hard to answer Technical and personal issues make it challenging to link smartphones to vehicles.
Composite design optimization for automated fiber placement Coriolis Composites and SAFRAN Aircelle worked together on a thrust reverser component demonstrator made with carbon-fiber-reinforced plastic (CFRP) material and an AFP process.
Making virtual design a reality A new virtual design approach for commercial vehicle concepts allows for purposeful design and integration of new concepts and technologies on the component level in an existing product portfolio, while not neglecting the need for standardization and modularity.
