Additive Manufacturing Utilizing a Novel In-Line Mixing System for Design of Functionally Graded Ceramic Composites Exploring the development of a direct ink writing system with multimaterial and in-line mixing capabilities for printing inks composed of high solids-loaded ceramic particulate suspensions.

Solving the Greenhouse Gas puzzle While automakers and policymakers debate the TAR, engineers and product planners prepare for the steep climb to meet GHG and CAFE rules beyond 2022. Revving up thermal characterization in the component lab The latest generation of high-speed infrared cameras can capture airbag deployments and other fast-moving actions quickly and accurately. C3 consortium aims for soot solution A newly formed group of companies led by CFD specialists Convergent Science targets exhaust particulate reduction in the combustion chamber. Inside the autonomous vehicle With less focus on driver needs, comfort, safety, and occupant productivity will become key. Editorial: Bad gas?

Oil debris monitoring in aero engines In a gas turbine engine, small particles or "chips" are generated at the point of wear, serving as an advanced warning that catastrophic failure will occur if the wear is not addressed. Health monitoring systems, such as oil debris monitoring, are used to find these small particles so that the wear can be resolved before it's too late. Indigenous powertrain development Customer needs and expectations on drivability, fuel economy, and safety has pushed Indian and multinational OEMs to think about the development of powertrains and gearboxes for local needs with global standards. The next wave of crash simulation As computing speed has improved and software itself has made significant speed and performance gains with each release, modeling tools are now quick enough to build high-quality, large, high-detail vehicle models in a very efficient manner.

Steering a better path New mechanisms developed by NIT Warangal are simpler than the Ackermann type and allow all four wheels to undergo pure rolling. Monitoring fine particle concentrations A robust and versatile system has been developed by Pegasor Oy to measure engine exhaust particulate mass and number more accurately. New rules shuffle the F1 deck New turbocharged hybrid-electric power units and revised aerodynamics may scramble the familiar order in Formula One for 2014.

Alternative fuels heat up This is a rich time for combustion researchers. The need for better fuel efficiency and improved emissions has never been greater. New software model to help engine makers meet diesel soot standards Simulation enables engineers to predict particulate formation early in the design process.

Shrinking hydraulics The push to conserve fuel and reduce emissions is prompting major changes in system design. Aftertreatment temperature control Regeneration of a DPF burns off soot, but also raises exhaust gas temperature. Speed thrills: doing more tests in less time Quicker data gathering, simulation keep quality high despite time crunch. Green engineering The quest to alleviate environmental and efficiency pressures turns up 'small' material solutions with big benefits. A global forum Cummins executives lay the groundwork for a lively and informative discussion at this year's Commercial Vehicle Engineering Congress & Exhibition.

Simulating cab noise and vibration Researchers at kubota and Doshisha University have established a prediction method for the engine-idling state using statistical energy analysis. Manufacturing cost estimating Caterpillar's ACT Group uses Micro Estimating Systems' computer-aided estimating program to increase efficiency and decrease operating costs in powder-metal part manufacturing. In search of greener pastures Agricultural OEMs are looking at the total life cycle to develop more environmentally conscious products and processes. Emissions and lubrication More stringent diesel emissions legislation is placing an increased burden on engine lubricant in the form of soot loading.
