Short Preview Below

“Spotlight on Design” features video interviews and case study segments, focusing on the latest technology breakthroughs. Viewers are virtually taken to labs and research centers to learn how design engineers are enhancing product performance/reliability, reducing cost, improving quality, safety or environmental impact, and achieving regulatory compliance.

Accurate data is critical for the testing and development of parts and systems for cars, trucks, and airplanes. To obtain this data, engineers rely on high-end specialty sensors that can fit into cramped spaces and operate reliably under extreme heat and pressure.

In the episode “Sensors: Miniaturization and Testing” (21:02), AVL engineers explain how a new crystalline material was developed to accurately measure the high pressures in the combustion chamber of turbocharged engines, and Meggitt Sensing Systems profiles the world’s smallest triaxial IEPE accelerometer.

This episode highlights multiple areas of interest, including:

- Background and definitions of the miniaturization of sensors

- Profile of the world’s smallest triaxial IEPE accelerometer

- A look at engine pressure sensors based on gallium orthophosphate

- A look at a single cylinder research engine used to evaluate sonar pressure transducers

- Future trends

    Sensing exhaust gas temperature is a key component in diesel after treatment systems for both control and diagnostics. Accuracy varies significantly depending upon the sensing technology and implementation in the system. Prior published work has demonstrated that resistance based temperature sensors are not able to achieve the system accuracy required for advanced diagnostics over the life of the emission system. This presentation will show that it is feasible to achieve better than �10�C end of life system accuracy by means of active thermocouple technology. Results from tests at Michigan Technological University will be used to illustrate diagnostic uncertainty related to the application of temperature sensors and a specific DOC/DPF example will be used to show the benefits of accurate temperature based diagnostics.

    The presentation describes technology developments and the integration of these technologies into new emission control systems. As in other years, the reader will find a wide range of topics from various parts of the world. This is reflective of the worldwide scope and effort to reduce diesel exhaust emissions. Topics include the integration of various diesel particulate matter (PM) and Nitrogen Oxide (NOx) technologies as well as sensors and other emissions related developments. Presenter Atsuo Kondo, NGK Insulators, Ltd.

    “Spotlight on Design: Insight” features an in-depth look at the latest technology breakthroughs impacting mobility. Viewers are virtually taken to labs and research centers to learn how design engineers are enhancing product performance/reliability, reducing cost, improving quality, safety or environmental impact, and achieving regulatory compliance. Automated driving is made possible through the data acquisition and processing of many different kinds of sensors working in unison. Sensors, cameras, radar, and lidar must work cohesively together to safely provide automated features. In the episode “Automated Vehicles: Converging Sensor Data” (8:01), engineers from IAV Automotive Engineering discuss the challenges associated with the sensor data fusion, and one of Continental North America’s technical teams demonstrate how sensors, radars, and safety systems converge to enable higher levels of automated driving.

    "Spotlight on Design" features video interviews and case study segments, focusing on the latest technology breakthroughs. Viewers are virtually taken to labs and research centers to learn how design engineers are enhancing product performance/reliability, reducing costs, improving quality, safety or environmental impact, and achieving regulatory compliance. Sensors are essential to the safety, efficiency, and dependability of modern vehicles. Crash sensors can anticipate a collision faster than humans would, and tire pressure sensors can alert the driver or pilot in case action is needed. In the episode “Sensors: Advanced Safety” (20:36) Continental engineers look at the evolution of passive safety systems, discuss the changes in sensors over the last ten years and what is coming next. Engineers at Meggitt demonstrate how tire pressure monitoring system sensors for aerospace are built and tested.
