HORIBA is cooperating with the Universitat Politècnica de València (UPV) on the joint development of a mobile altitude simulation system. The new joint solution will be available in September 2015.

Requirements of the market

Due to the requirements of global production for global markets, OEMs require a high transparency and comparability of the development process and a high correlation of measurement results at different Research & Development locations. As a result of the significant influence of the altitude on combustion-related emissions and engine performance, the altitude and the corresponding air pressure, temperature and humidity are significant parameters with regard to correlation and round robin tests.

With new legislation to come, the topic of real driving emissions is becoming more and more important. To ensure that a combustion engine meets the specified requirements with regard to performance and global emission standards, altitude has to be simulated under overpressure and underpressure conditions. Because of the increasing demands of the markets, those tests are not only limited to vehicle tests but are required for engine testing as well.

The new solution

On the basis of these market demands, HORIBA decided to cooperate with UPV to launch a very reasonably sized mobile altitude solution to be used for intake air pressure and exhaust pressure conditioning in engine dynamometer, driveline and chassis dynamometer applications. Its excellent performance allows altitude simulation up to about 6000 m with an accuracy of more than 5 m of altitude and allows the temperature to be controlled very accurately too. A humidity control is extremely easy to expand. In addition, the patented physical principle ensures highest dynamic response and efficient energy consumption.

Background: Current solutions

Altitude test chambers: These are expensive and inflexible in the case of high testing capacities.
Tests in real-altitude ambient conditions: Considerable effort is required to ship the test equipment around the world.
Altitude simulation tools: Current solutions are neither flexible nor accurate or dynamic enough and have a high energy consumption.
