For exhaust gas measurement our high altitude chamber is equipped with a roller test bench and an air fan. It supports both industry-standard and customer-specific test cycles (e.g. the New European Driving Cycle (NEDC) or the US Federal Test Procedure (FTP75).
During a driving cycle, two sampling lines are used to continuously measure the CO, CO2, NOx, THC and CH4 emission values. Using this method, the integral concentrations of emissions can be determined for up to four phases during the driving cycle. The system also supports gravimetric particle measurements.
The high altitude chamber can also be used for analysing engine components and for adjusting the respective control units based on defined deployment and load conditions in order to analyse and optimise powertrain characteristics. By controlling and monitoring environmental conditions measurement results can be reproduced and compared over various periods of time.
