Exhaust gas measuring system

Modern exhaust gas measurement technology is an essential prerequisite for the cooperation of the chair with the automotive industry. Strict legal requirements regarding pollutant emissions force every engine manufacturer today to measure all legally relevant pollutants in the exhaust gas already in the pre-development of an engine in order to adapt the combustion process to the legal requirements. For this purpose, successful pollutant conversion with catalytic converters requires the analysis of the composition of certain exhaust components such as nitrogen oxides, particles and in certain cases hydrocarbon emissions.In gasoline engines fired by natural gas, methane is an important component of hydrocarbon emissions. Methane differs from other hydrocarbons. It is much more difficult to convert methane with conventional 3-way catalytic and oxidation catalytic converters. So it is more difficult to comply with the emission limits for natural gas engines. For this reason, it is necessary to record and measure the proportion of methane emissions separately as early as the concept phase of a natural gas engine. This is possible with the exhaust gas measuring system applied for here, among other things.With the new device, we could measure simultaneously before and after the catalytic converter. This is now state of the art. For this purpose, we would operate the device simultaneously with an existing device from 2009. This is the only way to calculate the conversion rate of the catalytic converter. This is the most important variable for assessing the functionality of a catalyst. It should also be noted that the device developed in 2009 is well utilized. Thus, the new exhaust gas measuring device would help to maintain research operations at a high level.With the help of the new large-scale device, we would also be able for the first time to measure non-limited exhaust gas components with the FTIR spectrometer (Fourier Transform Infrared Spectrometer) to investigate their effects on humans. The spectrometer analyzes or measures components such as ammonia, methane, sulfur dioxide and formaldehyde.For these reasons, which also result from current and future research projects, it is clear that an optical measuring system with spectral analysis is necessary to determine limited and unlimited exhaust gas components.
