The HORIBA MEXA-2100SPCS system determines the number of solid particles in the raw exhaust gas of combustion engines in real time. Particles as small as 10 nm can be detected.

The AVL Micro Soot Sensor with exhaust gas conditioning unit is used for time-resolved measurement of the soot concentration in combustion engines both before and after the particulate filter. The photoacoustic measuring principle enables precise results even for low soot values. The AVL Micro Soot Sensor is additionally equipped with a dilution and a pressure reduction unit.

The AVL Smoke Meter is used for stationary measurement of the soot concentration in the exhaust gas of combustion engines. It works according to the filter paper method and determines the Filter Smoke Number (FSN). The measuring device offers the possibility of using two sampling lines and thus switching between different sampling points.

The AVL Particle Counter Advanced is used for particle number measurement. Sampling is possible both from a CVS tunnel and directly on the raw exhaust gas. The adjustment of the CPC enables a Euro 7-compliant counting efficiency of 65 % (+/-15 %) at 10 nm and >90 % from 15 nm. The counter also has a catalytic stripper.

The Dekati® eDiluter™ Pro is a portable dilution system for particle measurements with an adjustable dilution factor from 1:25 to 1:900. It dilutes samples in two stages, with the first stage being heated. An integrated catalytic stripper removes volatile particles and the overall system has low particle losses. It fulfills EURO6+ requirements and allows measurements up to 1200 °C.

The Palas® VKL 10E dilution system made of stainless steel is suitable for chemically aggressive aerosols and has a fixed dilution factor of 1:10. It requires little compressed air, operates isobarically up to 10 bar back pressure and isothermally up to 120 °C. Compatible with all common particle counters, including simple on-site functional testing.

The Catalytic Stripper (CS) from Catalytic Instruments GmbH & Co. KG is a heated element for removing solid and gaseous semi-volatile components from exhaust gas aerosols from combustion engines. It enables precise measurements of solid particles in accordance with legal requirements and the analysis of the effects of new fuel and lubricant formulations on combustion. The inlet flow is 10 l/min.

Injection analyzer

The IAV Cross injection analyzer records the injection behaviour of injectors, including the injected mass and the high-resolution time curve. The measuring principle enables the precise analysis of conventional and alternative fuels and their effects on the injection process. In addition to liquid fuels, the injection of gaseous fuels such as hydrogen and methane can also be investigated in the IAV-Cross.
