This equipment is used to determine the resistance of vehicles against skidding on the roads.

• MEXA-6000FT-E series measures concentrations of multiple gaseous species in the engine exhaust using the Fourier Transform infrared (FTIR) method in combination with a multivariate analysis algorithm.

• It applies to various applications, such as evaluation of nitrogen components in catalyst development. The new MEXA-6000FT-E meets the NH3 testing requirements for the next EU regulation for heavy duty emission, Euro (draft), and measures NH3 and 30 other non-regulated emission species, simultaneously.

• Fourier transform infrared spectrometry (FTIR) is a method for obtaining infrared absorption spectrum of high resolution by a combination of an interferometer and high speed Fourier transformation. Since lots of components have their unique spectrum in the infrared region, this method is used for quantitative and qualitative determination in various fields.

• Infrared light radiated from a light source becomes an interference light, passes through the cell in which sample gas is flowing, and then enters the detector. The spectrum of the infrared light that pass the cell can be obtained by converting the signal obtained here by means of fast Fourier transformation.

• For qualitative and quantitative analysis, the power spectrum in a case where a zero gas is flowing in the cell is separately measure, and the infrared absorption spectrum for the sample gas is calculated from the proportion of the both spectra.

• The spectrum obtained is the superposition of spectra of multiple components that show absorbance in the mid infrared region.

• High speed combustion data acquisition system for recording pressure-crank angle signals from the engine combustion chamber.

• HCCI is an hybrid engine technology, which combines the advantages of Spark Ignition (SI) Engines and Compression Ignition (CI) Engines.

• It provides efficiency as high as CI Engines and Ultra-low NOx and PM emissions.

• The charge inducted in the cylinder is homogenous which burns volumetrically throughout the combustion chamber simultaneously, thus reducing PM emissions however the combustion temperature is also comparatively lower, therefore NOx formation is also highly reduced.

• This is a two cylinder, constant speed, 4 stroke, air cooled, direct injection diesel engine. One out of the two cylinders is modified to run on HCCI mode, while the other cylinder runs on conventional diesel combustion mode.

• A dedicated device is used as diesel vaporizer for vaporization of diesel, which helps in homogenous mixture formation. The fuel is injected in the cylinder using port fuel injection.

• Start of combustion is being controlled by Exhaust Gas Recirculation (EGR). EGR dilutes the mixture in the cylinder and reduces the oxygen content and in turn controls the start of combustion inside the combustion chamber.

• High speed data acquisition system is used to acquire data from the engine. It allows simultaneous monitoring, processing and recording of various data sets from the engine.
