: The apparatus necessarily for determining motor vehicle exhaust gases are those that reconstruct road running status (power absorption and control), exhaust checking systems, gas analyzers, and data processor. The apparatus that take in motive power produced is known as dynamometer which consists of different control apparatus and other devices attached to it. The dynamometer also enhances road resistance. The engine dynamometer allows a compact system to be implemented, thus producing successful experiments. The exhaust gas sampling apparatus consist of: direct gas sampling, dilute gas sampling, and the dilution tunnel.
