Apparatus Setup:
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. The exhaust gas analyzer checks the target gases which are NO, HC, CO when black smoke and PM are separated from the exhaust gas. The data processor evaluates the outcomes of the experiment and instructs the analytical and measuring apparatus (Exhaust Gas Measurement for Motor Vehicles).
Experiment Methodology/ Procedure
The first procedure is to organize the exhaust gas evaluation which is done by: choosing a car, sampling on-road running resistance figures, setting up the test car, and modifying the gauging apparatus. The start conditions are then determined because characteristics of the exhaust gas of automobiles differ at the start of driving as compared to driving afterwards. The evaluation of the car’s operation is carried out followed by Exhausts gas estimates. The exhaust gas estimates are either from dilute gas or direct gas. In unsteady driving, the diluted gas method is usually used. If under steady driving the direct gas procedure is used, fuel intake and air consumption must be determined concurrently. Finally the black smoke is analyzed and determined. During evaluations, either a chassis dynamometer or an engine dynamometer is used. The black smoke information helps in the load-less fast accelerating form (Four and ...
