The chassis dynamometer device is a device that can be used to adjust the car engine dynamically. The main task of a dynamometer device is to simulate the road conditions for the car, and by using it, it is possible to perform various tests on the car without the need to perform a road test. Usually, when the car is placed on the dynamometer, its important parameters such as revolutions and torque of the main wheel are measured and displayed. These parameters are very important and vital for adjusting the car engine. This device is used for ECU calibration and tuning of injection cars and checking the effect of changing engine system components on the car.

Ever since the problem of pollution of big cities and greenhouse gases became a global crisis, governments thought to control this crisis by reducing polluting gases produced by cars, which have a greater share in the production of pollution in cities. In this way, various car emission standards such as Japanese, American and European standards were compiled. Our country complies with European emission standards. In each emission standard, there is a certain driving cycle, which is called Driving Cycle. The car is placed on the chassis dynamometer under certain conditions and the tester runs the desired driving cycle on the dynamometer. During the driving cycle, exhaust gases are collected and at the end of the cycle, their amount is measured and calculated. If the amount of polluting gases during the cycle is less than the range specified by the standard, the car is said to have passed the emission standard.
The pollutant gas measurement equipment is completely independent from the dynamometer device and is not considered a part of the chassis dynamometer. In other words, only to carry out pollution tests (for surveying the driving cycle), pollutant gas measurement equipment with a dynamometer should be purchased. It is also important to note that the dynamometers used for emission tests are inertial or asynchronous, which are much more expensive than breaking dynamometers.
