ASM 4WD acceleration simulation emissions bench

The ASM emissions test bench for 4WD vehicles can prevent, locate and investigate possible ignition and injection problems, as well as improve fuel consumption and measure vehicle emissions under load.

During emissions testing, power absorption in accordance with the ASM standard is achieved by means of an air-cooled electric brake. It consists of a double steel monocoque frame housing two rollers facing each other per wheel at the front and four rollers per wheel aligned at the rear. The front rollers of the first frame are coated with tungsten carbide to improve vehicle grip and prevent roller wear.

The entire assembly is linked to an energy-absorbing electric brake. In addition, to facilitate access to and exit from the vehicle, it has a pneumatically operated locking lifting mechanism. Equipped with a clutch that allows the front and rear parts to be engaged or disengaged.

Compatible with our gas analysers EIS-5000, RY-500AG RY-4000AG (Click on the names to learn more about each analyser)
