MOT No. 8
This test is carried out in the workshop as part of the annual exhaust emission test. At the same time, the CO content is measured both at the catalyst inlet and at the exhaust pipe. The results of the readings taken are compared with each other. With the help of a special table, the degree of neutralization of CO in the catalyst is determined. If the efficiency of the catalyst is below 50% when neutralizing CO, then the catalyst or lambda probe is damaged.
