Device of testing particles in tail gas exhausted from automobile

摘要

A device of testing particles in a tail gas exhausted from an automobile contains: an intake unit, a smoke detection unit, a processing unit, and a filtering unit. The filtering unit includes a filtration chamber, a filter paper, and two weighing elements. The filtration chamber has a locking portion and an opening. A transmission belt is mounted beside two sides of the filtering unit and has an upstream segment and a downstream segment, and between the upstream segment of the transmission belt and the locking portion is defined a first weighing element, between the locking element and the downstream segment of the transmission belt is defined a second weighing element. A first delivery sucker, a second delivery sucker, and a third delivery sucker are all mounted in a filtration chamber. Thereby, a total weight of particles in a tail gas is measured within a unit time.
