Abstract

The invention discloses evaporative emission testing equipment for parts of an automobile fuel system. The equipment comprises a first closed chamber and a second closed chamber, the first closed chamber is communicated with the second closed chamber through a plurality of communicating pipes, and the first closed chamber and the second closed chamber are connected with a same flame ion hydrocarbon analyzer through sampling pipes provided with valves respectively. The equipment has the beneficial effects that the evaporative emission values of a fuel tank and a carbon tank can be tested and obtained at the same time, a large amount of time is saved for a user, and due to the fact that a fuel system is tested in a regional mode, the equipment has very remarkable advantages in terms of search of standard-exceeding components in the development stage; and a user can simultaneously or respectively carry out two different tests on the basis of only inputting one flame ion hydrocarbon analyzer, so that the test capability is doubled, and the test cost is effectively saved.

Description

technical field [0001] The invention relates to the technical field of evaporative emission testing equipment, in particular to an evaporative emission testing equipment for automotive fuel system components. Background technique [0002] The evaporative emission test or the evaporative pollutant test is a type IV and VII type test for light-duty vehicle pollutant emission limits and test methods (China's sixth stage), which detects other hydrocarbons except the exhaust pipe of the vehicle. The sum of compound emissions. The evaporative emission test process of the whole vehicle needs to carry out a series of preparations such as filling and discharging oil, pretreatment cycle, butane pretreatment carbon canister, etc., and then push the experimental vehicle into the airtight room and conduct heat treatment according to the regulations. In the immersion test and day and night ventilation emission test, the carbon ion concentration inside the airtight chamber is detected by ...
