Embodiment 1

[0062] The present embodiment provides a system and method for detecting the sulfur content of diesel fuel for vehicles, the system is the same as the system described in the specific embodiment, and the method is the same as the method in the specific embodiment section.

Embodiment 2

[0064] The present embodiment provides a system and method for detecting the sulfur content of diesel fuel for vehicles. The system is the same as the system described in the specific embodiment, and the method is based on the method in the specific embodiment, and the difference only lies in: step (2) , the sulfate quality also needs to be divided by SO 2 conversion rate, and then calculate the S mass according to the law of conservation of mass.

Abstract

The invention provides a system and a method for detecting the sulfur content of automotive diesel oil. The system comprises an oxidation catalysis system and a PM sensor, the PM sensors are independently arranged on the upstream and downstream of the oxidation catalysis system respectively; the system is different from a traditional post-treatment system, PM sensors are arranged on the upstream and downstream of the oxidation catalysis system, the sulfur content in diesel oil can be obtained by measuring the PM mass difference before and after the oxidation catalysis system and assisting with simple and convenient calculation, and the purpose of online rapid detection is achieved.

Description

technical field [0001] The invention belongs to the technical field of sulfur content detection, relates to a system and a method for detecting the sulfur content of diesel fuel for vehicles, and in particular relates to a system and method for detecting the sulfur content of diesel fuel for vehicles by using a PM sensor. Background technique [0002] Diesel has a high sulfur content, and the sulfur compounds in the exhaust gas produced by combustion will poison the aftertreatment catalyst, resulting in excessive emissions. Active sulfur can directly corrode metals, and no matter active sulfide or inactive sulfide, sulfur dioxide and sulfur trioxide generated after combustion encounter water and water vapor generated by combustion, and will form sulfurous acid and sulfuric acid at high temperature, which will seriously corrode the engine. parts. In addition, acidic substances will cause the total base value of the oil to drop rapidly, and the oil change cycle will be greatl...
