Embodiment Construction

[0039] The specific embodiment of the present invention will be described in further detail by describing the embodiments below with reference to the accompanying drawings, the purpose is to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solutions of the present invention, and contribute to its implementation.

[0040] Such as figure 1 As shown, the present invention provides a kind of ash sample preparation method, comprises the steps:

[0041] S1. Determine the ash content target value of the particle trap;

[0042] S2. Accumulate the ash content through the bench test, and make the ash content sample;

[0043] S3, verifying the ash sample.

[0044] Specifically, in the above step S1, there are two methods for calculating the target ash content of the particle trap. One of the calculation methods is the fuel consumption calculation method of the whole vehicle, and the other calculation method is the...

Abstract

The invention discloses an ash content sample piece manufacturing method. The method comprises the following steps: S1, determining an ash content target value of a particle trap; S2, performing ash accumulation through a bench experiment, and manufacturing an ash sample piece; and S3, verifying the ash content sample piece. According to the ash content sample piece manufacturing method, the influence of actual ash content on the particle trap can be actually reflected, the manufacturing period is short, implementation is easy, and meanwhile the ash content sample piece is good in repeatability.

Description

technical field [0001] The invention belongs to the technical field of automobile exhaust treatment, in particular, the invention relates to a method for making an ash sample. Background technique [0002] "Light Vehicle Pollutant Emission Limits and Strategies (China's Sixth Stage)", that is, the National VI Standard for Light Vehicles, was officially released on December 23, 2016. After the promulgation of the National VI Standard and the National V Standard Regulations, the main changes are as follows: : Changed the type I experimental test cycle, tightened the pollutant emission limits, increased the measurement requirements for the number of particulate matter emitted by gasoline vehicles, and changed the actual driving pollutant emission (RDE) experiment to a type II experiment. In order to meet the changes in this standard , OEMs generally adopt the technical route of particle traps to meet regulatory requirements. But after adding the particle filter, since the engi...
