[0021] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and not to limit the present invention.
[0022] The method for estimating the carbon loading of a diesel engine exhaust particle trap of the present invention includes the following steps:
[0023] 1) Select the steady-state working condition of the diesel engine and determine the exhaust gas flow rate through the diesel engine exhaust particle trap under this working condition;
[0024] 2) Determine the corresponding front and rear pressure drops of the diesel engine exhaust particulate trap under the exhaust flow under no-load and limited load conditions;
[0025] 3) Build a mathematical model for calculating the carbon load of the diesel engine exhaust particulate trap according to the corresponding pressure drop value of th
