DEVICE FOR EVALUATION OF SOLIDS QUANTITY ACCUMULATED IN SOLIDS DIESEL FILTER Russian patent published in 2011 - IPC F01N3/21 F01N9/00 

FIELD: power industry.

SUBSTANCE: device for evaluation of solids (S) accumulation quantity in solids diesel filter (SDF) is designed for evaluation of S quantity accumulated in SDF provided for S elimination from exhaust gases and it includes the model of S emission quantity evaluation, where S emission quantity is set on the basis of engine operating condition, the model of S regeneration quantity, where S regeneration quantity is set on the basis of temperature difference between output temperature and input temperature of SDF, and the model of SDF differential pressure, where S accumulation quantity is set on the basis of differential pressure between exhaust gases flow speed and SDF. Note that the evaluated quantity of S accumulated in SDF is calculated by summing the corrected quantity of S accumulation received by use of K coefficient that is defined on the basis of engine rotation velocity and number of fuel injections, also the difference between S emission quantity and S regeneration quantity.

EFFECT: provision of improved evaluation accuracy.
