resulting error

Purpose. Increase of ecological safety of thermal engines by improving the standardized method for measuring exhaust emissions of the main component - weighted (particulate) matter. Methods. Analysis and synthesis of information, mathematical modeling, experimental studies, computational experiment. Results. Analyzed the environmental standard procedure of diagnosing automotive diesels. Studied the resulting measurement error average in-use release of particulate matter from the exhaust gases. Proposed measures for its reduction. Conclusions. The accuracy of the gravimetric method of measurement of particulate matter emissions. It confirmed the effectiveness of measures for the improvement of this method, which allows 4.6 times increase its accuracy.
