Introduction

This outline is applied to filter type of pattern evaluation, the evaluation given filter type meets the performance standard Basic test conditions and test methods required for registration. This outline is based on JJF 1015-2014 "measuring equipment type and universal norms" and JJF 1016-2014 "count Evaluation of the amount of equipment type outline guidelines for the preparation "Writing; the technical content of this outline the main reference JJG847-2011 "Filter type" and HJ553-2009 "smoke card." The outline for the first time to develop. Filter type pattern evaluation outline

3 Terms

3.1 smoke smoke Black level filter paper. NOTE. smoke smoke, also known as filter paper with 0-10 Bosch smoke Unit (BSU), ie clean filter paper as 0BSU, black filter Paper as 10BSU, from 0 to 10 degrees evenly by the formula (1). Rb = (1-ρP/ρ0) × 10 (1) Where. Rb --- smoke, unit. Bosch smoke Unit (BSU); ρP --- is the reflection factor after Black filter paper; ρ0 --- Clean the filter of the reflection factor. 3.2 exhaust volume sweptvolume Smokemeter pump pumping a pumped volume of gas in milliliters (mL). 3.3 extraction time pump-downtime The pump piston time required to complete the entire trip in seconds (s). 3.4 Leakage leakagevolume Exhaust pump system, the piston and the edge of the filter paper is clamped leaking gas volume in milliliters (mL).

4 Overview

Exhaust smoke meter used to measure the compression ignition engine (also known as a diesel engine) or with compression-ignition engines of motor vehicles Gas smoke. Smokemeter sampling system consists of two parts and measuring system. Sampling system includes a sampling probe and sampling connection Tube, suction device; measuring system includes a measuring probe, filter insertion device and display instruments. ......
