LYD-3B Diesel vehicle exhanst emission test

LYD-3B Diesel vehicle exhanst emission test

Automotive Inspection LinesMainly used to determine the exhaust smoke of various types of diesel vehicles, but also to do other smoky determination. This instrument belongs to the filter paper smoke meter, its main technical indicators and use methods and SIDPO (Bo Sch) The smoke meter is basically the same. This instrument uses photoelectric detection principle to quantitatively determine carbon smoke sampling,Using high-performance single-chip microcomputer design, the use of red digital tube display measurement data, intuitive interface, clear reading. Its mechanism is simple, flexible operation, easy to use, stable performance, reliable operation, accurate, good repeatability, sampling can be saved, easy to re-school and other characteristics. The exhaust smoke degree of diesel vehicle is an important project in bench test, which is an important index to evaluate the performance of diesel engine, it is a parameter to evaluate the strengthening performance of diesel engine and whether the combustion process is good, so it is of great significance to correctly determine the exhaust smoke degree of diesel vehicle..
