Problems solved by technology
[0002] When the engine leaves the factory, it is necessary to test the engine exhaust smoke level. The current engine exhaust smoke level test is highly disturbed and has low accuracy.
Especially for diesel engines, the cylinder stroke reciprocates and the smoke exhaust is also unstable. Therefore, the detection of existing devices fluctuates greatly and cannot be accurately detected.

The invention discloses an air pressure precise control centrifugal turntable type diesel engine emission smoke intensity detection device which comprises an outer shell. A detection turntable is distributed in the outer shell, the detection turntable is driven by a servo motor, and the servo motor is combined on the outer shell. Transparent rings are correspondingly arranged on the upper surfaceand the lower surface of the detection turntable respectively; a detection chamber and a light source head chamber are respectively and correspondingly distributed outside each transparent ring; the detection chamber and the light source chamber are combined on the outer shell; a flue gas inlet pipe is combined with the middle part of the lower disc of the detection turntable and is connected through a rotating shaft; fan blades are distributed at a circle of air outlets in the outer edge of the detection turntable. According to the invention, rotary and controllable smoke intensity accurate detection can be realized.
Description
technical field [0001] The invention relates to the technical field of accurate detection of diesel engine smoke, in particular to a gas pressure precise control centrifugal rotary disc diesel engine exhaust smoke detection device. Background technique [0002] When the engine leaves the factory, it is necessary to test the engine exhaust smoke level. The current engine exhaust smoke level test is highly disturbed and has low accuracy. Especially for diesel engines, the smoke exhaust caused by the reciprocating stroke of the cylinder is also unstable, so the detection of the existing device fluctuates greatly and cannot be accurately detected. [0003] The disclosure of the above background technical content is only used to assist in understanding the concept and technical solution of the present invention, and it does not necessarily belong to the prior art of this patent application. If there is no clear evidence that the above content has been disclosed on the filing date...
