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.

Embodiment Construction

[0024] Such as Figure 1~4 As shown, a high-precision detector for diesel engine exhaust smoke includes a detector body that is in a nearly hemispherical structure; the detector body includes an outer cover hemisphere 1 and an inner cover hemisphere 2, and the inner cover hemisphere 2 The cover hemisphere 2 is distributed inside the outer cover hemisphere 1, and there is a gap between the outer cover hemisphere and the inner cover hemisphere to form a hemispherical exhaust cavity 4; the top of the outer cover hemisphere is provided with a smoke exhaust pipe 5. There is an exhaust fan 6 in the flue gas exhaust pipe; the exhaust fan uses a servo motor to drive the fan blades, mainly for the controllable adjustment of different smoke concentrations required by different models, and once a certain model is tested and obtained After the optimal detection concentration (need to comprehensively consider parameters such as air flow stability and smoke concentration settling property),...

Abstract

The invention discloses a high-precision detector for the diesel engine emission smoke intensity. The detector comprises a detector body which is of a near-hemispheroid structure. The detector body comprises an outer cover hemispheroid and an inner cover hemispheroid, the inner cover hemispheroid is distributed in the outer cover hemispheroid, and a gap is reserved between the outer cover hemispheroid and the inner cover hemispheroid to form a hemispheric exhaust empty groove. A smoke exhaust pipe is arranged at the top of the outer cover hemispheroid, and an exhaust fan is arranged in the smoke exhaust pipe. According to the invention, high-precision and stable detection can be realized.

Description

technical field [0001] The invention relates to the technical field of high-precision detection of diesel engine exhaust smoke, in particular to a high-precision detector for diesel engine exhaust smoke. 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 of this patent application ...
