Abstract

The invention provides a heavy-duty truck air inlet passage assembly which comprises a straight-through type spiral pipe, an upper air inlet passage, a transverse air inlet passage and an air filter,wherein the upper air inlet passage comprises an upper air inlet passage body; at least two groups of air inlet partitions are arranged in the upper air inlet passage body to divide the upper air inlet passage body into at least three air inlet areas; a corrugated pipe is arranged at the air outlet end of the upper air inlet passage body; the transverse air inlet passage comprises a transverse airinlet passage body as well as a guiding structure and a water drain valve arranged on the transverse air inlet passage body; the guiding structure is arranged at the connecting part of the transverseair inlet passage body and the corrugated pipe; the water drain valve is arranged at the maximum cross section position of the transverse air inlet passage body; and the air outlet end of the transverse air inlet passage body communicates with the air filter. The heavy-duty truck air inlet passage assembly is simple in structure, compact in design and convenient to mount and dismantle, can save the mounting space, also can improve the water removal efficiency and the dedusting effect of the air inlet passage and deserves popularization.

Description

technical field [0001] The invention relates to the technical field of air intake systems, in particular to an air intake duct assembly of a heavy-duty truck. Background technique [0002] As an important part of the air intake system, the intake duct mainly plays the role of water and ash removal to ensure the dryness of the air filter element and high ash removal and pre-filtration efficiency. Its structure directly affects the quality and cleanliness of the air entering the engine. These factors directly affect the power, economy and service life of the engine. [0003] In the prior art, the air intake pipes of the air intake system are of various forms, good and bad. Affected by the negative pressure of the engine, the air intake flow and velocity in the air intake are not uniform, which will easily lead to an increase in the intake of dust and water, aggravating the The burden of the air filter causes the failure of the air filter, which in turn causes insufficient pow...
