Abstract

Изобретение относитс к транспортным средствам, в частности к размещению агрегатов и систем двигател в пространстве моторного отсека. Цель изобретени - повышение эффективности шумоглушени и обеспечение компактности. Система содержит моторный отсек 1, в котором установлен ДВС 2 с воздухоочистителем 3, к которому подключена система воздухоподвод щих патрубков, включающа подвод щие 4 и 5 и заборный 6 патрубки и кольцевой трубопровод 7. Длины патрубков 4 и 5, их конкретное размещение в системе, а также площади поперечных сечений патрубков 4 - 6 и трубопровода 7 оптимизированы. 2 з.п. ф-лы, 6 ил.The invention relates to vehicles, in particular to the placement of aggregates and engine systems in the space of the engine compartment. The purpose of the invention is to increase the efficiency of sound attenuation and ensure compactness. The system includes a engine compartment 1 in which an internal combustion engine 2 is installed with an air cleaner 3 to which an air inlet system is connected, including supply 4 and 5 and intake 6 pipes and an annular pipe 7. The lengths of pipes 4 and 5, their specific placement in the system, as well as the cross-sectional area of the pipes 4 - 6 and pipeline 7 are optimized. 2 hp f-ly, 6 ill.

Claims

Claim

1. An air supply system to an internal combustion engine of a vehicle, comprising a motor compartment in which an internal combustion engine with an air cleaner is installed, to which at least one air inlet and intake pipe are connected, characterized in that, in order to increase the noise suppression efficiency and ensure its compactness, it is equipped with an annular pipe and a second air supply pipe, which is connected to the ring pipe, while 10 inlet pipes connecting the cavity of an air purifier with an annular pipeline, are made of the same length, and the lengths of sections of the annular pipeline from the points formed by the intersection of the 15 axes of the inlet pipes with the axis of the annular pipe to the point formed by the intersection of the axis of the annular pipe with the axis of the intake pipe are 1/81 and 3/81, where I - full length 20 of the annular pipeline.

2. The system of pop. 1, with the fact that the cross-sectional areas of the nozzles and the pipeline are in the following

25 addictions:

Fi + F ₂ = 1/2 F ₃ ; Fn> F ₃ , where Fi and F ₂ are the cross-sectional areas of the inlet pipes, m ² ;

30 F3 - cross-sectional area of the intake pipe, m ² ;

Fn is the cross-sectional area of the annular pipeline, m ² .

3, The system of claims. 1 and 2, distinguished by the fact that the annular pipeline, at least part of its length, is formed by the walls of the engine compartment.
