Abstract
The utility model relates to an installation technique of an engine air cleaner of a passenger car, and solves the problems of the prior art, such as too many air inlet elbow pipes, large gas-flow resistance, complicated structure, and poor heat radiation of engine. The utility model provides a city bus with a top-mount air cleaner, wherein the air cleaner is arranged inside an air-conditioning air channel on the top of the city bus, and air inlet pipelines of the air cleaner and an engine booster are arranged inside a space between the air-conditioning air channel and the posterior of an engine chamber. The utility model utilizes the redundant space of the air-conditioning air channel on the top of the city bus to store the air cleaner, so as to omit the fixation supporter and simplify the fixation structure. The air inlet pipeline is directly communicated with the air inlet of the engine booster, so as to reduce the gas-flow resistance and simplify the pipeline structure. An air inlet of the air inlet pipeline is positioned in teh top space with low dust concentration, so as to prolong the service life of the filter core and ensure the reliable operation of the engine.
Description
Technical field
The utility model relates to the field engineering of bus engine airfilter, in particular BRT passenger vehicle airfilter field engineering.
Background technology
Airfilter is as assembly parts of bus engine air system, and its installation is provided with the installation of generally adopting in the engine bin structure is set, shown in the scheme drawing of Fig. 1.The technical problem underlying that this mounting structure exists is: airfilter 1 ' the work in higher engine bin of temperature 6 ' in, cause Engine Inlet Temperature higher equally, totally unfavorable to engine radiating; This installation form must make the air hatch of airfilter approach the high ground of dust turbidity and be provided with, and has strengthened the work load of airfilter, has shortened the service life of air-filter insert, has also influenced the normal of driving engine greatly; By the airfilter admission port to blwr admission port 4 ' between pipeline jointing construction comparatively complicated, and relate to many elbows and connect, these bend pipe structures had both strengthened intake air restriction and air intake roar, be unfavorable for entire car denoise, but also needing sebific duct, the steel pipe of a greater number, the connection and the fixed parts of clip, its air-tightness is difficult to guarantee, and needs bigger bracket institution 8 to fixedly install, strengthen complete vehicle weight, increased manufacturing cost; Its again a key technical problem be: this set-up mode has been occupied between limited engine air, bring very big difficulty on the one hand the maintenance of driving engine, and its body be provided with structure also be easy to this storehouse in other annex in space be provided with mutually and disturb, be unfavorable for the car load setting of each parts.
The utility model content
Goal of the invention of the present utility model be to avoid engine bin the installation setting, a kind of airfilter overhead type city bus is provided.Airfilter overhead type city bus technical scheme of the present utility model, its major technique content is: a kind of airfilter overhead type city bus, its airfilter is installed and is arranged in the air-conditioning duct space at passenger vehicle top, and air-conditioning duct is provided with the admission line of airfilter and engine supercharger to the car body of engine bin in the confining space.
The airfilter overhead type city bus technical scheme that the utility model provides, the clearance spaces that has made full use of the vehicle body upper portion air-conditioning duct in design is provided with airfilter, not only saved original fixing support rack, simplified fixed sturcture, and avoided the space that is provided with of engine bin, therefore be not subjected to that engine operation is hi-heat to be influenced, for driving engine cooling work provides favourable service conditions; Because the admission port of airfilter promotes and places the passenger vehicle head room thereupon, away from the dense space, road surface of dust, the air that enters airfilter more cleans, thereby prolongs the life-span of air-filter insert, has also fully ensured the driving engine normal working performance; The overhead structure of airfilter has also reduced its air hatch to the bend that increases between the device admission port, air-flow resistance is little, air-flow is more smooth and easy, and its pipeline simple structure, provide convenience for setting up intake muffler on the pipeline, can make the engine bin noise reduce the 5-10 decibel.
Description of drawings
Fig. 1 is the mounting structure scheme drawing that airfilter is installed on engine bin in the original coach
Fig. 2 is the local general assembly scheme drawing of airfilter overhead type city bus of the present utility model.
The specific embodiment
The airfilter mounting structure of airfilter overhead type city bus of the present utility model as shown in Figure 2, its airfilter 1 is fixedly mounted in the air-conditioning duct space 5 of top, passenger vehicle rear portion, the air hatch of airfilter 1 is opened on the passenger vehicle side housing, the admission line of airfilter 1, promptly gas inlet rubber tube 2 pass air-conditioning duct to the car body back wall spatial communication of engine bin 6 to engine supercharger admission port 4.Said structure is for setting up silencer, reducing the passenger vehicle noise and created condition, and in this enforcement structure, admission air silencer 3 is arranged on gas inlet rubber tube 2 pipelines.
Claims (2)
