Abstract

A vehicle comprises an internal combustion engine having an air supply system comprising a conduit leading from an engine air filter to a remainder of the engine, the engine air filter being located to draw air from an intake inlet, within the enclosed compartment, the enclosed compartment having an openable door, at least one opening, preferably in the door, through which air can pass into the enclosed compartment, and a second filter covering the or each opening. In this way, the second filter can provide a preliminary screen for particulates before the air reaches the engine air filter. This will protect the engine air filter and prolong its life, and reduce the prospects for contamination of the fuel system. Meanwhile, the second filter will be more accessible for cleaning or replacement, either via opening the door to gain access or by locating the second filter on the exterior of the vehicle.

Description

Technical field

Present invention relates to vehicle.

Background technique

Modern internal combustion engines is the fine instrument needing to run in cleaning ambient in essence.Fuel and air with accurate ratio by together with measure, and to burn in clean chamber.Valve and piston operate with tighter tolerances, and fuel is carried via the nozzle of precision.If fuel or air are by Particulate Pollution, especially abrasive particles thing, such as sand or grit, so engine components can become wearing and tearing, and fuel and air system can become blocking.Therefore, motor needs the clean air after supplying filtration wherein, to burn by closing and the fuel of clean system conveying.Consider the significance avoiding causing the impaired pollutant of motor to enter, therefore usually can give engine assembly air and fuel filter, by air and fuel quilt (respectively) suction of this filter motor.These two filter objects are the material IT particulate matters more than certain size at filter; Air filter normally fabric, open room foam or paper, and fuel filter typically comprises the filter paper be encapsulated in suitable box.In addition, fuel tank is usually via the filling of fuel adding neck, and this filling neck comprises the constraint matched with desired fuel nozzle size, and therefore allow fuel tank to be annotated via the system closed, the system closed reduces the risk that pollutant enters.But the action of opening fuel adder is that pollutant creates chance, and its order of severity depends on discussed environment.

From the air of vehicle periphery, suction or the particulate pollutant be allowed to enter in fuel tank are captured and are retained in corresponding filter.Through after a period of time, described filter becomes blocking the most at last, cause the restriction of air to inflow engine or fuel, and result is the degradation of engine performance.Therefore filter must cleaned or usually be changed.This is done usually used as the part in the general maintenance list of vehicle.But the time that in harsh environment, filter blocks required for (especially air filter) may be very short, this means that it is infrequent for changing in this way.This will cause needing to shut down termly, and enter engine compartment, and clear up described filter, this is very inconvenient.In harsh and unforgiving environments, suppose that needs are removed filter by this, also there is obvious motor pollution risk so in this process.

In addition, may need to trek by water as cross-country vehicle, and water never allows to enter described air or fuel inlet, otherwise can occur the immediately of motor and catastrophic damage.So in order to solve this two problems, the vehicle being intended for cross-country purposes can often be equipped with " breathing pipe ", namely leads to the extension tube of the raised position vehicle from air intlet/filter housings.Object is that this raised position will higher than water surface elevation when paddling, and higher than being passed through the height of confused dust (s) by vehicle.But when this is required for maintenance etc., this makes the character close to air filter complicated.

WO2010/049357 and WO2010/049358 shows the design of such tractor cab.Motor is positioned at the below of cockpit area, and is supplied to from location higher than the air that the import of cockpit is introduced.Sealing air tank be arranged near motor, its via from import and the pipeline comprising filter be supplied to.In order to allow close to described filter, need to provide door in air tank.

Summary of the invention

Therefore present invention provides a kind of vehicle, it comprises the explosive motor with air supply system, this air supply system comprises the pipeline of the remaining part leading to motor from air filter for engine, air filter for engine is oriented to from enclosed compartment withdrawing air, this enclosed compartment has openable door, by entering at least one opening of enclosed compartment, and can cover the second filter that is described or each opening by its air, wherein, described door is adjacent with personnel's door.Then, this compartment is also arranged in the fueling system of motor supply fuel.Like this, the second filter can provide tentatively screening out particulate matter before air and fuel arrive motor.This will protect engine air and fuel filter and extend its life-span; and for part or all and (selectively) fuel adder of motor provides cleaner compartment, enter in fuel system, air intlet and like to stop dirt, dust etc.Meanwhile, the second filter will more accessiblely enter via opening door to obtain with clean or replacement, or by the second filter is positioned on the outside of vehicle.

Air filter for engine can be positioned at enclosed compartment, means when needing repairing or change, and can directly enter, but air filter for engine is still protected during use.

Preferably, door is hinged along vertical edge ideally.It can be formed as a part for the outside of vehicle, contiguous personnel's door.This contiguous personnel's door is good, and described or each opening is clean and not by blockings such as dust to be it personnel can be allowed easily to check, and door is fixed rightly when being entered or left vehicle by personnel's door.In this case, be easily, if personnel's door is overlapping with described door at least in part, ideally along the edge of opening of two doors---namely, the overlapping edge of personnel's door at least in part with the superimposed imbricate of described door, and described door is hinged along the edge not being this superimposed edge and personnel's door is hinged along the edge not being this overlapping edge, hinge is all arranged in ideally and is substantially vertically oriented.This means that described door will be fixed on closed position by the action of closedown personnel door.Usually will arrange the lock of certain type for personnel's door, the operator of vehicle is by this lock of custom locking.Therefore, described door easily can be fixed and not need the locking member that adds.

Described door preferably has water-stop with the remaining part of described enclosed compartment.This will greatly stop water enter this compartment and arrive air filter for engine or fueling system, thus allows vehicle by darker fording depth.If except this openable door place, described enclosed compartment is sealed to prevent air from entering substantially, then when closing this to prevent air from entering described enclosed compartment with the dust carried secretly instead of being entered by opening and the second filter, the described water-stop in this also can play a role.At least one opening described is preferably located in the top half portion of described enclosed compartment, thus is further assisted in this respect.

At least one opening described can be arranged in described door self, makes the second filter be easier to close for the operator of vehicle thus, swallow and the state making it current is more obvious.When described door is formed as a part for the outside of the vehicle of contiguous personnel's door, when operator enters vehicle, described second filter operator within sweep of the eye, and will can get at the scope of clapping dust soil or similar operations usually.

Ideally, described second filter is more coarse than described air filter for engine, speed when blocking occurs and maximizes the combined lifetime of two filters, and guide enough air to flow in described enclosed compartment for balancing two filters.Meticulous net grid or coarse open celled foam are desirable concerning the second filter.

Especially the layout being applicable to vehicle is at least part of top described enclosed compartment being positioned at motor instead of air supply system.In addition, personnel compartment can be positioned at least part of top of motor, and enclosed compartment is positioned at after personnel compartment.Described air filter for engine and fueling system are preferably located in (or at least opening with the bottom interval of described compartment) in the upper part of described enclosed compartment, thus make to enter any dust of compartment via described second filter or other particulate matters are deposited in trending towards on the bottom of described compartment, and can not be inhaled in air filter for engine or fuel adder.

Therefore, present invention ensure that the reduction of dust and particulate level in described enclosed compartment, and therefore creates the region that sensing unit can be positioned at wherein.Dust and analog are the primary pollution source of fuel system, and are reduced the expection correspondingly reducing fuel system and pollute by present invention.Have more easily keeping in repair of longer life-span and described second filter together with air filter for engine, therefore this improve the reliability of vehicle.In the presence of a harsh environment, such as, in remote districts and/or away from the road of asphalt road, particularly such.
