Description
Technical field
It relates to a kind of explosive motor.
Background technology
Single cylindrical type engine is known the most in this field.But, single cylindrical type engine is mainly nature
Air-breathing.The electromotor of natural aspiration can be defined as such electromotor, wherein not by outside any
The air that portion's air aerating device (such as supercharger or turbocharger etc.) is introduced into electromotor fills
Gas pressurizes.The electromotor with 3 or more multi cylinder uses turbocharger to realize being directed to these
The purpose of the supercharging air in the cylinder of motivation.But, make in single air-cylinder type or two cylindrical type engine
Identical advantage can not be brought, because in single air-cylinder type or two cylindrical type engine by turbocharger
Exhaust flow rate is relatively small.Further, in single air-cylinder type or two cylindrical type engine, flow velocity can be based on starting
Machine ruuning situation keeps fluctuation or vibration.The row of these vibrations in single air-cylinder type or two cylindrical type engine
Gas velocity can reduce turbocharger efficiency and thus shadow reduce electromotor whole efficiency.From electromotor
The most crucially fume emission from the viewpoint of operation.Especially, single air-cylinder type or two air-cylinder types start
Machine is extremely sensitive to fume emission under the most at full capacity.The power requirements of these put-puts and
Torque characteristic cause the use to these electromotors close at full capacity or place under full capacity.
Additionally, it is necessary to provide one to have cost-efficient mode, wherein can send out for such low capacity
Motivation obtains higher lambda value.In such as India of some emerging nations, for BS3 and BS4 electromotor
Positive validation test (positive certifications test) the highest typically desired lambda value.Cause
This, for such low capacity electromotor (such as single air-cylinder type or two cylindrical type engine), work as electromotor
When being under full load condition, air inflation can available under any engine operating state be very
Important.
The such application for explosive motor is disclosed in patent documentation EP151407.This patent literary composition
Offer the explosive motor disclosing a kind of supercharging.According to the disclosure in document, aerofluxus is for driving supercharger
Rotor.Additionally providing the motor being connected to this rotor, it can be also used for driving this rotor.It is hereby based on sending out
The running status of motivation, described supercharger is driven by aerofluxus or motor.Particularly under big load condition,
Owing to aerofluxus is not enough to drive supercharger to drive the air required for electromotor to inflate, so motor is used to provide
Drive supercharger.
Accompanying drawing explanation
Embodiment of the disclosure and describe combining following accompanying drawing.
Fig. 1 illustrates the miscellaneous part together with the air system of explosive motor of the explosive motor according to the present invention
Schematic diagram.
Detailed description of the invention
Fig. 1 illustrates the miscellaneous part together with the air system of explosive motor of the explosive motor according to the present invention
Schematic diagram.Explosive motor 10 includes: at least one cylinder, and it is applicable to receive from air inflation dress
Put at least air inflation of 12.Explosive motor 10 is characterised by so that explosive motor 10 is applicable to connect
The air from air aerating device 12 of receiving is inflated so that the inflation of this air is in the full range of speeds of electromotor
In 200-800mbar scope.According to the disclosure, in the air system of explosive motor 10 described in use
Air aerating device 12 is mechanical supercharger.
The schematic diagram that figure 1 illustrates can be as described below.Explosive motor 10 is low capacity electromotor.For
The apparent purpose of the disclosure, it is contemplated that be list cylindrical type engine to explosive motor.Internal combustion is sent out
Motivation 10 is provided with air system.Described air system includes two important inlet air flow path, i.e. air inlet paths
Footpath and exhaust pathway.Described induction pathway is be applicable to being fed to explosive motor 10 from the air air
Cylinder in.Described exhaust pathway is be applicable to obtaining aerofluxus from explosive motor and inciting somebody to action after processing aerofluxus
Aerofluxus is taken out from air system.Air aerating device 12 is positioned in the induction pathway of explosive motor.As before
Mentioning, described air aerating device 12 is supercharger.Described supercharger is received air and makes this air increase
Press, i.e. increase air pressure, and the air of this supercharging is provided in the cylinder of electromotor.According to these public affairs
Another embodiment of the explosive motor opened is two cylindrical type engine.In two cylindrical type engine, empty
The position of all parts of gas system and orientation can keep identical.Another one according to explosive motor is implemented
Example, air system also can have exhaust gas recirculatioon path.In this embodiment, air aerating device 12, i.e.
Supercharger is positioned at the downstream of the part of induction pathway, wherein aerofluxus is led back in air inlet.
Also disclose a kind of method operating explosive motor 10.Explosive motor 10 include induction pathway and
The air aerating device 12 being positioned in induction pathway.Explosive motor 10 is received from being positioned in induction pathway
The air inflation of air aerating device 12.The method of this operation explosive motor is characterised by so that internal combustion
Electromotor 10 is applicable to receive the air inflation of 200-800mbar scope under the full range of speeds of electromotor.?
Air inflation in 200-800mbar scope can explosive motor 10 at full capacity, sub-load and low
Receive under load operating region.The probability providing the air inlet of above-mentioned scope to inflate is important, because this meeting
The optimal value of permission compression ratio in single air-cylinder type and two air-cylinder type explosive motors.This compression ratio guarantees
The increase of robustness higher in Abgasgesetz and therefore power.The air in above-mentioned scope can be provided to inflate
Another one advantage be to use simple mechanical supercharger without other additional requirements.
The work of described supercharger 12 and supercharger 12 can be implemented in a variety of ways.Real according to supercharger
Executing an embodiment of mode, described supercharger can be driven by explosive motor self.Described supercharger is also
Can have bypass trap, it can be with Mechanical course or electric control to open or close so that allows or does not permits
Permitted air inflation and be sent to explosive motor 12.According to another embodiment of supercharger embodiment, this increasing
Depressor can be driven by the battery electric power of vehicle.This embodiment of supercharger allows bigger degree of freedom
Supercharger runs, because supercharger runs does not relies on engine speed.The independent operating of this engine speed
Also allow for supercharger to need not run at part load thus saved the energy.
It is understood that the embodiment described in foregoing specification is only exemplary, and it is not intended to
The scope of the present invention.Other amendments in a lot of such embodiments and in the description embodiment described
It is conceived to change.The scope of the present invention is only limited by the scope of claims.
