Description
Technical field
The present invention relates to Vehicle Turbocharged engine component, be specifically related to the aerofluxus discrimination of a kind of exhaust gas turbocharge electromotor
Pipe.
Background technology
In the face of increasingly serious energy shortage and ecological deterioration problem, oil consumption limit value and Abgasgesetz become more and more stricter
And harshness.Fuel oil consumption and pollutant emission are that main engine plants need reply and consider, it is necessary to meet corresponding laws and regulations requirement.So
And, from another angle, namely the driving angle of passenger car consumer is set out, fuel oil consumption and pollutant emission the two side
Face may not be the factor that they pay close attention to most, and passenger car consumer wishes that the power output of electromotor can be guaranteed even
Higher, it is possible to bring enough Drivings.From the point of view of in terms of these, electromotor is had by relevant laws and regulations and passenger car consumer
Higher requirement, say, that in the case of meet low oil consumption and low emission, the power output of electromotor is also wanted enough
By force.At such multiple pressure with under limiting, engine booster is becoming a kind of technology being generally used, meanwhile,
The concept of " downsizing " and " downspeeding " also by the accreditation of increasing main frame manufacturer and is progressively implemented, but with
The step-down of the reduction of engine displacement, rotating speed, the output of the low side moment of torsion of electromotor is adversely affected, and then has influence on and take advantage of
With the car consumer Driving to car load.In order to improve to a greater degree exhaust gas turbocharge electromotor transient response,
Utilizing exhaust pulse energy as much as possible, exhaust manifold becomes a very important content of electromotor design.
Current exhaust gas turbocharge electromotor, great majority use 4-1 compact exhaust manifold.The row of this form
Gas manifold inevitably results in interfering with each other between each cylinder aerofluxus, and this is the most unfavorable to the utilization of exhaust pulse energy, this
Although kind of a manifold is not known compact, but the use rate of waste gas profit is not enough, the low side especially after engine displacement diminishes, to electromotor
The adverse effect of moment of torsion output is more prominent, simultaneously as aerofluxus is not smooth, the exhaust manifold of this form makes residual gas in cylinder
It is in higher level, has influence on the anti-knock properties of electromotor further, thus the moment of torsion output to electromotor exerts an adverse impact.
For naturally aspirated engine, designer generally uses 4-2-1 type exhaust manifold solve or improve each cylinder
Exhaust interference problem.This 4-2-1 type exhaust manifold ignition order based on electromotor is grouped, and for ignition order is
The four cylinder engine of 1-3-4-2,1,4 cylinders are divided into one group, and 2,3 cylinders are divided into another set.Such meeting in group makes electromotor arrange
Gas is more smooth and easy, can reduce residual gas in cylinder, and then improve the electromotor capability of antidetonance, improves electromotor low side moment of torsion defeated
Go out.But, for exhaust gas turbocharge electromotor, in addition to residual gas the two problem in exhaust interference and cylinder, also want
Taking into account the transient response of electromotor, this just requires that the total measurement (volume) of whole exhaust manifold is the least.
Summary of the invention
It is an object of the invention to for above-mentioned reduction exhaust interference, suppression pinking tendency, promote low side moment of torsion and improvement
Transient response sexual demand, proposes the exhaust manifold of a kind of Vehicular waste gas turbocharged engine: according to engine-firing order handle
Each exhaust branch pipe is grouped, and reduces exhaust interference, improves engine transient and thinks impact.For the same purpose, as much as possible
Reduce the total measurement (volume) of exhaust manifold, the length and layout of each arm do careful considering.4-2-1 type exhaust manifold is used
Solve or improve the exhaust interference problem of each cylinder.Each exhaust branch pipe is grouped according to the ignition order of electromotor, for sending out
Fire order is the four cylinder engine of 1-3-4-2, and 1,4 cylinders are divided into one group, and 2,3 cylinders are divided into another set, and make a wherein cylinder
Manage the gas outlet just to exhaust manifold.Concrete technical scheme is as follows:
The exhaust manifold of a kind of exhaust gas turbocharge electromotor, including first group of exhaust branch pipe, second group of exhaust branch pipe, leads
Stream dividing plate and waste gas outlet, wherein, described first group of exhaust branch pipe and second group of exhaust branch pipe come together in waste gas outlet；Described
