Description
Technical field
The invention belongs to running noise control technology fields, and in particular to reduce the method and dress of engine combustion noise
It sets.
Background technique
With progress of the epoch, the surrounding enviroment of running car constantly change, road surface is more and more flat, and speed is increasingly
Height, noise problem gradually cause everybody attention and attention.Whether influence or vehicle of the pass-by noise to the periphery inhabitation people
Influence of the interior noise to passenger, all makes people have strong wish to go to improve it.
Correspondingly, in order to solve this problem, government has put into effect the regulation being increasingly stringenter, to control generation when automobile passes through
Noise.But this method is palliative, need to also reduce noise from automobile.
Noise source in vehicle traveling process mainly includes engine, loudspeaker, tire etc., and engine noise in occupation of
Highest contribution amount (55% or more).Try to reduce engine noise, is to improve the most effective approach of Noise Generated by Running Vehicles.
There are mainly three types of types for the noise that engine issues: combustion noise, mechanical noise and aerodynamic noise.Burning is made an uproar
Sound and mechanical noise are outwardly radiated by engine, and aerodynamic noise is mainly generated in air inlet and exhaust process,
Directly to atmospheric radiation.Wherein, combustion noise is in combustion mixture volumetric combustion, because cylinder interior gas pressure steeply rises punching
Each component of motivation is fired, is allowed to vibrate and the noise of generation, is the Main Noise Sources of diesel engine.Cetane number in diesel oil does not conform to
Suitable or injection time excessively shifts to an earlier date, and engine operation can be caused rough, increased dramatically noise.
The Chinese patent that application publication number is CN104564392A discloses vehicle when a kind of reductions vehicle gives it the gun and makes an uproar outside
The method of sound, this method are configured the acceleration of friction speed section vehicle, to limit adding during vehicle gives it the gun
Speed reduces engine noise so as to reduce engine speed when vehicle gives it the gun, and then reduces vehicle and accelerate row
Pass-by noise when sailing.However the method has the disadvantage that
1. the oil spout of engine be generally divided into it is pre- spray, main jet and after spray three phases, the adjustment that this method passes through distributive value
It is related to the reduction of engine speed, is to be adjusted to the oil mass in main jet stage, and main jet stage oil mass accounts for total fuel injection quantity
95% or more, any slight adjustment will to the entire oil spout stage distributive value of engine generate large effect, in this way tune
Whole excessively extensive, the overall performance change for adjusting to engine is larger, is unfavorable for the intense adjustment of engine performance
And control.
2. this method causes the reduction of engine speed by adjusting the distributive value in entire oil spout stage, and then engine
Output torque changes correspondingly, and final result influences the performances such as dynamic property and the economy of engine, especially fixed to accelerate
The reduction of section engine section end revolving speed will lead to engine power performance reduction, may cause vehicle under the bad working environments such as climbing
Traveling it is difficult.
3. carrying out the control of distributive value based on vehicle speed information, the practical driving habit of driver is not considered, and driver
Driving habit is often very big on the influence of engine actual working condition, such as under same speed, adds and subtracts throttle or steps on suddenly violent
The actual distributive value of engine is different under accelerator releasing, engine may be caused to work roughly due to driver's driving habit
The case where occur, there are gas pedals to step on other influence factors such as speed when actually controlling distributive value for this method, is not easy
Control.
Summary of the invention
The purpose of the present invention is to provide the method and devices for reducing engine combustion noise, to solve in the prior art
The practical driving habit of driver is not considered and the case where engine works roughly occurs, causes that starts combustion noise big to ask
Topic.

State the corresponding relationship that Engine Injection Mass relationship is pressure information and the smallest pre- distributive value of combustion noise；
According to pre- distributive value, controls engine and carry out pre- oil spout movement.
Further, the pre- oil spout magnitude relation of the engine of the storage are as follows:
Wherein, Q is pre- distributive value, and P is pressure information and P1< P2< P3< ... < Pn-2< Pn-1< Pn< Pmax, Q1、Q2、
Q3、...、Qn-1、Qn、QmaxPre- oil spout magnitude respectively corresponding with pressure information.
A kind of device of reduction engine combustion noise of the invention, including acceleration mode detection unit, pressure sensor,
Processor and action control unit；
The acceleration mode detection unit is for detecting whether vehicle is in acceleration mode；
The pressure sensor is used to acquire the pressure information of gas pedal receiving；
The processor is used for the pre- oil spout magnitude relation of engine according to storage, obtains corresponding with current pressure information pre-
Distributive value；Wherein, the Engine Injection Mass relationship is the corresponding relationship of pressure information and the smallest pre- distributive value of combustion noise；
The action control unit is used for according to obtained pre- distributive value, and control engine carries out pre- oil spout movement.
Further, the processor is ARM.
Further, the action control unit is engine electric-controlled system ECU.
Further, the pre- oil spout magnitude relation of the engine of the storage are as follows:

Q3、...、Qn-1、Qn、QmaxPre- oil spout magnitude respectively corresponding with pressure information.
Beneficial effects of the present invention:
The pressure information born the present invention is based on gas pedal is obtained according to the pre- distributive value characteristic relation of the engine of storage
Pre- oil spout movement is carried out to pre- distributive value corresponding with current pressure information, and then according to the pre- distributive value control engine.This
Invention judges the driving intention of driver, the pressure that comparison current throttle pedal is born according to the pressure information that gas pedal is born
Force information and the pre- distributive value characteristic relation of the engine of storage, are adjusted under engine accelerating mode according to the intention of driver in real time
The whole and pre- distributive value of control, ensure that the ignition delay period of engine main injection under giving it the gun operating condition is most short, avoids running over
The case where engine as caused by driver's driving habit works roughly in journey, the burning for effectively reducing engine are made an uproar
Sound realizes that the synchronous of the inside and outside noise of vehicle reduces when vehicle gives it the gun, and improves the comfort of vehicle.
The present invention only adjusts the distributive value that engine sprays the stage in advance, since the specific gravity that it accounts for entire oil spout stage distributive value is non-
