Description
Technical field
The present invention relates to technical field of engine control, and in particular to a kind of verification side of the pressure-resistant performance of automobile booster
Method.
Background technology
For engine with supercharger, larger intake resistance, engine on the one hand can be made to lack enough air completely burneds, drawn
The problems such as fuel economy is deteriorated, excessive and power of discharging fume reduces is played, on the other hand can make the reduction of booster operational efficiency, extend
Combustion duration, influence complete machine combination property.In addition, intake resistance is more than the limiting design value of booster, sealed-bearing can be destroyed
Pressure balance, cause booster oil leak.
Detection for automobile booster at present is to be carried out after vehicle assembles by way of experiment, once detection
Go wrong, it is necessary to which the vehicle just assembled, which disassemble, to be solved the problems, such as, detection efficiency is relatively low, and cost is higher.
The content of the invention
It is an object of the invention to provide a kind of method of calibration of the pressure-resistant performance of automobile booster, this method can meet
Theoretical optimum combination is filtered out in multigroup scheme of condition, for designer's decision references.Without when the complete vehicle test stage
The relation of booster voltage endurance capability and vehicle gas handling system resistance could be detected.
In order to solve the above technical problems, a kind of method of calibration of the pressure-resistant performance of automobile booster disclosed by the invention, it is wrapped
Include following steps：Step 1：From turbocharged engine system obtain i kind boosters, wherein i be >=1 natural number, every kind of supercharging

J kind gas handling system information is obtained in system, wherein, every kind of gas handling system information includes gas handling system resistance pjWith air filter resistance
Surplus Δj, and j is >=1 natural number, then it is gas handling system resistance p to have every kind of gas handling system Resistance Valuej+ air filter resistance surplus
Δj, then j kinds gas handling system Resistance Value be expressed as set B=(p1+Δ1,p2+Δ2,…,pj+Δj), Sample Storehouse is established to hold
Receive set A and set B；
It is as follows to establish verification functional relation：
f(Pi,pj,Δj)=Pi-(pj+Δj), wherein Pi∈ A, (pj+Δj)∈B；
In formula, each value P in set AiOne by one with each value (p in set Bj+Δj) calculating verification is carried out, wherein,
Booster to be verified combines shared (i*j) kind with gas handling system；
Step 2：Establish correction verification module, setting f (Pi,pj,Δj)>0 rule passed through as verification；
As f (Pi,pj,Δj)<0, then vehicle air inlet drag overall exceedes the resistance to negative pressure ability of booster, and booster has leakage
Risk, verification do not pass through；
As f (Pi,pj,Δj)=0, belongs to theoretical critical fire area state, and verification does not pass through；
As f (Pi,pj,Δj)>0, then verification passes through, it is determined that booster corresponding to selected can match the vehicle, and remembers
Record f (Pi,pj,Δj)>Data splitting corresponding to 0；
Step:3：The process of repeat step 2, cycle calculations, each booster in Sample Storehouse is combined with gas handling system
Verify one by one, until all boosters and the gas handling system combination verification of Sample Storehouse finish.
Beneficial effects of the present invention：
Because intake resistance is more than the limiting design value of booster, sealed-bearing pressure balance can be both destroyed, causes booster
Oil leak, air input of engine by air can be reduced again, influence the economy and dynamic property of engine.Therefore, designed in vehicle gas handling system
At initial stage, booster selecting type scheme is judged using the present invention, by establishing booster stem seal design limit value, air cleaner
Functional relation between resistance and gas handling system resistance three, whether booster meets vehicle requirement selected by judge, avoids designing
Middle and later periods, which just finds that booster oil sealing limit value is less than normal by complete vehicle test, causes Leakage to be done over again again to be delayed cycle and fund
Waste, improve design efficiency and accuracy rate.In addition, it can be sieved in multigroup booster/gas handling system combination for meeting condition
Select theoretical optimum combination, designer is as reference, and considering cost and performance requirement, so that it is determined that suitable design
Scheme.The method of calibration realize it is simple and direct, it is easily operated.
Brief description of the drawings
Fig. 1 is the logical flow chart of the present invention；
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail：
The method of calibration of the pressure-resistant performance of automobile booster of the present invention, it is characterised in that comprise the steps of：
Step 1：From turbocharged engine system, (turbocharged engine system includes a variety of different manufacturers, various models
Booster information) in obtain i kind boosters, wherein i is >=1 natural number, and the oil sealing pressure design limit value of every kind of booster is
