The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.The present embodiment is with technical solution of the present invention
Premised on implemented, the detailed implementation method and specific operation process are given, but protection scope of the present invention is not limited to
Following embodiments.
Embodiment
The present embodiment proposes the petrol engine intake system and air input control method of a kind of not throttle body, passes through control
Air inlet switching valve 5 processed, variable valve timing, lift range variable and turbocharger 1 exhaust gas by-pass valve 2, reach to air inlet
The control of charge.Specific gas handling system schematic diagram is as shown in Figure 1.
A kind of petrol engine intake system, including electronic control unit, pipeline, turbocharger 1 and changeable air valve, changeable air valve packet
Inlet valve 3 and exhaust valve 4 are included, turbocharger 1 includes exhaust gas by-pass valve 2, and system further includes air inlet switching valve 5, air inlet switching
Valve 5 is placed in the pipeline between 1 air inlet of turbocharger and inlet valve 3, electronic control unit control air inlet switching valve 5 realize two kinds into
The switching of tolerance mode, when work, air passes sequentially through 1 air inlet of turbocharger, air inlet switching valve 5 and inlet valve 3 and enters
Cylinder 9, cylinder 9 is discharged by exhaust valve 4 in exhaust gas, and gasoline is discharged by exhaust gas by-pass valve 2 or 1 gas outlet of turbocharger
Machine.
Pipeline forms first pipe branch 6 and second pipe branch 7 between 1 air inlet of turbocharger and inlet valve 3, the
One pipeline branch, 6 input end and 7 input end of second pipe branch are connect with 1 air inlet of turbocharger, and first pipe branch 6 goes out
Mouth end and 7 outlet end of second pipe branch are connect with inlet valve 3.
6 diameter of first pipe branch is greater than 7 diameter of second pipe branch.
First pipe branch 6 is arc.
Air inlet switching valve 5 is three-way valve, and three-way valve first outlet is connect with 6 input end of first pipe branch, threeway
Valve second outlet is connect with 7 input end of second pipe branch.
Three-way valve is L-type three-way valve.
1 air inlet of turbocharger is connect with air inlet switching valve 5 by intercooler 8.
A kind of air input control method using petrol engine intake system, using air inlet switching valve 5, variable valve timing,
The combination of lift range variable and exhaust gas by-pass valve 2 controls air inflow.
The each actuator of gas handling system and control strategy are as follows:
(1) 5 control strategy of air inlet switching valve
When gasoline engine works, there are two positions for air inlet switching valve 5.As shown in Fig. 2, when gasoline engine work in idling or compared with
When Smaller load, larger charge is not needed, at this time 1. air inlet switching valve 5 is in position, has completely closed first pipe branch
6, second pipe branch 7 is opened, air inflow is controlled；When gasoline engine needs to export larger torque, then more air inlets are needed
Amount, at this time 2. air inlet switching valve 5 is in position, has fully opened first pipe branch 6 and has simultaneously closed off second pipe branch 7,
Restriction loss is small at this time, can guarantee larger air inflow.
Gasoline engine overwhelming majority operating condition uses first pipe branch 6, and the presence of second pipe branch 7 is to meet
Small air inflow demand.
(2) variable valve timing (VVT) control strategy
Variable valve timing is to change valve-control by rotation camshaft；Miller cycle gasoline engine uses inlet valve
3 modes early closed control air inflow, in order to meet the air inflow demand of different operating conditions, generally mutually to tie with variable valve timing
It closes.
As shown in figure 3, not needing too big air inflow when compared with Smaller load, the early pass angle of inlet valve 3 is bigger at this time, and valve shifts to an earlier date
Closing can make expansion ratio be greater than actual compression ratio, and burnt gas sufficiently does work to improve fuel economy；In larger load,
Larger air inflow is needed, early pass angle is smaller for valve at this time, increases inlet period window.
(3) lift range variable (VVL) control strategy
Lift range variable is realized by switching different cam profiles.
As shown in figure 4, under small load condition, using small lift cams, to keep air inflow less；In high load working condition
Under, using long-nose cam, volumetric efficiency is improved, to meet power demand.
(4) exhaust gas by-pass valve 2 (EWG) control strategy
Exhaust gas by-pass valve 2 is the discouraged control valve of turbocharger 1.
As shown in figure 5, not needing larger boost pressure when load is smaller, exhaust back pressure can be reduced by opening by-passing valve, from
And pumping loss is reduced, improve fuel economy；When power demand is larger, the adjustable extent of VVT and VVL are had exceeded, at this time
The intervention for needing turbocharger 1 increases charge using exhaust kinetic energy to plenum, improves gasoline engine power.
The present embodiment propose petrol engine air admission amount control method mainly include to air inlet switching valve 5, variable valve timing,
The control of lift range variable and exhaust gas by-pass valve 2.Different load is needed through different actuator combination control.Fig. 6 is logical
Cross the combination control tactics that GT-POWER is emulated.
(1) low speed small load condition
It needs to control air inlet switching valve 5 at this time, using second pipe branch 7, reduces throughput；Main control inlet valve 3
It is early to close angle, thus to adjust required power output；It is secondary to use smaller lift cams and open exhaust gas by-pass valve 2.
(2) load condition in
Mainly control inlet valve 3 is early at this time closes angle and lift range variable, to reach the control to air inflow；Air inlet at this time
Switching valve 5 switches to first pipe branch 6,2 standard-sized sheet of exhaust gas by-pass valve, to reduce pumping loss.
(3) high load working condition
Main control exhaust gas by-pass valve 2 and the early pass angle of inlet valve 3, to reach the control to boost pressure and charge flow rate；
Using long-nose cam, air inlet switching valve 5 switches to first pipe branch 6.
Specifically, obtaining in average effective cylinder after pressure and revolving speed, pressure and revolving speed in average effective cylinder are judged:
Situation one: if pressure is between 0kPa-500kPa in average effective cylinder, while revolving speed minimum value is in 0r/
Between min-1500r/min and revolving speed maximum value is between 3500r/min-4500r/min, and electronic control unit is by adjusting air inlet
Switching valve 5 and variable valve timing control air inflow；
Situation two: if pressure is between 0kPa-1500kPa in average effective cylinder, while revolving speed minimum value is in 0r/
Between min-1500r/min and revolving speed maximum value is between 5500r/min-6500r/min, removes situation one, electronic control unit
Air inflow is controlled by adjusting lift range variable and variable valve timing；
Situation three: if pressure is between 1000kPa-2500kPa in average effective cylinder, while revolving speed minimum value is in
Between 0r/min-1500r/min and revolving speed maximum value is between 5500r/min-6500r/min, removes situation two, automatically controlled list
Member controls air inflow by adjusting exhaust gas by-pass valve 2 and variable valve timing.
Power control unit is ECU, is controlled in the same traditional gas handling system of power control unit control 5 mode of air inlet switching valve
Electronic throttle method.
