AIRPATH CALIBRATION

1 INTRODUCTIONThe aim of these tests was to calibrate the "Intake Air System".The target of the Intake System (INSY) is to coordinate the air flow controlling components (throttle and variable intake manifold) and to predict the air mass flow behaviour.With Systems like this, equipped with a manifold pressure (MAP) sensor, the mass air flow is not directly measured but only calculated out of the air density, it strongly depends on the knowledge of the air temperature in the manifold. Any deviations from the temperatures valid during the calibration of the engine have to be compensated.

3 RESULTS & METHODS

3.a AMP acquisitionDue to non presence of AMP sensor, the ambient pressure is measured by MAP sensor in the two following cases:

At the first tooth detection, AMP = MAP At full load (naturally aspired engine) where AMP = MAP – pressure loss through the air

cleaner.

AMP learning activation was calibrated for: C_AMP_HYS = 2 hpa of difference in order to enable learning at Full load conditions. C_AMP_MIN = 500hpa C_AMP_MAX = 1200hpa C_N_AMP_AD_MAX = 4200rpm C_N_AMP_AD_MIN = 1600rpm IP_TPS_AMP_AD_MAP_MAS_MIN_1 comes from the previous calibration

3.b Pressure loss through the air cleaner determination:

The aim of this test was to model the pressure decrease between ambient pressure AMP and the pressure upstream the throttle PUT due to air filter and ducts in the air cleaner and the air intake.

This table was calibrated, using the difference between AMP bench measurement and the MAP system measurement, on the full load points at different engine speeds between AMP acquisition limits of C_N_AMP_MIN and C_N_AMP_MAX.

The VS effect was not calibrated at engine bench so the values were constant function of vehicle speed.

Pressure loss through the air cleaner:

3.c TIA_THR / T_OIL / TAM

According to the air temperature sensor position inside the intake manifold, it is expected that TIA_IM and TIA_CYL are comparable to the measured air temperature. Therefore TIA_IM and TIA_CYL are set equal to TIA, which normally based on the measured TIA_MES value.So the TIA configuration was TIA = TIA_IM = TIA_CYL.

The calculation of TIA_THR is made from TIA, by taking into account the influences of:1. The mass air flow through the throttle (mapped via MAF_THR_STK_TIA, N_32)2. The manifold wall temperature (mapped via TIA, TOIL)

Exhaust gas recirculation and canister purge effects are not taken into account.

IP_TIA_THR table was calibrated using volumetric efficiency measures with VIM off, using bench measures of inlet temperature near throttle compared to inlet manifold temperature.

3.d VOLUMETRIC EFFICIENCIES

The aim of the test was to calibrate the volumetric efficiency slope and offset in two VIM positions so that the linear model best fits the reality of the actual engine. Because in the Intake Manifold Model, the mass air flow into the cylinder is modelled as a linear (volumetric efficiency) depending on the intake manifold pressure. These coefficients depend on the engine speed and then are valid for a real linear relation between the MAF_CYL and the MAP in regular conditions. In steady state and without EGR or canister purge, MAF_CYL=MAF_THR.

On the Proton engine configuration, four tables were used to the volumetric efficiency calibration:VIM_OFF:IP_EFF_VOL_OFS_3[0][0][0]: volumetric efficiency slope in VIM position 0IP_EFF_VOL_SLOP_3[0][0][0]: volumetric efficiency offset in VIM position 0VIM_ON:IP_EFF_VOL_OFS_3[1][0][0]: volumetric efficiency slope in VIM position 1IP_EFF_VOL_SLOP_3[1][0][0]: volumetric efficiency offset in VIM position 1

The table change between the two VIM states (OFF / ON) is made by the index STATE_ACR_EFF_VOL_CLC.

To calibrate these tables, were done measures of System MAP and Bench MAF at 300mbars (low load), at 600mbars (part load) and at Full Load, on engine speeds corresponding to table breakpoints and on both positions of VIM.Slope and offset of resultant lines were calculated via Excel function at each engine speed breakpoint of volumetric efficiency maps.Then the results were reported in tables.

3.e Eff_vol_flow_cor

Because of no linearity of the air path model and to avoid so important MAF error the model eff_vol_flow_cor was calibrated from 1000rpm to 2400rpmIt was normally used on turbo engine.

Configuration: Lc_prs_ex_swi = 1 Ip_prs_ex = 1013mbar ip_eff_vol_vo_cor_2[0] = 1 ip_eff_vol_vo_cor_2[1 = 1 ip_eff_vol_prs_ex_cor_1[1] = 0

From data of a complete engine characterization, ip_eff_vol_prs_ex_cor_1[0] was tuned to minimize MAF error from 1000rpm to 2500rpm.

3.f REDUCED AREA

This test allows calibrating the basic reduced area which represents the real area air flow.On the Proton application, only the throttle opening section was considered, then only the table IP_AR_RED_THR was calibrated.

So to calibrate this table, sweeps were done on several engine speeds at iso TPS values, and for all throttle position breakpoints, the table was readjusted to reduce the variables AR_RED_DIF_REL and PUT_MDL_DIF_REL until 0.Then the map IP_TPS_SP_MDL_BAS is an inversion of the table IP_AR_RED_THR.See graph page 31.

IP_AR_RED_THR and IP_TPS_SP_MDL_BAS final tables:

4 CONCLUSIONCalibrations were correctly performed without any problem.

Different tables validations revealed that maps were correctly calibrated, with global TIA_THR error below 3°C and global MAF error between - 5% (low rpm, part loads) and 3%.

The volumetric efficiency were also reworked on the breakpoints 800 rpm, 1000 rpm, 1200 rpm, 1600 rpm, 2400 rpm, 5400 rpm & 5800 rpm in order to minimize a so important error at low MAF (<200mg/strk). Slope and the offset were changed on the table to have better accuracy at low MAF and keeping a correlation (MAF system / MAF bench) acceptable for higher MAF. This change explains the area at low rpm & part load where MAF_DIF reach -5% during the first validation.

To correct this error, eff_vol_flow_cor was activated and tuned from 1000 to 2400rpm. This function permits to a supercharger engine to model MAF as a curve instead of a line, function of the ratio MAP / PRS_EX. and engine speed. In our case PRS_EX is fixed to 1013This calibrations was validated with the last engine characterisation, EDTR145 TEST 17, results were correct, see to the graphs page 11

For the table of IP_AR_RED_THR, original breakpoints at 13% and 17% of TPS_SEG were changed for breakpoints 30% and 40 % in order to be more accurate at high load and high rpm.
