CONCERTO EVALUATION TOOL – CET

Project Definition Data Acquisition Data Storage Data Exploitation

Where are my Data?

I have to finish my

report on time

One Engine

Many variants


CONCERTO EVALUATION TOOL – USE CASE

Mail from Calibration Engineer:

Something has come up in my calibration project and I need to search through some old

data.

I particularly need to find some data (amongst gigabytes) where:

• Ambient temperature is <0ºC

• DPF regeneration mode is active

Once I've found the files I need to study the combustion stability at idle.

What would be your approach to solve this problem ?



1. Go to the project drive, local hardware, ask to your colleagues to select some files where our event could have occurred.

2. Open manually file per file in MDA or Concerto

3. Go through the complete measurement file

4. Hope to find something

Looking for a needle in a haystack!


CONCERTO EVALUATION TOOL – CET

Live demonstration



Common Approach CET Approach

1st step: ~1min

• Open one file in MDA • Select channels • Load file

2nd step: ~5min

• Adjust scale• Go trough all the file (30min recording)• Located the event • Copy to a PPT

Repeat 1st and 2nd step for 30 files

Total time: 6min*60 = 6h!

Probability of missing info = High!

1st step: ~5min• Open CET• Select output channels • Define Event • Select files/folder

2nd step: ~30sec• Run CET• Report Generation

Probability of missing info = Null!

Total time: 5min+30sec = 5,5min


CONCERTO EVALUATION TOOL – BENEFITS

No matter the amount of data,

CET will take care of them

CET will be your Ally for solving

problem

CET will allow you spend more time to

calibrate

Focus on Calibration task

Step 3: Identification of normal windows and trip completeness

If the specified minimum requirement of 50% is not met, the

upper positive tolerance tol1

may be increased by steps of 1% until the 50% of normal

windows target is reached. When

using this mechanism, tol1 shall never exceed 30%.

AGENDA



RDE – REAL DRIVING EMISSIONS

Real Driving Emissions

• Emission testing under normal conditions of use in real world driving.• Portable Emission Measurement System (PEMS)

• CO2, CO, NOx and PN• Exhaust flow rate, Speed and GPS data.

RDE Test

• 90 to 120 min test time• 34% City (<60km/h) | 33% rural (60 ... 90km/h) | 33% Highway (>90km/h)• 145km/h max speed (extended range up to 160km/h)• Dynamic within certain range. Dynamic=a.v• Realistic vehicle load and AC operated as under normal driving• Cold start is measured, but not included in result calculation

Ambient conditions

• Temperature between 0°C to 30°C (extended range -7°C to 35°C)• Altitude up to 700m (extended range up to 1350m)• Humidity as it is, but no NOx humidity correction like in lab-tests

Limits and Result calculation

• Limits are based on the laboratory limits multiplied by the so called „Conformity Factor CF“. CF for NOx phase in from 2.1 to 1.5 and CF for PN under discussion

• 2 Complex result calculation options, EMROAD (JRC) or CLEAR (TU-Graz)


RDE – DRIVERS AID APPLICATION

Challenging to ensure that all RDE criteria are fulfill while driving

More than 30% of RDE test are not valid (source: AVL PTE)
