Diesel Engine Emissions Test Through EU5

Special tools and workshop equipment required

Emissions Testing Station L :VAS 7320 A

NOTE:

The following description is based on vehicles that are equipped with "On Board Diagnostics", OBD.

OBD monitors all components and partial systems that influence the emissions quality.

An emissions test is only possible when all units of Emissions Testing Station are connected properly according to operating instructions and are connected to each other.

All procedures being performed are displayed on the Emissions Testing Station.

Test Requirements

All of the test conditions and data required for the emissions test are on the emissions testing data sheet for the corresponding engine.
Automatic transmission: selector lever in "P".
Manual transmission: gearshift lever in neutral.
Parking brake applied
12V battery completely charged (too low of a charge may increase the idling speed).

-- Perform emissions testing according to instructions in the display.

Vehicle Data Input

-- Enter the following data:

License plate number
Key number
Vehicle Identification Number (VIN)
Fuel type
Odometer reading

The following vehicle data can be found in the certificate of registration part 1:

License plate: "for example, WOB-HH 1234"
Emissions key number. "Field 14.1 (Code for field 14)"
Vehicle manufacturer: "Field 2,", "Field 2.1 (Code for field 2)"
VIN: "Field E"
Type and version "field D2 (type only)", "Field 2.2 (Code for field D.2)"
Nominal speed: "field P4"

Emissions Test Specified Data Input

Specification data may be entered differently:

1. Manually
2. Using automatic data transfer from the Emissions Testing Station database

Manual Emissions Test Specified Data Input:

NOTE:

The necessary emissions test conditions and data for the corresponding engine can be found here. Refer to Data sheets for exhaust emission test .

The nominal speed is located in field P4 of the certificate of registration part 1 or in field 7 of the vehicle registration and must always be manually entered.

For an idling engine speed limitation that cannot be deactivated, enter the value 2500 ± 200 RPM in the speed regulation field and 2500 in the speed for conditioning field.

-- Follow the instructions on the display for manual data input.

-- Enter the indicated values on the emissions testing data sheet "test values for the emissions test" on the display in the following sequence:

Speed for Conditioning
Number of Throttle Bursts for Conditioning
Engine Oil Temperature (Minimum Value)
Select Method for Measuring Engine Oil Temperature
Idle Speed
Speed Regulation
Nominal speed (certificate of registration part 1, vehicle registration)
Speed Regulation Measured Time (1 second)
Emissions Sticker Value. Refer to DIESEL ENGINE EMISSIONS TEST THROUGH EU5 => .
Select Sensor Type (Sensor Number)
Select Measuring Mode
Measurement Time Amount

NOTE:

During the practical emissions test of Euro 5 vehicles, the technician is required to use the vehicle-relevant emissions sticker value on the type plate as the emissions test threshold.

If there is not an emissions sticker value, then the turbidity value given by the manufacturer on ELSA must be used.

If there is not a emissions test sticker value or a manufacturer value for the vehicle, then the legal turbidity value (2.5 m (8.2 feet) ^-1 or 1.5 m (4.9 feet) ^-1 depending on the registration date) must be used.

The nominal speed can only be manually entered.

If the turbidity value of Euro 5 vehicles on the emissions testing data sheet differs from the emissions sticker value on the type plate, then the value from the emissions sticker must be entered manually.

Visual inspection

-- Visually inspect all emissions-related components.

-- Check the exhaust system for completeness, leaks and damage.

Procedure

-- Follow the instructions on the Emissions Testing Station.

Evaluation

NOTE:

If the emissions test was performed with the idling engine speed limitation, a note will appear in the log "speed regulation <90 % of nominal speed (idling engine speed limitation)."
