EU Directives Opel Vivaro A

General

Directive 70/220/EEC, last amended by Directive 2003/76/EC, concerning measures for the prevention of air pollution from motor vehicle emissions.

Directive 96/96/EC, last amended by Directive 2003/27/EC, concerning the technical monitoring of motor vehicles and motor vehicle trailers.

The purpose of the current Directives, is the maintenance of low emission levels during the entire service life of motor vehicles, by means of regular exhaust gas emissions tests and to ensure that the vehicles mainly responsible for the pollution are taken out of circulation for that period of time during which they are not properly maintained.

Several member states have issued their own regulations concerning exhaust gas emissions tests for light motor vehicles (especially passenger vehicles), which are more stringent than the EC Directive 96/96/EC.

For Diesel Engines:

For self-ignition engines, the smoke opacity measurement suffices as an indicator of working condition of the vehicle with regard to exhaust emissions.

For Petrol Engines with On-Board Diagnostic System (OBD):

The measurement of carbon monoxide emissions from the exhaust system at increased idle speed suffices as an indicator of the working condition of the vehicle with regard to exhaust emissions.

Reading out the OBD fault memory when checking the correct function of OBD system, suffices as an alternative to the CO measurement at idle speed.

On-Board Diagnostic System (OBD)

The OBD system is a diagnostic system fitted to a vehicle for the purpose of monitoring emission-related components. With the help of codes stored in the computer, it is able to display malfunctions (such as a deterioration in catalytic converter efficiency, the occurrence of burn misfires, failure or reduced performance of oxygen/lambda sensors, fuel injection system, etc) and their most likely cause. The onboard diagnostic system is also known as EOBD or EURO-OBD in Europe.

"Malfunction" or "Malfunction Indicator" (= MI) denote a visual (lamp = MIL) or acoustic signal which warns the driver of the vehicle quite clearly that there has been a malfunction in an emission-related component connected to the OBD system or within the OBD system itself.

Motor Vehicles with Self-Ignition Engines (Diesel Engines)

To measure smoke opacity, the engine speed is increased quickly with the transmission in neutral (no load), i.e. the engine is accelerated from idle to cut-off speed.

The absorption coefficient must not exceed the following values:

• Naturally aspirated engines: 2.5 m -1
• Turbocharged engines: 3.0 m -1

or corresponding values when using a tester of a type not used during allocation of the EEC type approval.

Note. Adam Opel AG has determined its own reference values using suitable testers and measurement procedures. These special limit values are listed in the tables and are applicable.

The EGE directive makes provision for extended tolerances for road traffic vehicles. Therefore, the specifications for diesel engine speeds and smoke density limit values differ with respect to type test values and EGE values. This is necessary in order to take account of normal wear and distance driven:

All values specified in this brochure are the EGE test values.

Petrol Engine with OBD

Directive 96/96/EC petrol (2001/9/EC test with OBD).

On vehicles with OBD, the correct function of the OBD system is ascertained through a readout of OBD data instead of a gas measurement at idle speed.

Diesel Engine

Directive 96/96/EC diesel (2003/27/EC smoke test).

Diesel OBD

All diesel automobiles which were type-tested in the calendar year 2003 have OBD except the Zafira (M1), Corsa-C (M1) and N1-versions of the Corsa-C / Combo.

All diesel passenger vehicles which are approved from 01.01.2004 onwards will have OBD.

The delivery van versions (N1) of the models

do not have an OBD system.

Note. A new exhaust gas emissions test for diesel vehicles with an OBD system is currently under development.
