Procedures & Best Practice

Best Practice Guideline to download

According to an estimate of OECD, particles emitted by diesel combustion engines cause only in Germany every year more than 40,000 premature deaths. Since 1982 a highly effective technology is available to reduce this emission. Today more than 100 million filters are deployed in road vehicles, construction machines, forklifts, etc. The retrofitting cost is less than a tenth of the health costs.

The attached "Best Practice Guideline" gives a comprehensive overview about the most relevant tasks and technology questions. Amongst others, readers will find information concerning the following topics:

- Health problems caused by diesel combustion engines without filter systems
- Vehicle types concerned
- Technology of filter systems
- Retrofitting
- Operation, diagnosis, and maintenance of filter systems
