| Objectives | The objective of this research was to review the engine management systems used on heavy-duty diesel engines and to provide a comprehensive engineering assessment of the potential for those systems to be equipped with an embedded activity recorder. This assessment included technical feasibility, system security and cost implications. | |
| Abstract | Compliance of an engine to the regulated emissions standards is assessed using a defined drive cycle. It is theoretically possible for the development of technical strategies designed for heavy-duty diesel engines to pass the test cycle but deliver improved fuel efficiency when in use – in response to consumer pressure. This would be at the expense of significant increases in regulated pollutants. Research indicates that for these engines, a fuel consumption reduction of 5–10%can result in a typical penalty of a 25–50% NOx increase. A solution to this could be to require that future engine management systems could be interrogated by national authorities to identify in-service engine maps. This would enable detection of any cycle-beating strategies. | |
