THE RACE IS ON

摘要

Compression ignition engines account for a huge amount of the European market. The technology's fuel efficiency and low-carbon emissions, compared with those of gasoline engines, appeal to consumers. And in a market where CO_2 legislation has such a huge impact, this popularity is not surprising. But as emissions legislation develops and the importance of CO_2 begins to balance more evenly with that of other emissions such as NOx and particulates, engineers developing the technology will face an increasing challenge. Audi has a long history of developing compression ignition systems, and not just for passenger vehicles, The firm has won several motorsport titles using diesel engines.
