A technical summary of Euro 6/VI vehicle emission standards

Limits on particle mass emissions for diesel cars have nonetheless been reduced by large amounts since the Euro 1 standards were introduced. The Euro 6 particle mass limits for diesel cars represent a reduction of 96% from Euro 1 limits. The particle mass limits are now so low that measurement accuracy and sensitivity are an issue, which has prompted the introduction of limits on particle
