Regulatory
Regulations limiting emissions and requiring improved fuel economy for diesel-fueled internal combustion engines used in on-road vehicles are today's main driver for changes in diesel engine and emissions system hardware. These hardware modifications, along with the need to improve fuel economy, subsequently drive changes in diesel engine oil performance.
Important regulations are posted here to give the reader a basic understanding of the regulatory driving forces behind the rapid changes in diesel engine and emissions system technology and the push to improve fuel economy.
