Global concern for a cleaner environment is a fact of life, affecting individuals, commerce and industry.

Many regulations, both global and local, have already been set to control levels of smoke, particulates, NOx, SOx and other pollutants.

EPA Environmental Protection Agency legislation is one example of how limits on particulates and NOx have changed over the years: between 1988 and 2010 the requirements for emission reduction will rise more than 95%.

Regulations are expected to continue to become stricter in the future. We are continuously looking for and developing new technologies to meet these requirements, to ensure environmentally sound operations in terms of low emissions, low environmental impact and sustainability.

The new technology is provided as standard on new engines and can often be retrofitted on older engines, so that they too can benefit from improvements not available when they first entered service.

The many primary and secondary measures available include mechanical modification of engine components, and the modification and tuning of engine parameters.
