Between 1998 and 2006 Cummins shipped more than 570,000 heavy duty diesel engines to car companies without fitting anti pollution equipment.

The equipment known as exhaust after-treatment devices, or ATDs, include catalytic converters and diesel particulate filters.

The settlement requires Cummins to recall around 405 engines which got to the public without the correct ATDs installed.

Cummins, based in Columbus in the US, will pay the penalty and recall 405 engines under a settlement agreed to resolve violations under the Clean Air Act, the US Environmental Protection Agency (EPA) and the Justice Department have announced.

“Reliable and effective pollution control systems are essential to protect human health and the environment from harmful engine emissions,” said Cynthia Giles, assistant administrator for EPA’s Office of Enforcement and Compliance Assurance.

“These requirements are a critical part of EPA’s program to reduce air pollution and secure clean air so that all Americans can breathe easier.”

The settlement was lodged in the US District Court for the District of Columbia and is subject to a 30-day public comment period.
