Lower emissions with Tier 4 engines

2014 Jan 08

Atlas Copco is introducing Cummins Tier 4 Interim engines on five underground loaders and one underground truck in a move to lower emissions and increase fuel efficiency.

The Tier 4i engines will be available as an option on the underground loaders Scooptram ST7, ST7LP, ST1030, ST1030LP and ST14, as well as on the underground truck Minetruck MT2010.

“With the new engines you get lower emissions along with higher fuel efficiency,” confirms

Ben Thompson, Product Manager at Atlas Copco. “It means you will reduce the fuel consumption, but also that you can cut down on the required ventilation resulting in great savings to operating costs. In addition, you get a healthier working environment for all personnel in the mine.”

The Tier 4i engines feature improved performance and torque response via variable geometry turbocharging and an enhanced fuel system. This can provide up to 5% greater efficiency than the equivalent
Tier 3 engine.

The passive regeneration of the diesel particulate filter is automatic while still maintaining high machine performance. In addition, no diesel exhaust fluid is required which also contributes to lower costs and fewer production stops.

Epiroc operated under the trademark “Atlas Copco” prior to January 1, 2018.
