Lower emissions, increased profit for mines

As well as being cleaner, the Tier 4 engine generation for mine vehicles uses far less fuel than older engines.
Several mine operators seized the chance to test the new MTU engines before the official sales kick-off. Four years ago, for example, MTU replaced the 16V Series 4000 Tier 1 engine in a Komatsu 930 haul truck with a modern Tier 4 engine in the same series. The mine operator ran the tests to find out more about the latest Tier 4 engine technology before the new emissions regulations kicked in. The aim was to accurately gage how the new units would influence mine operation and maintenance processes. The MTU engineers involved used the opportunity to get a more accurate picture of the performance capabilities of their Tier 4 technology in a tough mining environment. Instead of using a 16-cylinder engine, they fitted a 12-cylinder Series 4000 unit – and the move proved successful. The Type 12V 4000 Tier 4 engine delivered 1,864 kW (2,500 PS) of power and reached the same speed on slopes as its 16-cylinder Tier 1 predecessor – whilst using significantly less fuel. “We couldn’t have given the customer better proof that our Tier 4 engines deliver outstanding value,” concluded Archer
