Doosan loader hits mark for US and EU emissions standards


Korean construction equipment giant Doosan Infracore has launched a Tier 4i-compliant wheel loader.

The DL300-3, which has a bucket capacity of 3m3, is the smallest model in the firm’s new family of Tier 4i-compliant large wheel loaders. It is designed for a wide range of material handling activities, including loading and transporting granular material.

The machine is powered by a 9l Scania diesel engine that complies with the latest European and United States emissions legislation through the use of selective catalytic reduction (SCR) and diesel particulate filter after- treatment technologies.

Doosan claims the SCR technology reduces fuel consumption by about 10% compared to similar size machines with exhaust gas recirculation technology.

It says reselling the machines is also easier because it is simple to reset the engines to lower Tier 2 requirements for resale in emerging markets that do not have such tight emissions regulations. Fuel consumption is further reduced by the incorporation of three engine working modes, Eco, Normal and Power, each designed for different applications.

For example, the operator can travel in moderate Normal mode and only switch to Power mode when it is needed, such as when taking material from a pile.

Another fuel saving device is auto idle, which automatically reduces engine speed to 200rpm after 10 seconds if there is no machine movement. Doosan estimates that this function will reduce overall fuel consumption by up to 8%.
