Tighter communications help OEMs meet tighter regulations

Closer links between powertrains and hydraulic systems cut fuel usage and emissions while improving efficiency.

As regulations including Tier 4 further restrict fuel consumption requirements, design teams are tightening the links between powertrains and hydraulic systems. Improving communications between the two can bring significant savings while also reducing size and weight.

Advanced electronics permit matching the hydraulics demand and the engine load, which cuts fuel usage while improving hydraulic performance. Engines can run in their sweet spots longer and hydraulic systems can deliver power more quickly when they don't have to wait for engines to rev up. These revisions also help trim emissions.
