PowerTech™ 6081 Industrial Engines
The Tier 2 PowerTech 8.1L engines from John Deere offer a new level of power, fuel economy, improved oil consumption, air-to-air cooling and an electronically controlled fuel system.
This innovative technology will be incorporated into each 8.1L Tier 2 engine. With the HPCR, the fuel pump is sending constant pressure into a common rail, supplying each injector with constant pressurized fuel that is available when the electronic injector opens. Also, the new injectors are vertical and centered.
