Tier 2 PowerTech Industrial Engines - 6081
Tier 2/Stage II PowerTech 8.1L engines offer exceptional levels of power and fuel economy, and feature the high-pressure common rail (HPCR) fuel system that provides higher injection pressures, variable timing control, and more precise control of fuel injection.
In the HPCR system, fuel is pumped into a common rail at a constant pressure, and is available when each electronic injector opens. The injectors in this system are vertical and centered over the pistons for improved fuel combustion.
Fuel delivery in the HPCR system is controlled by an electronic control unit that maximizes fuel efficiency by regulating fuel delivery for various loads and speeds.
