Tier 2 PowerTech Industrial Engines - 6125
The PowerTech 12.5L series was developed with Tier 2/Stage II requirements in mind. Externally, the only change is a new center air intake manifold. Our 12.5L engines employ electronic unit injectors for higher injection pressures, and a turbocharger for better air flow. Both features improve engine performance and help meet emissions regulations.
The electronic control unit in the 12.5L engines includes a 10 percent bulge below rated speed, fuel temperature compensation, onboard diagnostics, and expanded engine protection.
Heat rejection and fuel consumption ratings on the Tier 2/Stage II 12.5L engines are equal to or better than their Tier 1/Stage I counterparts.
