Filtration Solutions forToday's Diesel Engines Diesel engine technology continues to evolve quickly in response to increasingly stringent emissions standards.Today’s engines now operate at much higher temperatures and under much greater pressures. Because tolerances have become tighter, contamination control for fuel, lube, and coolant systems is critical. Donaldson understands the filtration challenges faced by modern engines and offers a broad array of solutions to meet even the most demanding requirements.
Fuel Filtration see page 7 Systems to AddressToday's Fuel Challenges
High-pressure fuel injection systems require more efficient fuel filtration with longer life. Donaldson fuel filter assemblies provide you with the flexibility to select the proper filtration system to meet your fuel quality requirements.
