Proven Economy, Proven Durability
The challenge of real-world durability proven in service. Millions of in-service miles have earned the International T 444E the reputation of a durable performer. To verify this, T 444E engineers performed teardown inspections of fleet-owned,daily-operated engines with 300,000 to nearly 500,000 miles of accumulated service. Meticulous inspection of the engines showed minimal signs of wear, and no major repairs had been required during the life of the engines.
How is it possible to achieve such impressive service? The T 444E is smart. Its integrated design is reinforced with strong components to ensure reliable, everyday workhorse performance and long life.Features
Single 8-Groove Poly-Vee Serpentine Belt Drive is self-tensioning, resulting in a virtually maintenance-free design.
Gear-Driven Front-End Drive Components: Power Steering Pump for trouble-free operation and greater reliability and durability.
Gear-Driven Front-End Drive Components: High-Pressure Oil Pump for trouble-free operation and greater reliability and durability.
Gear-Driven Front-End Drive Components: Camshaft for trouble-free operation and greater reliability and durability.
Hydraulic Tappets With Roller Followers eliminate the need for valve lash adjustments.
Plateau-Honed Cylinder Bores contribute to long bore life and superior oil control and uniform piston ring lubrication.
Forged Micro-Alloy Steel Crankshaft fillets and journals are induction-hardened for strength and durability. Large bearing surfaces ensure long engine life and advanced manufacturing processes assure precision and uniformity.
Forged Steel Connecting Rods with large bearing surfaces provide exceptional strength and long life.
Piston Cooling Jets provide optimum temperature control and lubrication, resulting in longer life.
Keystone Plasma Faced Top Ring minimizes oil consumption and emissions while increasing power cylinder life.
Electronic Glow Plugs standard on the T 444E, provide unaided cold starts down to -20°F.
Electro-hydraulic fuel sytem with Split-Shot™ provide optimum performance, maximized fuel economy and precise fuel delivery. Clean burning T 444E engines have been used to demonstrate 2004 emissions capability years ahead of schedule.
Optimized Turbocharger provides powerful, economical and quieter operation. An integrated oil supply and drain for the turbocharger eliminate external tubes and connections for greater reliability.
Air-to-Air Intercooling on all ratings provides maximum efficiency, fast response and consistent performance at virtually any altitude.
Powerful Diamond Logic© Electronics control, monitor and record hundreds of operational parameters for maximized performance, quieter operation and reduced emissions.
