Diesel Engines : International® Engines : DT 466
International® Engines - DT 466
The International DT 466 is the long-standing gold standard for medium-duty trucks. Totally rebuildable in chassis with wet-sleeve architecture, there's simply no better engine to own, operate and maintain. The International DT 466, along with the rest of the International® engine family, is a big reason why International® 4000 Series trucks retain such a high resale value.
Features
Improved Performance.
|
|
|
 |
The International® EVRT® electronically controlled turbocharger features adjustable vanes that optimize boost across the entire operating range - providing more responsive acceleration and peak power ,and reducing turbo lag. | |
|
The International® Electro-Hydraulic Generation Two (G2) fuel system is a common-rail design, with no high-pressure external lines driving digital valve injectors. The G2 system offers more precise timing control for optimized fuel delivery, meaning better fuel efficiency and reduced emissions. The system is also commercial jet "A", JP-8 and bio-diesel (B-20) capable. | |
|
With the Intuitive ShiftT automatic transmission interface, transmission shift points are matched with engine power curves for smoother operation and increased performance, reliability and fuel economy. |
More reliable. More durable. More uptime.
|
|
|
|
Longer engine life is achieved with durability-enhancing features like six bolts per cylinder on the cylinder head, roller cam followers that utilize roller bearings and pad-mounted accessories | |
|
Positive valve rotators ensure longer valve and valve seat life. | |
|
Each piston's targeted cooling jet delivers 30% better piston cooling with a simplified design for longer piston life. | |
|
Targeted cooling jet delivers better piston cooling with a simplified design for longer piston life. | |
|
Integration with the International® Diamond LogicT electrical system brings advanced diagnostics for quicker troubleshooting, faster repairs and increased uptime. | |
|
Uptime is increased with a top-loaded fuel filter that provides easy access for quick filter changes. | |
|
An optional electronically- controlled integrated intake air heater for faster starts in cold weather. | |
|
An optional powder-coated oil pan protects against harsh road salt and environmental conditions. The oil pan features dual drain plugs that allow dealer installation of an oil pan heater. | |
|
The advanced oil filtration system features a high-valve centrifuge oil fileter that comes standard on International® I-6 diesel engines at no additional cost. This premium filter increases the total filter capacity of the engine; extends engine, oil and filter life; improves fuel efficiency and achieves greater filter efficiency than a full-flow filter alone. |
Better breathing. Higher efficency.
|
|
|
|
Four valves per cylinder and central injectors allow for more efficient combustion. | |
|
Intake ports maximize airflow and swirl patterns into the combustion chamber for efficiency, performance and low emissions. | |
|
Redesigned intake manifold ensures more efficient airflow. | |
|
Cooled Exhaust Gas Recirculation (EGR) reduces oxides of nitrogen (NOx) to comply with clean air standards, today and tomorrow. |
Designed for minimal leaks.
|
|
|
|
Potential leak paths have been reduced through integrated system design. | |
|
Pipe thread ports and fittings have been replaced with SAE O-ring boss ports and fittings. | |
|
The variable displacement high-pressure oil pump provides enhanced fuel injection capability with improved efficiency. | |
|
The rear crank seal is integrated into the flywheel housing, reducing leak potential and increasing durability. | |
|
A one-piece stacked-plate oil cooler provides improved capability and features a virtually leak-free design. | |
|
Paper gaskets have been eliminated and replaced with premium no-compromise gasket polymers that are tailored to seal oil or water. Valve cover and oil pan gaskets are reusable. | |
|
The high-pressure oil rail features a one-piece design that is located under the valve cover to minimize external plumbing and leaks. |
Unmatched braking performance.
|
|
|
|
The optional International® Diamond LogicT exhaust brake is integrated into the EVRT turbochargerwithout external braking devices. The exhaust brake provides up to 150 bhp. | |
|
The optional Diamond LogicT engine brake provides the braking power of traditional mechanical engine brakes with significantly reduced noise levels. The engine brake provides up to 275 bhp. | |
|
Redesigned intake manifold ensures more efficient airflow. | |
|
Both brake systems integrate with cruise control to help keep the vehicle at desired speeds. |
