WARRENVILLE, Ill. — For the first time, International Truck and Engine Corporation has combined all of its industry leading diesel engine technologies into one design.

The new in-line six-cylinder (I-6) family of International engines for 2004 International 4000 and 7000 series and 8500 trucks provide business owners with higher performing engines that set higher standards.

Drivers of International trucks powered by the new engines will benefit from a technology platform established with the International VT 365 engine. This matured platform provides truck owners with new levels of reliability, durable performance, driver responsiveness and easier serviceability that set new standards for commercial trucks. The new International I-6 engines will provide a valuable ownership experience over the lifecycle of the vehicle.

“Our challenge was to deliver to our customers more value, while meeting stringent 2004 emission requirements with technologies weve been maturing such as cooled EGR and the variable response turbochargers,” said Patrick Charbonneau, vice president and chief technology officer, International Engine Group. “The result is a family of engines that will provide improved fuel economy and SUV like performance. We were able to accomplish this because of Internationals integrated truck and engine design and production capabilities.”

As the trucking industry continues to grow, the demand for automotive-like drivability and performance, including more responsive acceleration and peak power is also increasing. The new family of International I-6 engines provide drivers with the power of a work truck, as well as the performance and responsiveness one expects to find in a SUV.

Meeting the 2004 EPA emission standards was just one goal of the new International I-6 engines. International has taken durability and reliability to the next level, beyond the proven replaceable induction hardened wet sleeve engineering, positive valve rotators and replaceable valve seats and guides, roller cam followers, targeted piston cooling jet designs and thirty-six bolt cylinder / head clamping design that have made International an industry leader. The new International DT 466, DT 570 and HT 570 incorporate a number of innovations, which redefine durability and reliability.

As important as performance, International engineers recognized that ease of serviceability would have to be included on the International I-6 family of engines. With an integrated fuel filter that improves filter life, reduces the cost of service and nearly eliminates break downs caused by improper servicing of auxiliary filters and leaks.

Hitting the road this spring and summer, the new 2004 International DT 466, DT 570 and HT 570 engines for International 4000 and 7000 series and 8500 trucks take the rich tradition of outstanding vehicle, employee and financial performance even further.
