International Diesel Engines. Light Duty Trucks and Heavy Duty Trucks.

International has been in the automotive business for over one hundred and ten years. The company that manufactures International engines is not the same company that produced farm equipment, trucks, buses, and gas turbines back in the agricultural boom of the early 20th century because of division sell-offs and a changing economy, but it’s a powerhouse in the world of truck engines today.

The company changed its name to Navistar in 1986, and the mission was to develop a series of large replacement V8 diesel engines that were reliable and could perform under the hood of ¾ ton and 1 ton trucks.

When Navistar partnered with refurbished Ford in the 1980s the mid-size truck market changed forever. These new International diesel engines were powerful, durable, and had torque capabilities that set a new standard in diesel engine technology. The first diesel engine was the 6.9 liter, 170 horsepower, with 315 ft-lbs of torque, indirect injection engine (IDI), which was aptly named the first Powerstroke engine.

The 7.3 liter IDI diesel engine followed in 1988. It carved a new niche in truck power and durability until 1993. That’s when the Turbocharged 7.3 liter diesel was introduced. The 7.3 liter turbocharged, direct injection (DI) engine revolutionize the diesel truck market, and became an instant hit. The 7.3 liter diesel had HUEI fuel injectors and an air-air intercooler. Over two million 7.3 liter truck engines are still in operation even though production stopped in 2003.

A new Powerstroke engine was introduced in 2003 that could meet emission standards, and still provide the awesome power that consumers wanted under the hood of their trucks. This 6.0 liter Powerstroke had 320 horsepower with 518 ft-lbs of torque, but the engine displacement was drastically reduced to conform to new emission requirements.

In 2007, the 6.4 liter Powerstroke diesel engine was introduced with 350 horsepower and a peak torque output of 650 ft-lbs at 2000 rpms. That engine provided the quietest and cleanest ride of any Powerstroke engine to date thanks to twin turbochargers, and common-rail fuel injection with piezoelectric fuel injectors. The lighter and more powerful 6.7 liter Powerstroke diesel was introduced in 2011 with glow plugs, instant start, and a new lightweight graphite engine block with aluminum cylinder heads.
