Most people have little or no idea what an International 6.9L engines is, until I mention that was the venerable diesel engine first used in Ford F-Series Pickup trucks. Developed In March of 1978, by a combined effort of the International Harvester Corporation and Ford Motor Company, a suitable diesel engine that would eventually change the way pickup trucks and light-duty vehicles would be powered.
The new motor consumed 420cid or 6.9L [US/metric], it is naturally aspirated, [which has no turbocharger], indirect-injected (IDI), diesel motor. With eight cylinders it would become the first light duty US diesel built truck powered by a diesel engine. It started a nice competition between the big three automakers, currently still competing.
The Ford/IHC 6.9L engine featured a bore of 4.00 inches, a stroke of 4.18 inches, produced 170 hp and 310 lb-ft of torque with a 20.7:1 compression ratio. For a relatively large engine the ratings were low, but 24 years ago it started a diesel revolution that has intensified over the years, introducing turbochargers and more technology to outdo the other manufacturers.
Seriously though, it was a great idea and for construction industry people, these diesel powered one ton trucks really served a purpose. Allowing a more durable engine with better fuel economy and less maintenance.
The Engine block is made from cast iron, the 6.9L featured 4-bolt iron main bearing caps. This was done for reliability and also to increase the stiffness of the lower end of the block. The whole design of the block has to very structurally rigid allowing for the increased compression diesel engines use to com-bust the diesel fuel.
Ford certainly chose a worthy partner to develop an engine with. The 6.9 started a revolution and continued with the legendary 7.3L Power Stroke diesel engine which was also a combined effort.
