The Cummins N14 is a popular diesel engine that is primarily installed in commercial trucks, recreational vehicles, and agricultural and construction equipment. Built on a base 855-cubic-inch Cummins engine, the N14 was produced from the late 1980s through 2000, when it was discontinued and replaced by the ISX line of engines. The N14 received a few minor updates throughout its years of production, but it stayed the same at its core.
