N14 Cummins Quick Sheet
The N14 Cummins was definetly one of Cummins most popular engines. Used to power everything from over the road trucks to motorhomes to mining equipment to generators, the Cummins N14 was very versatile.
The Cummins N14 was built on the basic design of the 855 cubic inch Cummins engine. In the early 1990's, Cummins redesigned the engine with electronic controls to meet EPA regulations. The redesigned engine, known as the Celect fuel system, featured an Electronic Control Module (ECM) and electronic injectors. Although injectors were still cam activated, the Cummins ECM controlled fuel at the electronic injectors. In 1997, Cummins released the upgraded N14 with the Celect Plus fuel system. Although not noticably different looking, the Celect Plus ECM has many more adjustable parameters for customer fine tuning. The Cummins N14 was discontinued around 2000, and has been replaced by the
Cummins ISX.
