2000 Cummins N14

The 2000 Cummins N14 diesel engine is a renowned diesel engine often seen in commercial trucks, recreational vehicles, and agricultural and construction vehicles. The N14, which was based on a basic 855 cubic inch Cummins engine, was manufactured from the late 1980s until 2000 when it was phased out and replaced by the ISX engine. The N14 got a few minor upgrades throughout its manufacturing years, but its fundamental design remained the same at its core.

Performance and Fuel Economy

In terms of durability, this engine is setting the bar high based on the performance of nearly 150,000 N14 engines currently on the road. The combination of a great reputation for extended life-to-overhaul and the flexibility to easily upgrade to higher horsepower results in the highest possible resale value. CELECT Plus is equipped with an upgraded electronic control module that delivers additional customer features, better engine controls, and cruise control in the manner of a conventional automobile. 2000 Cummins N14 Plus engines include more modern electronic engine controls and hardware enhancements, which allow them to get greater mileage.

Increased starting torque results in greater “lift” when the clutch is released at a faster rate, and increased power results in increased high-speed performance, even when the system is severely loaded. When driving up a steep incline, drivers may make use of the ESP Plus feature, which is available as an option. Significantly reduces the amount of shifting. Stepping on the throttle at any speed causes the N14 Plus to respond very instantly.

Power, Proven Solution, and Support Network

When picking gearing combinations, it is critical to take into consideration the actual ratio and tire rev/mile statistics. If you are looking for information on accessible transmission top-gear and drive axle ratios, a competent truck salesman or Cummins distributor can provide you with that information and the number of actual tire revolutions per mile for a specific tire that is going to be used on the drive axle.

It is occasionally suggested to use lower numeric (faster) axle ratios to achieve greater maximum vehicle speeds while maintaining lower engine rpm at the vehicle’s regular cruising speed. Consider the following factors when evaluating these combinations: (a) the rise in highest vehicle speed will be minor; (b) the fuel efficiency benefit linked to lower cruise rpms is difficult to quantify; and (c) most importantly, the vehicle’s grade-climbing functionality will be adversely affected, leading to increased gear shifts; It is recommended that you engage with an authorized Cummins representative and request a Vehicle Mission SimulationTM to fully comprehend the relative differences among different gearing combinations. The performance of heavy-haul trucks is determined by the application in which they are used.

When choosing gearing for a 2000 Cummins N14 Plus engine capable of carrying more than 80,000 lb GCW, it is recommended that you confer with a Cummins authorized agent. The gearing suggestions made for a Cummins N14 Plus engine capable of pulling up to 80,000 lb GCW: For the best possible fuel efficiency (mpg): A gearing combination (transmission ratio, tire revs/mile, drive axle ratio) that results in roughly 1450 rpm while traveling 65 miles per hour is chosen as the best option. For automobiles traveling at or above 65 miles per hour, a gearing combination (transmission ratio, tire revs/mile, drive axle ratio) that results in roughly 1450 rpm while traveling 65 miles per hour is chosen as the best option. Vehicles that will travel less than 65 miles per hour and for which maximum fuel efficiency is not required: A gearing combination (transmission ratio, tire revs/mile, drive axle ratio) that results in roughly 1550 rpm while traveling 65 miles per hour is chosen as the best option.
