  • The N-14 diesel engine for Cummins Inc., features a revolutionary oil-cooling technique, which extends the engine's operating period and allows a reduction in engine weight, resulting in enhanced savings for the manufacturer. The N-14 engine, with models ranging from 300 to 450 horsepower, achieves major improvements in fuel economy, noise reduction, durability, and emissions while retaining enough commonality with current N-type engines to permit use of much of Cummins existing tooling and transfer lines. The arrangements of the Turbo charger, after-cooler, and crossover on one side of the engine has resulted in a height reduction of nine inches allowing it to fit a greater range of vehicles. The cylinder block and valve covers express power and denote structural strength. The dark blue and black color scheme emphasizes ruggedness.
