Here are a few contenders, with different interpretations of "largest":
By Displacement:
* Wärtsilä-Sulzer RTA96-C: This is technically a marine engine, but it's often listed as the largest engine ever built. It has a displacement of 25,480 liters (1,555 cubic inches) and is used in container ships.
* Caterpillar 3600 Series: These are large diesel engines used in mining and power generation. They can reach displacements of over 1,500 liters (91 cubic inches). While not as large as the Wärtsilä-Sulzer, these are still incredibly powerful and are sometimes used in custom-built vehicles.
By Number of Cylinders:
* The "Big Block" Cadillac 472 & 500: While not the largest by displacement, these engines are renowned for having 8 cylinders in a massive "big block" configuration. They were legendary for their power and torque.
By Power Output:
* The Koenigsegg Jesko: This hypercar boasts a 5.0 liter V8 engine that produces a mind-boggling 1,600 horsepower. While smaller in displacement, it generates incredible power.
In Conclusion:
Defining the "largest" engine is subjective. It depends on your criteria: displacement, number of cylinders, power output, or even weight. All of these contenders are incredibly powerful and impressive feats of engineering.
