A 114 cubic inch (cu in) engine is equivalent to 1868 cc. This measurement typically refers to the displacement of an internal combustion engine, indicating the total volume swept by all the pistons in one complete revolution.
Understanding Engine Displacement: Cubic Inches vs. Cubic Centimeters
Engine displacement is a fundamental specification that describes the size of an engine. It's measured in either cubic inches (cu in) or cubic centimeters (cc), with both units representing a volume. Larger displacement generally correlates with greater power and torque, though other factors like engine design and technology also play a significant role.
The "114" in question specifically points to the displacement in cubic inches, a common measurement, especially for American-made engines like those found in Harley-Davidson motorcycles.
The Milwaukee-Eight® 114 Engine Example
A prime example is the Milwaukee-Eight® 114 engine, which boasts a displacement of 114 cubic inches. According to specifications, this translates precisely to 1868 cc. This powerful engine is featured in various models, including the Harley-Davidson Ultra Limited, Road Glide® Special, Street Glide® Special, and Road King® Special.
Engine Displacement Conversion
| Unit of Measurement | Value |
|---|---|
| Cubic Inches (cu in) | 114 |
| Cubic Centimeters (cc) | 1868 |
This conversion highlights the relationship between two common units of engine volume:
- Cubic Inches (cu in): Often used in the United States, particularly for V-twin and V8 engines.
- Cubic Centimeters (cc): A metric unit widely used globally, especially for motorcycles and smaller car engines.
Why Engine Displacement Matters
Engine displacement directly impacts a vehicle's performance characteristics. Here's why it's a key specification:
- Power and Torque: Generally, a larger displacement engine can burn more air and fuel per cycle, leading to greater power output and higher torque. This results in quicker acceleration and better pulling capability.
- Fuel Efficiency: While larger engines often provide more power, they typically consume more fuel. However, modern engine technologies like variable valve timing and cylinder deactivation can improve the fuel efficiency of larger displacement engines.
- Engine Character: The displacement contributes significantly to an engine's "feel" – whether it's rev-happy and high-strung (often smaller displacement) or torquey and relaxed (often larger displacement).
