Is a 2.5L Naturally Aspirated Engine Considered a Large Displacement?

[EdwardLynn]

2.5L naturally aspirated models belong to the large displacement category. Below are detailed explanations about automotive engine displacement: 1. Concept: Displacement is an important indicator for evaluating engine performance. The volume of fluid inhaled or exhausted by the engine per stroke or cycle is called the engine's intake volume. The working volume swept by the piston moving from top dead center to bottom dead center is called the cylinder displacement. If an engine has multiple cylinders, the sum of all cylinders' working volumes is referred to as the engine displacement. It is generally expressed in liters (L) or cubic centimeters (cc). 2. Horsepower: Horsepower is defined as the power exerted by a horse capable of pulling 33,000 pounds at a speed of one foot per minute, with watts (W) or kilowatts (kW) used as standard units. That is, 1 metric horsepower = 75 kilogram-force·meters/second = 735 watts. For a 1.6L displacement engine, depending on the brand and tuning methods, if it's a naturally aspirated engine, the horsepower typically ranges between 100 to 120. With turbocharging technology, it can reach up to around 130 horsepower.
