1. Design and Functionality of the 4 Cylinder Engine

The 4 cylinder engine is commonly found in compact cars, sedans, and even some SUVs. Its design boasts four cylinders arranged either in-line or horizontally. Here are the main components that define its functionality:

1. Cylinders: Each cylinder houses a piston that compresses fuel and air for combustion.
2. Combustion Process: The engine operates on the principles of the four-stroke cycle: intake, compression, power, and exhaust.
3. Balance: With fewer moving parts than bigger engines (like V6 or V8), the 4 cylinder engine has reduced vibration and smoother operation.

2. Power Output

While a 4 cylinder engine may not deliver the horsepower of larger engines, it still packs a punch. Here’s how it satisfies power needs:
