What type of engine is equipped in a Cessna 172?

The Cessna 172 is typically equipped with a Lycoming 4-cylinder normally aspirated engine, which is known for its reliability and simplicity. This type of engine operates by drawing air and fuel into the cylinders via atmospheric pressure without the use of a turbocharger, making it well-suited for general aviation and training purposes.

The design of the Lycoming engine facilitates easier maintenance and operation at the altitudes typically flown by small general aviation aircraft like the Cessna 172. The engine generates sufficient power for the aircraft's performance requirements while remaining efficient for its size and commonly used altitude range.

In contrast, turbocharged engines, rotary engines, and V8 engines are not standard for the Cessna 172. Turbocharged engines can provide higher performance at higher altitudes but are more complex and are not found in the standard 172 models. Rotary engines, known for their unique design and power capabilities, are not utilized in traditional fixed-wing aircraft like the Cessna 172. V8 engines, generally associated with larger vehicles or high-performance applications, do not fit the design or performance needs of a single-engine general aviation aircraft like the 172.
