What is the engine specs of the Cessna 172?
The Cessna 172S was introduced in 1998 and is powered by a Lycoming IO-360-L2A producing 180 horsepower (134 kW). The maximum engine rpm was increased from 2,400 rpm to 2,700 rpm resulting in a 20 hp (15 kW) increase over the R model. As a result, the maximum takeoff weight was increased to 2,550 lb (1,157 kg). The Cessna 182 is a larger, more powerful version of the 172. It features a 230-horsepower engine compared to the 172’s 160–180 HP. The 182 offers faster cruise speeds, greater payload capacity, and more advanced systems, making it better for cross-country or high-performance training.
What is the difference between fuel injected and carbureted Cessna 172?
The main difference between carbureted and fuel-injected Cessna 172 engines is how they deliver fuel to the engine. Carbureted engines mix fuel and air in a simple way but can suffer from carburetor icing, while fuel-injected engines send fuel directly into the engine and run more smoothly. Engines equipped with fuel injection provide higher power and torque than a carbureted version of the same engine. The accuracy of fuel injection and modern electronic controls lead to fuel delivery that matches driver demand.In summary, fuel injection systems generally provide greater power delivery and better fuel economy, while carburetor engines are more affordable and easier to repair.Since fuel injection systems shoot fuel directly into the cylinders, they are easier to flood (too much fuel) when starting. Though easier to start, carbureted engines are less efficient during flight. Since the fuel/air mixture in these systems meet at the carburetor, the mixture is less precise for each cylinder.
Do Cessna 172S have carb systems?
David Russell Jacobson most 172s use carburetors; newer models use a mechanical port injection system. Modern Cessna 172S models utilize fuel injection systems with an engine driven fuel pump and electric auxiliary pump, while earlier carbureted versions like the 172N rely primarily on gravity feed with minimal pump assistance.
