Why are Ferrari series engines naturally aspirated instead of supercharged?

Naturally aspirated engine technology is stable and mature, its output power is stable, its reaction speed is faster, its power is worse than that of turbocharging, but its later maintenance cost is not as high as that of turbocharging. Naturally aspirated engines are more durable than turbocharged engines. Many compact turbocharged models need to add 95 # gasoline to maintain the car, and naturally aspirated engines can add 92 #.

Naturally aspirated engines are far superior to supercharged engines in terms of smoothness of power output and directness of response, and the current V8 2.4L F 1 engine is the best example.

Workflow of naturally aspirated engine

Naturally aspirated without supercharger. Air simply passes through the air filter, throttle, that is, throttle, enters the intake manifold, reaches the "cylinder", and then gasoline is directly injected into the intake manifold through the fuel injector. Taking a four-cylinder engine as an example, an engine piston has four strokes at a time: intake-compression ignition-push work-exhaust.

Specifically, in the first stroke, the piston descends, the intake valve opens, and the mixture of air and fuel enters the cylinder under the action of pressure difference; In the second stroke, the intake valve is closed, the piston goes up to compress the mixture, and when it reaches the highest point, it is ignited; The third stroke, after ignition, pushes the piston to do work and output power;

On the fourth stroke, the piston rises again. At this time, the exhaust valve is opened to discharge the exhaust gas. Inhale naturally in the first stroke, and inhale by natural pressure difference. This repetition is the workflow of naturally aspirated engine.
