Which Consumes More Fuel: Naturally Aspirated or Turbocharged?

[RuthDella]

Under the same engine displacement and working conditions, naturally aspirated engines consume more fuel. Below is an introduction to naturally aspirated and turbocharged engines: 1. Naturally aspirated engines do not have a supercharger. Air simply passes through the air filter—throttle (commonly known as the "accelerator")—intake manifold—and reaches the "cylinder." Gasoline is directly injected into the intake manifold via the fuel injector. 2. Naturally aspirated engines rely on the naturally formed pressure difference to draw in the air-fuel mixture during the first stroke. Turbocharged engines, on the other hand, compress the air first to increase its pressure and density. When the valve opens, the pressure difference and the high pressure of the gas itself increase the intake volume, thereby boosting power.
