Naturally aspirated engine Naturally aspirated engine A naturally aspirated engine is an internal combustion engine in which oxygen intake depends solely on atmospheric pressure and does not rely on forced induction through a turbocharger or a supercharger. Many sports cars specifically use naturally aspirated engines to avoid turbo lag. In a naturally aspirated engine, air for combustion (diesel cycle in a diesel engine or specific types of Otto cycle in petrol engines—namely petrol direct injection), or an air/fuel mixture (traditional Otto cycle petrol engines)—is drawn into the engine’s cylinders by atmospheric pressure acting against a partial vacuum that occurs as the piston travels
