In the engine is naturally aspirated without the use of a turbocharger, the air pressure is controlled by the downward movement of the piston is generated, so that the atmospheric air directly into the engine combustion chamber. At present, most domestic car engines have adopted this intake form.
1. Disadvantages naturally aspirated
· advantages smooth output power, fast response, high speed range is available. Oil and water temperature can be controlled in a range more suitable for the operation of the engine, longer engine life. Simple structure, low cost, easy to maintain.
· drawbacks of the same displacement is weaker than the naturally aspirated engine equipped with a turbocharger engine power.
2. How to distinguish naturally aspirated
no turbocharger is a naturally aspirated engine, a supercharger is larger thing, one can see it.
