What is? Air pressure
is a naturally aspirated engine without the use of a turbocharger, rely on 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.
· smooth output power, fast response large speed range available.
and the oil-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.
– the same displacement than the naturally aspirated engine equipped with a turbocharger engine power is weak.
How to distinguish?
no turbocharger is a naturally aspirated engine, a supercharger is larger thing, one can see it.
