What are the different types of engine intake methods?
1 Answers
Common engine intake methods are divided into three types: naturally aspirated, turbocharged, and supercharged. Naturally Aspirated: Naturally aspirated refers to an intake method where the car engine relies on the vacuum negative pressure generated by the downward movement of the piston, allowing atmospheric pressure to directly push air into the engine combustion chamber without any supercharger. Naturally aspirated engines excel in smooth power output and direct responsiveness, far surpassing supercharged engines. They offer advantages such as a wide usable RPM range, simple structure, low cost, and easy maintenance. Turbocharged: Turbocharging is an intake method that uses exhaust gases generated by the internal combustion engine to drive an air compressor. Under the same displacement, it can significantly increase engine power and torque by approximately 40%. However, the advantages and disadvantages are also evident. Turbocharging maintenance costs are considerably higher, and in most urban driving conditions, the turbocharger does not operate. Supercharged: Supercharging is an intake method where a mechanical air compressor is connected to the crankshaft, using the engine's crankshaft power to rotate the air compressor and compress air. Since the supercharger is always boosting, it delivers excellent torque output even at low engine RPMs.
