Zorluk: OrtaFuel and Air Intake Systems

In a turbocharged gasoline engine, intake air travels through several induction components before entering the combustion chamber. What is the correct order of components that the air passes through from the outside atmosphere to the engine cylinder?

  1. 1Air cleaner assembly
  2. 2Turbocharger compressor
  3. 3Charge air cooler (intercooler)
  4. 4Throttle body assembly
  5. 5Cylinder intake valve

Cevap

Air cleaner assembly → Turbocharger compressor → Charge air cooler (intercooler) → Throttle body assembly → Cylinder intake valve
In a turbocharged gasoline engine, ambient air is first drawn through the air cleaner assembly to filter out airborne contaminants. It then enters the turbocharger compressor housing where the impeller wheel pressurizes it. Because compression generates substantial heat, the hot air is directed through a charge air cooler (intercooler) to reduce temperature and increase charge density. The cooled air then passes through the throttle body assembly, which regulates intake air volume, before traveling through the intake manifold runners and past the cylinder intake valve into the combustion chamber.

Adım Adım Çözüm

1
Identify the initial atmospheric entry point for induction air.
Air enters the air cleaner assembly.
Air must be filtered immediately upon entering the vehicle to prevent particulate damage to sensitive downstream induction components.
2
Trace the forced induction compression stage.
Filtered air enters the compressor housing of the turbocharger.
The exhaust-driven turbine spins the compressor wheel, drawing in clean air and compressing it above atmospheric pressure.
3
Account for charge air cooling.
Pressurized air routes through the charge air cooler (intercooler).
Air heats up during compression; passing through an intercooler removes heat, increasing air density and preventing engine knock.
4
Determine airflow regulation into the manifold.
Cooled charge air moves through the throttle body assembly.
The throttle valve controls engine speed and load by regulating the volume of boost air entering the intake manifold plenum.
5
Identify the final entry point into the combustion chamber.
Air passes the cylinder intake valve.
The mechanical intake valve opens during the piston's intake stroke to admit the fuel-air charge into the combustion chamber.
