BMW 320i Engine Parts

The turbocharged four-cylinder engine in your BMW 320i is made up of many parts, all of which work together to produce the power your compact executive car needs to move on down the road.

The core of it all is the engine block. Other parts connect to it, and it's home to the combustion that creates the power that moves your wheels. Engine pistons pump in order to pressurize the air-and-fuel mixture inside the engine block, while a cylinder head seals the gases inside. The spark-plugs that kindle ignition connect to that cylinder head. The camshaft syncs with the crankshaft to open and close the valves as needed, with the crankshaft using the pistons' pumping motion to produce the rotary motion that moves your drivetrain. An oil pan holds the motor oil that lubricates your engine, while rings, gears, gaskets, and bearings keep everything connected.

How to Spot Faulty Engine Parts

Harsh driving conditions and time can take a toll on even the best engine parts, though. Signs of failure include:

  • Repeated engine stalls
  • Problems accelerating
  • Rough engine idling
  • Worsening fuel efficiency
  • Excessive exhaust smoke
  • The "Check Engine" dash light comes on
