Automotive Information -Internal Combustion System Components Flashcards
Forms the framework for the engine cylinders and reciprocating assembly.
Engine Block
A cylindrically shaped object with a solid crown that moves up and down in the engine’s cylinders. Hot gases produced from the combustion of the air-fuel mixture push on this component to do the actual work.
Piston
Forms a guide for the piston to move in; allows the piston to move up and down as the engine completes its cycle.
Cylinder
Seal the piston to the cylinder and prevent combustion gases from leaking past.
Piston Rings
Connects the piston to the connecting rod, and forms a pivot point for the small end of the connecting rod to move on.
Wrist Pin
Connects the piston/ wrist pin assembly to the engine’s crankshaft. the large end connecting the road attracts to the crankshaft on the connecting rod journal.
Connecting Rod
Converts the linear motion of the piston into rotary motion, which can the be used to power a vehicle or drive an accessory.
Crankshaft
Located above the piston, it houses the combustion chamber, intake and exhaust valves, and the intake and exhaust ports.
Cylinder Head
Located in the cylinder head directly above the piston, it is where the actual combustion of the air-fuel mixture takes place.
Combustion Chamber
Allows the air-fuel mixture to be drawn into the combustion chamber. When closed, it must seal the combustion chamber from the intake port.
Intake Valve
Allows waste gases to be removed from the combustion chamber. When closed, it must seal the combustion chamber from the exhaust port.
Exhaust Valve
Responsible for the opening and closing of the engine’s intake and exhaust valves. The camshaft turns at one-half the speed of the engine’s crankshaft.
