Internal Engine Parts are the foundation of reliable engine performance, directly influencing power, efficiency, and longevity. Whether you're seeking OEM replacement components for precise factory fit or performance upgrades to push your vehicle's limits, choosing parts with durable construction is essential to withstand demanding conditions. This selection includes vital elements such as pistons, crankshafts, camshafts, bearings, and timing components—all engineered to deliver superior function and peace of mind mile after mile.
Let's look at some key engine parts in more detail.
Spark plug
The
spark plug supplies the spark that ignites the air/fuel mixture so that
combustion can occur. The spark must happen at just the right moment
for things to work properly.
Valves
The
intake and exhaust valves open at the proper time to let in air and
fuel and to let out exhaust. Note that both valves are closed during
compression and combustion so that the combustion chamber is sealed.
Piston
A piston is a cylindrical piece of metal that moves up and down inside the cylinder.
Piston rings
Piston
rings provide a sliding seal between the outer edge of the piston and
the inner edge of the cylinder. The rings serve two purposes:
Connecting rod
The
connecting rod connects the piston to the crankshaft. It can rotate at
both ends so that its angle can change as the piston moves and the
crankshaft rotates.
Crankshaft
The crankshaft turns the piston's up and down motion into circular motion just like a crank on a jack-in-the-box does.
Sump
The sump surrounds the crankshaft. It contains some amount of oil, which collects in the bottom of the sump (the oil pan).
These are all components of an engine that you need for it to function properly. All can be found here at Sam's Motorsports.
