Engine Parts Buying Guide: Frequently Asked Questions
What are the Main Parts of an Engine?
A block, a cylinder head, and cylinders.
What Others are There?
At least one piston per cylinder, plus valves, a valve cover, a camshaft, a crankshaft, spark plugs, and an oil pan (or sump).
What Does Each One Do?
The valves, valve cover, and cylinder head seal the engine; you'll find them on top of the block. Valves -- more specifically, intake and exhaust valves -- regulate the ratio of air to fuel the engine burns for power, and regulate the fume levels inside the engine, respectively. Valve covers protect valves specifically, and cylinder heads keeps gas and oil from leaking.
The camshaft, however, coordinates the activity of the valves. Engine pistons compress gas and oxygen as they pump, making more potential energy available for combustion. Spark plugs ignite the mix initially, and it burns, producing power. The crankshaft turns that power into rotational motion, and the drive shaft and transmission transfer that motion to the wheels and tires.
The oil pan or sump stores motor oil for lubricating everything. Many other parts -- gears and sprockets, rings, bearings, and more -- fit everything together correctly.
What Happens When One Wears Out and Goes Bad?
You'll start to have engine problems, almost invariably. The signs of them include everything from acceleration and idling issues and worsening fuel efficiency to stalling and being unable to start your vehicle at all. See any of these, and you may need to make repairs. Our auto parts store has what you need for the job: genuine parts, straight from your manufacturer.
