Mazda Engine Parts Buying Guide

The Main Parts of an Engine

Whether you drive a Mazda car or one of the brand's SUVs, its engine will have a block, a cylinder head, and cylinders.

Other Important Ones

Most engines have at least one piston per cylinder, plus valves and a valve cover, a camshaft and crankshaft, spark plugs, and an oil pan or sump.

What Each One Does

The valves, valve cover, and cylinder head help seal off the engine; they're all located on top of the engine block. Valves -- more specifically, the intake and exhaust valves -- regulate the air-to-fuel ratio the engine burns for power and the fume levels inside the engine, respectively. Valve covers protect the valves specifically, and cylinder heads keep both gas and oil from leaking. The camshaft coordinates the valves' activities.

Engine pistons, however, compress gas and oxygen as they pump, which makes more energy available for combustion. Spark plugs ignite that mixture initially, and it burns, producing the power the engine runs on. The crankshaft transforms that power into rotational motion, and the drive shaft and transmission transfer that motion to the wheels and tires, turning them.

Finally, the oil sump or pan stores motor oil for lubricating it all. Many other parts -- from gears and sprockets to rings, bearings, and more -- make sure everything fits together correctly.
