Audi Auto Engine Parts Catalog

Audi is a luxury car from the house of Germany's leading and oldest auto manufacturer - the Horch & Cie Company. Audi has survived the industry for more than a century and is still operational and dependable, working hard to give us one of the finest fleet of automobiles. Audi cars are also well known, the world over, for their performance. Audi has not only managed to create its own identity but has also earned the respect of other car makers and customers alike. Its symbol of the "Four Rings" is the mark of one of the oldest car manufacturers in Germany. The combined technology and styling injected to every Audi make it a product of achievement.

The primary purpose of the Audi engine is to transform the air and petrol into rotary motion so that it can drive the wheels of the car. The engine has pistons which move up and down in the cylinders. Above the piston is the combustion chamber while on the other side is the crankcase, full of oil. Pistons have rings which serve to keep the oil out of the combustion chamber. Connected to the pistons through a connecting rod is the crankshaft. The up and down movement of the piston in the cylinder rotates the crankshaft and transforms the straight line motion into rotary motion.

The valve train consists of valves, rocker arms, pushrods, lifters, and the camshaft. The purpose of the valve train is to let the air and petrol in and out of the engine at the proper time. The camshaft coordinated to the crankshaft by a chain or belt controls the timing. Vacuum is created when the camshaft opens the intake valve and the piston moves down the cylinder. As a result of this, air and petrol is sucked into the combustion chamber above the piston. The intake calve closes and the combustion chamber gets sealed when the piston begins to move back up the cylinder. The compression of the fuel and air as the piston reaches the top of the cylinder causes the spark plug to fire and ignite the fuel and air. The flare-up pushes the piston back down the cylinder and drives the crankshaft.

The rings of the Audi engine pistons can tend to wear over a period of time which dilutes the oil. The oils dilution results in the oils inability to lubricate the Audi engine causing premature wear.
