Small but helpful

After more than 75 years in the automobile industry, German automotive giant Audi continues to produce exquisite, sophisticated, and technically sound vehicles. No matter how profound these qualities are, Audi still relies on function engine components to bring the goods. For example, consider the engine startup and ignition. The initial step for a car to move is by switching it on. To this end, Audi Relay acts as the electrical switch that opens and closes under the control of another electrical circuit. The starter solenoid of an Audi controls the high-current circuit with a low-current signal, which in a broad sense, is a form of an electrical amplifier.

Once in motion, Audi cars, like any another automobile with an internal combustion engine, have to keep their temperature at bay to avoid overheating – a function performed by the radiator. Although singularly important, a radiator needs its subparts to work hand-in-hand with the whole system. One significant part of an Audi cooling system is the Audi radiator hose, which acts as a passageway of fluid from the radiator to the engine and the cylinder head. A mixture of water with ethylene glycol or antifreeze passes through the radiator hose. As this liquid passes through the pipes or hoses, it absorbs the heat, thus cooling the engine. The fluid leaves the engine, passes through the radiator which transfers the heat from the fluid to the air blowing through the exchanger, and goes back into the system through, again, the radiator hoses.

Making sure that even the most fundamental parts such as the Audi relay and Audi radiator hose are produced in crispest condition possible is one of Audi's guiding principles in manufacturing their vehicles. After all, Audi’s claim to excellence can easily be put to waste with disregard of the basics.
