Automobiles that we drive today are an excellent example of expert and precision engineering. Ever since its invention which is believed to have been made by Nicolas Joseph Cugnot, automobiles have gone through a series of modifications and re-inventions in a hope of building the ultimate automobile for the people around the globe. Let’s accept the fact that automobiles have now become an integral part of our lives and it would be difficult to imagine a life without a self-propelled vehicle. Although initially, automobiles were fairly easy to understand as they had very few parts, today the story is very different. With improved technologies and inventions, vehicles today are not merely a source of transportation but are much more than that. As more and more conveniences and accessories are added into automobiles, they have become more complex to understand. To overcome these complications, automobiles are now sub-categorized into number of systems that actually combine together to make the modern day automobile a reality.
Although each independent system is equally important for any automobile, if we arrange these systems according to the priority, it is the engine which gets the top listing. The engine is the component that actually generates the necessary power to propel the vehicle and affects every other system which makes up an operational automobile. Even though the engine does require other dedicated systems to work along with it for the most efficient operation, it still remains the single most important system. But an engine which is designed to generate continuous power by burning the fuel needs to be initiated first (usually with an electric starter motor) and also needs an efficient system for supplying the fuel to the combustion chamber as well as electricity to generate an ignition source for the combustion process. There also needs to be a system to control against the buildup of excessive temperatures resulting from the combustion process. So the ignition, electrical, fuel supply and cooling systems all find their importance in the priority list right after the engine. In addition, the by-products of the combustion process also need to be successfully evacuated from the engine cylinders without actually polluting the environment, so the exhaust system is a must. Moving further, the engine which has developed power needs a proper channel so that it can be easily and smoothly be transmitted to the wheels and provide the actual propulsion of the vehicle. This is accomplished with an effective transmission system. But that’s not all; the vehicle which has the ability to travel using engine power is of no use if it cannot be maneuvered, so the vehicle needs an efficient steering system which would help the vehicle to negotiate a turn when there is a need. While the braking system controls the vehicle speed by slowing or stopping the vehicle, the suspension system ensures that these systems mentioned above do not get affected by the uncertainty of the road conditions on which the vehicle travels. Without a sustainable suspension system, vibrations and shocks developed from the uneven road surfaces would misalign all the vehicle parts and on top of that would give a strong sign of discomfort to the passengers. It would be appropriate to include the safety restraint system in the priority list of automotive systems today as driver and passenger safety has become more important than any other technological advancement. Today vehicles are designed with utmost care and are equipped with every possible safety feature to ensure that driving today’s automobile remains safe and enjoyable.
These systems are composed of numerous parts combining together to form the systems that together form a modern day automobile, designed not only for mobility but for luxury, comfort, style statement and safety.
