Automobiles are the main means of transportation and travelling for people all over the world. Probably more than any other invention automobiles alter the way people live. (Rosmanitz) Cars and other vehicles are a driving force behind many of today’s technological advancements. They are complex machines that improve people’s lives. Even to this day vehicles are a huge advancement in society. They are constantly being improved and enhanced. With this constant upgrading they are becoming more complex and harder to maintain. Understanding this convoluted machinery is very beneficial. To use a car to its full potential depends upon an understanding of how the car operates, acquiring essential maintenance skills, and developing a fuel conscious mindset.
The car operates in a complex way. There are many complicated parts to a car that all must work perfectly together in order to run. “The heart of every car is the engine” (Rosmanitz). The engine is composed of the following main parts: the camshaft, crankshaft, pistons, valves, and the spark plug which help the car run. “A camshaft is the mechanical brain of an engine, responsible for coordinating all the major parts.” It is positioned above the engine head. It is also connected to the crankshaft by a timing chain. The timing is crucial and must be precise. The crankshaft is connected to the connecting rod. It “changes the pumping motion of the pistons into spinning motion.” This is a very efficient way of working the pistons. The camshaft regulates the timing of the opening and closing of the engine valves. (Newton). All parts to a car are necessary for the car to run smoothly and efficiently. The crankshaft and the camshaft both have a purpose, and a necessary part in the system of an engine. The crankshaft effects the movement of the pistons, and the camshaft affects the movement of the valves. They are both mandatory.
There are two types of valves: Intake and exhaust. The valves regulate the stream of fuel through an engine. The camshaft opens the intake valve to let fuel into the combustion chamber, then closes it. The exhaust valve opens and the piston pushes upward to release the exhaust fumes. The intake and exhaust valve timing must correspond with the pistons. Each piston is connected to the crankshaft by a connecting rod. The piston and the crankshaft must be slightly off-centered. This prevents anything from breaking from the downward force of the piston. (Newton). Fuel is pushed into the combustion chamber through the intake valve, a spark plug then ignites the fuel, forcing the pistons in a downward upward motion. (Rosmanitz). The pistons and the valves connected preform a major role in the engine and engine function. Valves and pistons must work in unison. The timing of the pistons and valves are important. The energy being produced from the piston movement is what runs the car.
The engine provides a way for the car to go forward, and the brakes provide a way for the car to stop. “A...
