What You Should Know About Automobile Parts?


The invention of the automobile is the most influential in modern history. It has had a significant impact on many aspects of history, economics, and social life around the globe. The automobile is directly responsible for the United States’ rapid growth in the 20th century.

Automobiles are used in every facet of society. From the design of cities to personal use such as shopping, vacation, dining, and travel, they can be found everywhere. The mass-production techniques that were originally developed for automobiles have been modified for almost every industry. Numerous industries depend on the automobile directly and indirectly. These include steel, other metals, plastics rubber, glass, fabric, petroleum products, and electronic components.

The Structure Of The Car

The essential parts of the modern car are made up of hundreds of parts. These parts, much like the human body are organized into many systems with different functions. Each system is essential for the vehicle to run safely, reduce noise pollution, and keep it running smoothly.

The engine, transmission, fuel system, and exhaust system are the major components of an automobile. The chassis is composed of the tires and wheels, brakes, suspension, body, and suspension systems. They will be found on every type of motor vehicle.

Engine. The engine, the “heart” or the heart of an automobile, operates on internal combustion. This means that the fuel used to generate its power is burned within the engine. The combustion takes place inside the cylinders that contain pistons. Through a connecting rod, the pistons are connected to a crankshaft. The vacuum created by the piston moving down the cylinder pulls gasoline, the most popular automobile fuel, into the cylinder. The piston’s upward movement compresses the gasoline into the cylinder. The spark plug is placed at the end of the cylinder. The spark causes gasoline to explode and drives the piston back down into the cylinder. This is called the power stroke and turns the crankshaft. The final movement of the piston upward forces the exhaust gases (byproducts of fuel’s combustion) from the cylinder. These four movements, which are called strokes, are intake, compression, power, and exhaust. The most popular type of automobile engine is the four-stroke.

Fuel System. Before gasoline can be put into a cylinder, it must be mixed properly with air. Combining gasoline with air produces a stronger explosion. The fuel pump pulls the gasoline from the tank at the rear of your car. Some cars have the gasoline drawn into a carburetor, while others use fuel injection. The devices combine gasoline and air (approximately 14 percent of gasoline to 1 percent of air) and spray the mixture into the cylinders as a fine mist. The fuel system also includes the intake manifold, which distributes the fuel mixture to cylinders.

Exhaust System. To make space for the next intake, gases and heat must be released from the combustion chambers after the fuel has been burned. The exhaust system also reduces the noise from the fuel’s explosion.

An exhaust valve releases the exhaust gases from the cylinder. The exhaust gases collect in an exhaust manifold, before being channeled through the exhaust pipe to the muffler and out the tailpipe. The muffler has a maze made of baffles. These specially designed walls absorb heat, force, and sound as the exhaust passes through them.

Burning fuel produces hazardous gases (hydrocarbons and carbon monoxide) which are extremely dangerous to engine components and the environment. The car’s exhaust system is linked to its emission control system. It functions in two ways. It reduces unburned fuel levels by burning as much exhaust as possible. This is done by returning the exhaust to the fuel-air mix injected into the combustion chambers. It also uses a catalytic converter (which is fitted before the muffler) which increases the conversion of harmful gases to less harmful forms.

Lubrication. The heat and friction caused by the engine’s rapid movements would quickly cause its failure without proper lubrication. The crankcase is located at the engine’s bottom and holds an oil supply. The engine’s crankcase houses an oil pump that transports the oil through various passages and holes to the engine’s various parts. The oil forms a thin layer of oil between moving parts as it flows through the engine. The hot oil is drained back into the crankcase where it cools. The crankcase’s fumes are circulated by the positive crankcase ventilation (PCV) valve back towards the cylinders. They are then burned off to reduce the pollution.

Transmission. The crankshaft can spin only within a narrow range of speeds, typically between 1,000 and 6,000 revolutions per hour (rpm). The wheels spin at a lower rpm, but the range they can spin is greater to accommodate the wide range in automobile driving speeds. Transmission gears reduce the crankshaft’s fast-spinning input to the wheels by reducing the number of rooms required.

There are two types: automatic and manual. Most automobiles have at least three gears plus a reverse (many manual transmissions have up to five gears). The driver controls the shifting of the gears in a manual transmission. An automatic transmission engages the gears automatically. Both types of transmission use a clutch to allow the gears of both manual and automatic transmissions to be engaged or disengaged.
