Components, Engines, and Safety Features of Automobiles


If you are looking for the information about the Modern Automobiles, you’ve come to the right place. You will find articles on the Components, Engines, and Safety features of Automobiles. You can also learn about the History of Automobiles. But before you start reading about the History of Automobiles, make sure you first understand what they are.

Modern automobiles

Modern automobiles are a complex technical system, with thousands of component parts. Their evolution has been driven by changes in air pollution and safety legislation, and by competition between manufacturers worldwide. In the United States, nearly one-quarter of all vehicles are passenger cars. Today, the automotive industry employs over 14 million people.

The earliest automobiles were developed in Germany and France in the late 1800s. After the First World War, the automobile industry became dominated by Americans. Henry Ford and others helped invent mass production techniques and established the “Big Three” auto companies by the 1920s. During World War II, manufacturers shifted resources to the war effort, but by the end of the war, automobile production had exploded in Japan, Europe, and the United States. By the 1980s, automobile production was a global industry.


Automobiles consist of four essential components: engine, transmission system, chassis and body. The chassis incorporates the moving parts of the automobile, such as the frame, wheels, axles and suspension system. The frame supports the weight of the car, while the suspension system absorbs vibrations resulting from up-and-down movement of the wheels. A car’s body also includes the hood, windshield, and air conditioning system.

The modern automobile is a complex technical system that consists of thousands of parts. These parts have specific design functions and are separated into hundreds or even thousands. This presentation aims to give an overview of the various components that make up an automobile.

Safety features

Safety features in automobiles have come a long way in recent decades. Today, the most common safety features come standard, offering greater protection against accidents. For example, frontal airbags, which have been estimated to save 50,457 lives since 1987, help prevent serious injuries from impacting the head against the dashboard, steering wheel, or side window. These airbags are designed to work in conjunction with seat belts to provide the best level of protection.

Similarly, lane departure warning systems help prevent head-on collisions by alerting drivers to the dangers in their lane. These systems use cameras or sensors to monitor the road ahead and alert drivers with a high-pitched beep. Other advanced safety features include adaptive headlights and infrared night vision.


Automobiles use many different types of engines, depending on the type of car. The main types of engines are spark-ignition engines, direct injection engines, and compression ignition engines. Spark-ignition engines have four different types of combustion chambers. These combustion chambers are named after their shapes when the piston is in the top-center position.

The combustion process of these engines can produce various pollutants, including carbon monoxide and oxides of nitrogen. These pollutants are emitted through the exhaust system, the fuel tank, and the carburetor. These pollutants are harmful to the environment, and legislation has been passed to reduce their production.


Production of automobiles involves several steps. Each step must be carried out at a specific speed and with precision. Controlling the flow of materials from a feeder plant, for instance, is a significant engineering task. Timely shipments by truck or rail are another important task. The total speed of the process must be constant for optimal efficiency of the operators.

The automobile industry in India generates substantial employment opportunities. It employs about 4.5 lakh people directly and over one crore people indirectly. It has also risen its contribution to the economy from 2.77 per cent in 1992-93 to 4.7 per cent in 2002-03. Production centres of automobiles in India are largely located in urban areas.
