Examples include sedans, trucks, buses, trailers, and incomplete vehicles, each being a separate category. 2. Others: Heavy-duty vehicles have a length of 6 meters or more and a total mass of 12,000 kg or more. Medium-duty vehicles have a length of 6 meters or more and a total mass between 4,500 kg and 12,000 kg. Light-duty vehicles have a length of less than 6 meters and a total mass of less than 4,500 kg. Mini vehicles have a length of 3.5 meters or less and a carrying capacity of 1,800 kg or less.
Since childhood, I've been fascinated by machinery. To me, a car is essentially a powered mechanical device capable of self-propulsion. It generates motion through an engine or electric motor, transmitting power via gears and wheels to transport people or goods from one place to another. The core components include the internal combustion engine (fueled by gasoline or diesel), transmission system, chassis structure, braking mechanism, and electronic control systems – all working in harmony to ensure smooth and safe operation. Modern vehicles incorporate intelligent features like navigation and autonomous driving assistance. Understanding automotive fundamentals has become my daily hobby, often recalling these details when helping friends with basic repairs. It's not merely transportation; it's more like a sophisticated engineering marvel that makes our lives more convenient and efficient.
I drive to and from work every day, and it's been almost ten years. For me, a car is simply a means of transportation that allows me to quickly reach the office, supermarkets, or travel destinations, saving me the hassle of crowded buses. It shields me from wind and rain during bad weather, provides air conditioning in summer and warmth in winter, and conveniently carries my personal belongings. Simply put, a car is a metal box with four wheels, equipped with a steering wheel, accelerator, and brakes to control direction and speed, while the engine powers it. I've driven several cars, from old manual transmissions to automatic ones, and I feel that a car is a helper in life, improving quality of life. However, it requires regular maintenance, refueling, and inspections, or it can easily break down.
I've read many books on automotive history. The automobile was initially invented in the late 19th century by figures like Karl Benz, replacing horse-drawn carriages as the mainstream mode of transportation. By definition, an automobile is a human-made wheeled vehicle, originally powered by steam or gasoline, which has now evolved into various forms including internal combustion engines and electric vehicles. It symbolizes the progress of the Industrial Revolution, with Henry Ford popularizing it through assembly line production. For me, studying these topics is quite fascinating—cars are like time capsules that document human innovation.
