How long does a car last? After more than 15 years of car, can it really not continue to drive?

With the rapid development of society and economy, the automobile has gradually become the preferred means of transportation for people to travel. Nowadays, the attributes of the car are not only used as a means of transportation, but also mixed with attributes unique to modern society such as social interaction. Cars are like bicycles of the last century, and houses have become "big items" that must be used to live a life.

But the car is fundamentally different from the house, the car is actually a kind of consumable. A new car starts to depreciate from the moment you drive out of a 4S shop, and the life of a car is not as long as a house for hundreds of years. So how long exactly does a car last? Is it true that there are also rumors that cars older than 15 years cannot continue to drive?

The development of the automobile

The great physicist Newton, as early as 1680, proposed whether it was possible to replace a carriage or rickshaw with a machine, and he imagined a car driven by nozzle jet steam, but due to the limitations of technological development at that time, it was not invented by Newton.

The true birth of the automobile was based on the invention of the steam engine of the first industrial revolution, and in 1769 the Frenchman Newt built a three-wheeled car that relied on coal combustion to produce steam, similar to the old-fashioned steam train. But the car could only reach a speed of 4 kilometers per hour, or even faster than a human walk, and because it needed to burn coal to produce steam, people had to stop and fill the furnace with new coal after fifteen minutes of driving. This runs counter to the original intention of facilitating people's travel, but it also provides the basis for the development of automobiles after that.

In 1879, the German Carl Benz successfully developed a two-stroke engine, and the second industrial revolution led to the invention of the internal combustion engine, relying on this technology he successfully developed a three-wheeled car in 1885. The car is already beginning to have some of the basic features of the modern automotive industry, such as the use of spark ignition, steel frames, spring suspension, rear-wheel drive front wheel steering and handlebars. This is the predecessor of mercedes-benz cars, which are now the world's famous car companies.

Since then, the automobile has entered the era of the internal combustion engine. Instead of filling bulky coal into cars, people are replaced by gasoline that burns more efficiently and is more environmentally friendly.

But the Industrial Revolution brought with it a lot of pollution along with steam engines and internal combustion engines, and people were considering whether it would be feasible to use more environmentally friendly electrical energy to drive cars. Invented in 1881 by the Frenchman Gustav Truff, the first electric car was powered by a lead-acid battery, and the battery was disposable.

However, with the development of oil extraction technology and the maturity of internal combustion engine technology after 1920, electric vehicles entered a period of nearly a hundred years of silence. In recent years, with the emergence of global environmental problems caused by environmental pollution, people seem to think of electric vehicles that are about to be forgotten.

As a result, in recent years, nickel-cadmium batteries, nickel-metal hydride batteries and other new energy vehicles as electricity have gradually appeared. Many car companies have also announced that they will stop selling fuel vehicles one day in the future. And some scientists have begun to study the hydrogen fuel as the power of the car, hydrogen combustion efficiency and calorific value are higher than gasoline, and the combustion product is only water, is undoubtedly the most ideal clean energy now.

But more people are concerned about the service life of the car than how the car will develop, so how long can a car drive? Is the rumored 15 years correct?

Factors that affect the life of a car

Automobiles are a combination of complex industrial technologies with complex mechanical structures. In fact, the most important thing that affects the life of the car is the life of these mechanical structures. Let's analyze how these mechanical structures affect the life of the car.

First of all, the most important component of the car is the engine, which is equivalent to the heart of a car. It is composed of cooling system, fuel supply system, lubrication system, ignition system and starting system. If there is a problem with the cooling system, the engine temperature will remain high and there is a risk of spontaneous combustion.

Lubrication system is generally to provide lubrication oil for the engine, keep the engine has been smooth movement, if the lubrication system is a problem, then the engine components are easy to rub and crash caused damage.

The fuel supply system is responsible for fueling the engine, and only a steady stream of fuel engines can work all the time. The start-up and ignition system is responsible for generating an electric spark that ignites the fuel and drives the engine into motion.

Secondly, the chassis is also a very important part of the entire structure of the car, which is the part that supports the car, installs the various components of the car, and ensures the normal operation of the car. The chassis consists of five parts: transmission system, driving system, steering system, suspension system and braking system.

The transmission system is an important system that cooperates with the engine to drive the entire vehicle, and the entire driving state of the car is determined by the transmission system, once there is a problem with the transmission system, the car will not be able to transmit power to the wheels.

In addition, the gearbox on the car transmission system is one of the most important components of the car, it determines the power of the car, the structure of the gearbox is quite complex, so the quality of the gearbox determines whether the car can drive, and the life of the gearbox determines the life of the car itself.

The driving system is responsible for bearing the weight of the vehicle and driving the power to the wheels. The role of the steering system is to be responsible for the direction of the vehicle, if the vehicle's steering system is wrong, then the car must not be able to drive normally on the road.

The suspension system is used to absorb the impact force of the ground facing the vehicle, determines the passing ability and comfort of the vehicle in driving, and is generally composed of a spring structure.

The importance of the braking system is self-evident, in short, it is to slow down the vehicle or even stop the role, once the braking system has a problem, then the life of the driving personnel will be greatly threatened.

The life of the car body also determines the life of the car. The body is generally a one-piece cast structure, cast in high-strength steel. The strength of the body is related to the safety of the passengers, and the body is generally covered with anti-corrosion paint. Since the body is integrally cast, when a car crashes, the body steel is often deformed. The force distribution of each part of the car changes, which may affect the overall structural strength of the body, and if the body is hit again, it may cause serious injuries to the passengers.

At present, in order to protect the safety of passengers, the vehicle is also equipped with seat belts, airbags and other protective devices. On a certain degree of impact, it will reduce the fatal injury of the driver and passenger.

Finally, tires are also one of the most important components of the car. It provides grip for the car as it travels and bears the weight of the car. Once the tire wear is serious, the grip of the vehicle will be greatly reduced, and accidents such as skidding and rollover will occur.

Can a car live longer than 15 years and cannot be driven?

The answer, of course, is no, but it also depends. In 2013, the mainland implemented a new motor vehicle scrapping policy. It stipulates that taxis will be forced to be scrapped for 8 years, or if the total mileage exceeds 600,000 kilometers. There is no mandatory scrapping age for private cars, but a mileage cap of 600,000 kilometers is also set. For ordinary families, the total mileage of a private car a year is about 10,000 to 30,000 kilometers, and it takes 20 or 30 years to reach the mileage limit of 600,000 kilometers.

Theoretically, as long as your vehicle can pass the national vehicle annual inspection normally, the number of kilometers can go on until less than 600,000 kilometers. Of course, this is only an idealized state, and the car, as an industrial product, cannot always be perfect.

So how to extend the life of the vehicle? It's what a lot of people want to know now.

In fact, the modern automobile industry is actually a relatively mature industry, as long as the standard use, there will be no major problems, but with the increase of the age will certainly have some small problems continue to emerge.

Car like love your own loved ones, in order to extend the service life of the vehicle. For example, violent driving or irregular driving will cause damage to the engine and gearbox, which in turn will affect the service life of the vehicle. Do not often clean the dust and dirt on the paint, may cause damage to the paint, modern car paint is mostly with anti-corrosion function, once destroyed, may accelerate the corrosion of the vehicle steel structure, and then affect the strength of the body.

In addition, on-time maintenance is also a good way to increase the service life of the vehicle. Regular maintenance of the vehicle, replacement of regular brands and models of oil, do not greedily use some inferior or counterfeit products, and then cause irreversible damage to the engine, the price of repairing the vehicle is much more than the money they save, it is somewhat too much to lose.

And there are also some wearable parts on the car, such as spark plugs, wipers, brake pads, filters, tires, batteries and so on. These must be checked from time to time, find problems and replace them in time to avoid accidental life threats when driving.

Although the vehicle is not more than 15 years can no longer be used, but when the vehicle reaches the scrapping conditions or has experienced a large accident, it should be scrapped in time, do not hold a fluke mentality, so as not to pose a threat to their own life and safety.
