There are a lot of the latest technologies in automobiles:

For example, about the overall fuel:

Hybrid. Hydrogen engine.

diesel engines and so on.

About gasoline engine fuel-saving technology.

Lean burning. Layered combustion.

Six-stroke engines and so on.

About the transmission:

Continuously variable transmission.

DSG dual clutch.

You can find one in the search: the automotive frontier section talks about the latest automotive technology.

Hope it works.

In-cylinder direct injection, Valvetronic electronic valves, Double-Vanos valve timing system, electronic pressure relief valves. These are the current mainstream technologies, which are basically controlled by a few large manufacturers. For example, the latest BMW M3 turbocharged engine is a combination of the above technologies, the official announcement of fuel consumption is not higher than 9L per 100 kilometers, the landlord can think about what kind of concept this is.

New energy vehicles! Diesel-electric hybrid system! Solar Cars!

1.Electronically monitored braking technology. With this technology, the braking distance can be reduced by up to 50%.

This intelligent braking device receives information at the moment of emergency braking of the driver, assists in manually increasing the braking force, and continues to brake even when the driver releases the brake pedal in a panic.

2.Anti-slip system. In order to prevent the loss of direction and rollover accidents during emergency braking, major automobile manufacturing companies have developed anti-skid systems in addition to equipping anti-lock braking systems (ABS) on automobiles, which can be used in conjunction with ABS.

When the car brakes urgently, the anti-skid system can brake each wheel in a few microseconds to stabilize the direction of the vehicle.

3.Four-wheel drive system. In the past, four-wheel powertrains were mostly installed in off-road vehicles and racing cars, but now this system has been introduced in some cars.

The system can be driven by two-wheel power or four-wheel power according to the road surface conditions of the car, and can also detect the contact between the tire and the ground, as well as the tire temperature, inner tube pressure and tire damage.

4.Chassis lift system. This directional adjustment system ensures that the distance between the vehicle and the ground during travel is constantly adjusted with the speed of the vehicle to improve the cushioning capacity and meet the highest safety and comfort requirements.

5.Directional speed and distance adjustment system. The car is equipped with a radar detection system called AAC installed in the car, which can accurately detect obstacles in the car's movement, and transmit the information to the braking system in time to take deceleration measures and reduce the driving force.

As soon as the obstacle is gone, the system automatically debrakes and increases the speed of the vehicle.

degree visual field system. This camera system works in conjunction with a radar system to provide the driver with a timely indication of the dangers surrounding the car while it is moving. In addition, the system assists the driver in parking safely and avoiding collisions.

Extended Materials: New Automotive Technology is a professional book dedicated to introducing the new technology of modern automobiles, which is based on automotive electronic control technology, and systematically introduces the new technologies adopted by modern automobiles from the aspects of engine, chassis, body, safety, environmental protection, and materials. The content is novel, simple and easy to understand, and is suitable as a teaching material for students in colleges and universities and vocational and technical colleges (schools) and a reference book for professionals.

Now most of the new energy vehicles developed are electric, gasoline is a limited resource, a large amount of combustion will lead to a large reduction in oil resources on the earth and will not be regenerated, with a new energy type of energy to target the source of the car can be a large amount of reduction in the use of gasoline, has an important role in fuel-saving technology.

The effective way to save fuel is: you need to grasp the speed, but also need to reduce the weight of the car, ensure that the tire pressure is normal, reduce the frequency of braking, turn on the air conditioner less, pay attention to avoid stepping on the accelerator and braking suddenly, and maintain a reasonable gear. Ways to check your car's fuel consumption:

Most on-board computers will give the average fuel consumption value, which is displayed on the dashboard, but there is usually a certain discrepancy with the actual fuel consumption. Imaginary fuel consumption refers to the fuel economy index of the car when driving at a constant speed on a good road surface, because the constant speed driving is a basic working condition for the car to run on the highway, and this fuel consumption is easy to measure, so it is widely used.

1.Make sure the tire pressure is correct. Not having enough gas or too much gas will increase the fuel consumption of the car, so you should check the tire pressure regularly.

According to the U.S. Department of Energy, as long as the tire pressure in each vehicle is 1 ps (pounds in inches) less than the standard air pressure, the United States consumes an additional 15 million liters of gasoline per day.

2.Switch to fuel-efficient tires, but don't change the tire size at will. Choosing wider tires may make your car look stylish, but the wider the tires, the more wheel drag, so unless you really need that extra grip, you're wasting your gas money.

3.Check regularly that your steering wheel and tires are aligned. When the car is old, the tires and steering wheel tend to be out of alignment, which also consumes fuel.

4.Use the lowest viscosity oil, and your car manual should have a description of the lowest viscosity oil that can be used in the car. The lower the viscosity of the oil, the more "labor-saving" and fuel-efficient the engine is.

5.Take good care of the engine and fix it immediately if there is a problem. Because no matter how big or small the problem is, it will reduce the efficiency of the engine and waste your gas.

6.Protect the body. A dent in the body increases the resistance to the airflow that the car encounters while driving. In addition, those flashy over-decorations will also increase the resistance.

You can try the "grinder" engine curing agent, grinder - engine nanoalloy curing agent in the engine work at the same time to maintain and repair the wear, improve the cylinder pressure of the engine, restore the performance of the engine, make the fuel fully combusted, can reduce carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides and particulate matter (PM) emissions, reduce the engine harmful exhaust emissions by more than 50%, save fuel and electricity by 5%-25%, and extend the service life of the engine by 1-3 times. and creating a third way to solve harmful tailpipe emissions, effectively achieving energy conservation and emission reduction.

Briefly talk about a few fuel-saving techniques for reference:

1. Regularly inspect and maintain the car.

Maintenance and fuel consumption actually have a big relationship, poor maintenance of engine fuel consumption increased by 15%-20%, so the engine should be regularly maintained.

2. Minimize the load on the car.

Excess things on the car will increase the weight of the car, which will increase fuel consumption, if you want to save fuel, we must clean up unnecessary objects on the car in time, reduce the weight of the car, will help to save fuel.

3. Use fuel additives to help save fuel.

We all know that even if the fuel consumption is reduced by 100 kilometers, an average tank of oil can save 30-40 yuan of fuel costs, and for cars with carbon deposits, 100 kilometers of fuel consumption may be reduced by 1 bottle of additives.

4. Maintain reasonable tire pressure and air conditioning temperature.

Maintaining a reasonable tire pressure can help save fuel. Usually, car manufacturers will give a recommended tire pressure inflation value, which is generally in between, so as to ensure both comfort and fuel consumption.

5. Prioritize the use of energy-saving mode.

Today's vehicles offer a variety of driving modes, with some offering three driving modes: Standard, Eco and Sport.

6. Smooth driving, not arrogant or impatient.

During rapid acceleration, the fuel supply to the engine's fuel supply system suddenly increases, resulting in a thick fuel mixture, which causes insufficient fuel combustion and fuel waste.

7. Reduce the number of brakes.

The brakes must not be too fast, otherwise it will be a waste of oil. In the process of driving, if you need to brake in front, you can release the accelerator in advance to let the vehicle move by inertia, which is fuel-efficient at this moment.

It's a pleasure to serve you, I'm a senior teacher Xiaolong, I'm typing the answer, please wait.

The most important thing is the air intake filter, which should be maintained and replaced frequently.

Maintain adequate air pressure in the tires.

Whether it's a manual or automatic transmission, don't accelerate sharply when you step on the accelerator.

Use neutral coasting appropriately.

Then there is the driving habit, don't keep the speed too fast when driving in the city.

When you notice a red light, you start to slow down and slide.

Fuel-saving technology for car driving, such as limiting the speed in advance when the speed limit is approaching, not stepping on the brakes to ensure safety, changing gears smoothly, and each gear of the manual transmission has a corresponding speed, do not overspeed or drive at low speed.

Press the accelerator lightly and drive smoothly.
