Explanation of the basic common sense of car novices

1. When changing the lane (parall line) while driving, you should not only turn on the direction lights in advance to warn the rear car, but also carefully observe the reflectors on both sides to see clearly Whether there is a car behind it, especially whether there is a car behind it in the lane to enter. If there is, either accelerate the distance by yourself and then enter the lane, or wait for the car behind you to pass.

2. Second, novices should understand how to remove fog. Glass fog is generally in the early morning or winter. Due to the temperature difference inside and outside the car, a small water droplets are formed on the windshield, and the use of a wiper does not have a good effect.

3. Wheelbase mm from the center of the front axle of the car toThe distance between the center of the rear axle is 2 turning radius mm. When the car turns, the center plane of the outer steering wheel of the car is the trajectory circle radius on the vehicle support plane. When the steering disc turns to the limit position, the turning radius is the minimum turning radius 3, the maximum total mass kg, the total when the car is fully loaded.

4. Novice drivers must know the common sense of cars. The wheelbase is the distance from the front wheel to the rear wheel of the car. The larger the wheelbase, the larger the space in the car. The higher the gasoline number, the higher the octane number, the stronger the explosion resistance, and the slower the combustion, because the size of the octane number determines the ability to resist explosion. The higher the label, the better, and it should match the engine.

5. Automobile Knowledge mdash Novice Introduction 1 Automobile Structure Automobile is not born as a whole, but an overall shape composed of various parts, among which ldquo chassis rDquo plays an important role, supporting the body and the engine and its parts. The chassis is composed of four parts: the transmission system, the steering system and the braking system.

6. The quality of the whole vehicle rubber equipment (KG): The quality of the car is fully equipped, that is, the quality of the manufacturer's factory, including the quality of various lubricating oils, oils, car tools, spare tires, etc. It is usually what we call empty load mass and vehicle weight. Maximum total mass (KG): the total mass when the car is fully loaded. The total mass when sitting full of people and full of goods.

Explanation of automatic transmission car gear

1. Automatic transmission car gears include P gear, R gear, N gear, D gear, S gear and L gear. P is Parking, and the car stops.After that, the P gear vehicle is to brake to prevent movement. Unlike the N gear, the P gear interrupts the power output. At present, some models will have independent P gear, which is called electronic braking, and the principle is the same.

2. When waiting for the traffic light, you should pull up the handbrake at the same time, and disable the gear when going downhill. L gear: This gear can be used when going downhill or uphill. It can limit the gear of the car to the lowest gear, so that the car can use engine power to brake when going downhill. The driver does not need to step on the brake for a long time, causing the brake pads to overheat and cause danger.

3. The explanation of the gear of the automatic transmission car is as follows: D gear: This is the most commonly used gear of the automatic transmission model. There are usually three types of DDD3, which are similar to the 1 and 2 swings, 3 and 4 gears, 5 and 6 gears of manual transmission. Different types of gears do not need to be controlled manually, and the car will adjust according to the accelerator. Up and down gear.

4. Reverse gear, reverse gear. It is used when reversing. None, neutral. Use this gear when parking temporarily (such as a red light). Note that this gear indicates an idle gear. In order to prevent the vehicle from slipping on the slope, you must step on the brakes. Forward gear, also known as active gear. Needless to say, use this gear when moving forward.

The gear and usage method of automatic transmission cars

The gears on general automatic transmission cars are: P (parking gear), R (reverse gear), N (idle gear) and D (forward gear). P gear; how to use the parking gear.

Explanation of the gear of automatic transmission vehicles The gears of automatic transmission vehicles include P (parking gear), R (reverse gear), N (idle gear), D (forward gear), S (sports mode), etc. P gear parking gear, when the vehicle stops, the gear needs to be hung on the P gear, including turning off the engine and long-term idling stop. R gear reverse gear, you need to hang the gear on the R gear when reversing.

The gear tutorial of the automatic transmission car is as follows: p gear, this is the parking gear. When the vehicle stops, hanging in the p gear position can avoid the vehicle from moving. M gear, this is a manual mode, and only the manual and automatic integrated models will have it.Among them, the + sign represents gear increase, and the - sign represents gear reduction.

D gear This represents the forward gear, which is often used in automatic transmission models. Generally, in the process of driving the vehicle, the gear is in the D gear position, so as to ensure that the vehicle can move forward normally. L gear This is a low-speed gear, which is generally used when vehicles go up and downhill.

The gears of automatic transmission cars have P, R, N, D, L, etc., and their usage methods are as follows: P gear: press and hold the brake pedal and move the push switch to P gear, which can keep the vehicle stationary. R gear: Press and hold the brake pedal and move the push switch to R gear, which can start to reverse, that is, reverse backwards.

3 interesting car cold knowledge, let's see how many you know?

1. An interesting knowledge of car cold traffic lights. When it comes to traffic, traffic lights are indispensable. Does anyone know what traffic lights are and who invented them and when? In fact, traffic lights were born 18 years earlier than cars.

2. The antenna on the top of the car. Many people summarize the role of the antenna of the car (that is, the vertical line on the top of the car) as a radio receiver. Indeed, this is one of them, but not all of them. The role of the car antenna is also reflected in the GPS, which is used to show people the way, and the antenna on the police car also plays the role of transmitting commands.

3. A few cold knowledge about cars. Driving is not unfamiliar to drivers. Here are a few cold knowledge about cars, some of which even veteran drivers who have been driving for many years may not know!Airbags also need to be replaced. In theory, the design life of car airbags is the same as the service life of the whole vehicle.

4. How much do you know about the top ten car cold knowledge? Let's talk about the origin of the English name "Sedan" first.

5. First of all, there will be a small cover on the handle of the door. If we gently pry it off with the key, we will see the keychain, so that we can open the door. Then stick the powerless car key to the one-click start button, and then step on the brake to start. The above is some cold knowledge about cars that the editor knows.
