What is the effect of driving out of gear on the car?

There are two kinds of so-called drag gears: low-grade and high-speed drag; High-grade and low-speed tow. No matter what kind of procrastination, it's not a good sign.

Low gear and high drag, it is easy to make the engine run at too high speed. Each engine has its own specific speed – power characteristics – and once it exceeds the optimum zone, it can cost fuel dramatically, and at the same time, ultra-high speeds can put too much pressure on the engine components.

High-grade low-drag is more troublesome:

First of all, it is easy to stall, and under such working conditions, the engine may work near the critical speed and is easy to stall.

Secondly, if the engine speed is too low, the power output will be weak (or the power-speed characteristics are determined).

Third, the speed is too low, the car does not go out, and the fuel consumption index is calculated according to the standard of 100 kilometers, so calculated, although the fuel consumption per unit time is reduced, but it takes several times to run the same distance, resulting in an increase in fuel consumption.

Fourth, the power output is not enough, and the car has to move forward, and the car is prone to setbacks and damage the gearbox.

Fifth, long-term operation at low speeds, the valve is prone to carbon deposit.

Driving with brakes for a long time will cause the brake pads to produce high temperature due to continuous friction, resulting in burnt brake pads, and the physical properties of the burnt brake pads will not reach the normal friction damping. That is, the brake pads will be scrapped, and the brake pads must be replaced to achieve the standard braking performance. Then there is the increase in the rotational resistance of the propeller shaft when braking.

The throttle had to be increased to reach the normal speed, resulting in a sharp increase in fuel consumption.

It can also break the gears. Gears that are not fully engaged are prone to tooth chipping.

Affects safety (the auxiliary braking effect of the engine is gone). Increase the friction of the parts (the lubrication pressure of some parts will not be enough after the gear is dismounted). Off-gearing and fuel-efficient is a misconception.

When the speed is more than 30 kilometers, release the throttle, if in the gear, at this time the engine is to stop supplying oil, directly rely on inertia to drive the engine to rotate, if out of gear, the engine must also supply fuel to maintain idle operation, so out of gear will only increase fuel consumption.

There is a lot of friction on the gears of the engine.

Damage to the gearbox. Wear gears.

Shifting refers to the automatic disconnection of the transmission back into neutral gear from a certain gear while the car is driving. Shifting sometimes occurs when accelerating sharply, sometimes when decelerating suddenly, and sometimes when the road is bumpy and the car is shaking. This problem often occurred in old cars in the past. It is also sometimes called a gear jump.

Towing refers to the fact that the gear is too high and does not match the actual situation when the vehicle is driving. There are two kinds of so-called drag gears: low-grade and high-speed drag; High-grade and low-speed tow. No matter what kind of dragging, it is not a good phenomenon, it will have a bad impact on the machine, and it will cost oil.

Drag gear, that is, the gear is not reduced when it is time to remove, resulting in a mismatch between the speed and the gear. Drag gear will cause the engine to be seriously overloaded, and the engine, transmission mechanism and even the whole vehicle will shake violently, accompanied by abnormal noise. If it is a diesel engine, the exhaust pipe will emit black smoke, which will cause great damage and impact to the vehicle and engine.

Many people, especially novices, have the habit of dragging gears when driving, not according to the speed and road conditions to choose the right gear, but in order to save trouble, use a gear for a long time, and think that this can save fuel. In fact, according to the principle of fuel saving, whether the fuel is efficient is related to whether the vehicle is in the best working condition. Generally speaking, the lower the gear used, the smaller the throttle opening, the worse the power utilization, and the higher the fuel consumption.

Whenever possible, try to use high gear and drive at a moderate speed. If the vehicle is constantly towed in high gear, it may cause damage to the vehicle.

1. From the load characteristics of the engine, it can be seen that the throttle opening is small, the engine load rate is low, and the fuel consumption is high.

2. The vehicle is often in the state of towing driving, and its clutch, transmission, transmission shaft, differential and other transmission parts, due to continuous impact, will lead to early damage and shorten the service life. At the same time, the noise emitted when towing can be unbearable for passengers.

3. When driving in tow, when you need to speed up immediately to cross the obstacle in case of emergency, although you press the accelerator, the speed cannot be lifted immediately, which may be made.

The danger of low congestion at high speeds, due to the failure to make full use of the kinetic energy of the car, the engine runs at high speed, and the transmission runs at low speed. Suddenly attaching a high-speed car to a low-speed gear will cause the car to run and move the engine, and the sound will change, so it cannot be used for operation. In the long run, this will lead to a significant accumulation of carbon.

It is difficult to exert the full power of the engine when driving at high speeds and low speeds, and it can even cause damage to the vehicle's power system. When the engine works at high gear and low speed, the engine output is weak and the torque is small.

If you want to speed up, you don't have the power to work hard. In the end, a lot of oil was added, but the machine was slow, so it didn't save oil. High gears run at low speeds for long periods of time, and the engine often works near critical speeds.

That is, often working on the edge of stalling, the output power is insufficient, the gearbox does not work properly, and it causes great damage to the gearbox. When working at low speeds, it is difficult to exert the self-cleaning effect of the engine, and it is easy to generate carbon deposits in the engine and the euro, which eventually leads to engine and euro failure.

Trailers raise engine temperatures, power decreases, fuel consumption increases, accelerated component wear, and sometimes the engine stalls or **. When the car is dragged, it accelerates sharply after braking, forcing the carburetor vacuum, mechanical pressurization device, acceleration device, and refueling device to work, increasing fuel consumption. The kinetic energy and inertia force of the vehicle are difficult to play effectively, which will reduce the power and economy of the vehicle, lead to abnormal wear of the engine, cause abnormal impact on the chassis gear, and cause great losses to the vehicle.

Modern car engines are powerful and fast. The driver has the habit of shifting gears, and the engine will wear abnormally, causing abnormal impact on the chassis gears and causing great damage to the vehicle.

Don't think that a trailer saves fuel, but in fact it comes at the expense of the life of the car. When the engine is dragged at low speeds, the engine tends to work at too high speeds. Once the optimal construction zone is exceeded, refueling fuel is consumed.

Ultra-high-speed operation can also exert excessive stress on engine components. The speed of the car is too low to let the car drive when it is towed, and the fuel consumption index is calculated according to the standard of 100 kilometers. In this way, the fuel consumption per unit time is reduced, but it takes several times to run the same street, and the fuel consumption increases.

Personally, I feel that the harm to the car is great, and it is easy to damage the vehicle's engine when out of gear, and it is also easy to cause the vehicle to lose control.

This may lead to wear and tear on the gears of the accelerator, and it will also cause great damage to the vehicle, so don't do this, try not to go out of gear, and the damage to the vehicle is particularly great.

The harm is still quite great, because it is difficult to control the speed of the car, and it is very easy to lose control and cause a car accident.

crankshaft, valve spark plug, piston piston ring and cylinder wall, valve ejector rod top column, crankshaft connecting rod and bearings at both ends; 3. If the power output is not enough, and the car has to move forward, the car is prone to setbacks and damage the gearbox; 4. If the engine speed is too low, the power output will be weak; 5. Flameout, the engine works near the critical speed of the line, and it is easy to stall; 6. Long-term operation at low speed, the valve is easy to lack this carbon deposit. Fuel consumption, the speed is too low, the car does not go out of the road, and the fuel consumption index is calculated according to the standard of 100 kilometers.

Actually, it doesn't matter, when I drive the manual transmission, such as cornering and going downhill, I take off all the gears and brake wholeheartedly. It's not a big hazard to the car itself, is it? As for the above said:

Difficulty braking. I don't think that whether the sedan is in gear or not does not affect the brakes. It is even said that if the car does not start, it will not affect the brakes.

Brakes should work at all times. There is no such thing as "difficulty".

Neutral coasting is very dangerous, and the current engines are computer-controlled fuel injection, neutral coasting is not fuel-efficient, and neutral coasting is not recommended.

That's right. The main thing is not safe, nothing to the vehicle.

Can drive now? Old schoolmates. Lately, okay?

Braking is difficult, there is no harm.
