What are the bad habits when driving a manual transmission car, which is easy to hurt the car and co

It often takes a lot of driving skills when driving, and many older drivers are characterized by being able to master a lot of driving skills in many years of driving. For example, if a manual transmission car is in neutral mode, it can save fuel and is very comfortable. Driving is actually not as simple as you might think.

At this point, I'm sure many new car owners are already aware of it. Especially in crowded big cities, if you don't have good driving habits, it will cost you gas. So let's take a look at 4 driving habits that cost fuel and hurt cars.

If you drive a manual transmission car, please get rid of these 4 bad habits, which not only hurt the car but also cost fuel!

First, the owner of the car stops for a short time or waits for a red light. Compared with the idle speed of the car all the time, it must be more fuel-efficient to turn off the engine. However, car owners should also pay attention to the fact that when the engine starts, the fuel consumption is very high, usually about 20% higher than the normal value.

Therefore, if the car owner stops for a short time, such as stopping to buy a bottle of water, some car owners are afraid that it will waste fuel if the car is started all the time, and then turn off the car. However, it takes more fuel to turn off and then restart the engine than it does for a short shutdown. Moreover, the frequent starting of the car can cause wear and tear on the engine.

The inflow and outflow of high currents can also damage the starter and some electronic components.

The second is often high and low speed. This is generally for manual transmission models, when the speed is relatively low, if the speed is not reduced to the appropriate range, accelerate in advance, which not only costs fuel, but also hurts the car. Car owners should know that there is a certain relationship between gear and speed range, if the high speed is low, it will increase the load of the engine, which will accelerate the engine carbon deposit, burning oil and other problems.

The third is to look down at the file. Many novice car owners forget the gear of their car after driving for a period of time, or some novice car owners are not so proficient in the car, which makes the car owner look down because he cannot confirm the gear of the car, this behavior can be said to be very dangerous, in the moment of bowing, it is very likely to lead to accidents.

The fourth is a long-term idle hot car, and the current car is EFI, not an old-fashioned carburetor! As you put on your seatbelt while you light the fire, the car will be warmed up, and then drive at a low speed for a while until the temperature comes up. In the case of smoking a cigarette and waiting for the car to heat up after ignition, it is better not to appear because it will cause carbon deposits in the engine.

To put it simply, let the car heat up in place for half a minute, and then drive at a low speed for a period of time, so that the car's oil can reach the operating temperature, so as to protect the engine and transmission. However, some car owners will not only increase fuel consumption by heating up the car for a long time, but also may cause serious carbon deposition in the engine, which will cause an increase in fuel consumption.

If the right hand is placed on the gear lever for a long time, it will be mechanically worn; If the clutch is not stepped on for a long time, it will accelerate the wear of the clutch; Frequent high-end and low-speed driving will increase the wear and tear of the clutch and transmission.

In the process of using manual transmission, many old drivers have the following bad problems, first, the hand has been on the gear handle, this practice is very dangerous, both hands must always be on the steering wheel. Second, skipping shifts, this behavior may lead to the gearbox gear teething. 3. Neutral sliding, neutral sliding can only use brakes to control the speed, and long downhill slopes may lead to brake failure.

Fourth, you need to look down when changing gears, and it takes at least a few seconds to look down at the gear shift, and this time the car is enough to drive dozens of meters, once there is an accident, the consequences are unimaginable. Fifth, the car does not stop directly on the reverse gear, which will lead to the gearbox teething, and the gearbox will be damaged in serious cases.

1. Hit the throttle with a big foot, which is very common, and will cause more carbon deposits in the engine in the long run. It hurts the car and costs fuel.

2. Shift gears at improper speeds, normally, the speed of shifting gears is 800 rpm in 1st gear, 1200 rpm in 2nd gear, 1200 rpm in 3rd gear, and 1800 rpm for shifting.

When I went to bungee jumping today, when the staff tied the rope to my feet, I was a little scared, so I asked: Look, is your rope a little worn? The staff said:

It's a little worn. Don't worry, it'll be fine. We change it often.

I said, "How often do you change your rope?" The staff said:

It's hard to say, when will it be broken, when will it be replaced! Me: I'll it!

I'm not jumping! The increase in fuel consumption may depend on your road conditions and driving habits, whether it is different, or whether it is due to too much carbon deposit. There are many reasons for this, depending on the car. It is usually the spark plugs, oxygen sensors, intake pressure transmissions, carburetors, computer boards, oxygen sensors that are most likely.

1. The air intake of the air filter is not smooth. Clean or replace the air filter.

Second, the throttle valve is closed and inactive, and the throttle is cleaned.

Third, the tire pressure is insufficient, just like we ride a bicycle, in the case of not much gas, is it very laborious to step on, a reason, the tire pressure of the car is insufficient, will increase the friction between the tire and the ground, and the fuel consumption will naturally increase; There is also a situation where the tire pressure of the four wheels is inconsistent, so that the car sways left and right, and fuel consumption will also increase.

Fourth, the engine oil is not filled according to the specified number. The viscosity of the engine oil is the main indicator of the engine oil, for example, 15w-40 where the "w" represents winter, the more ** the number in front of it, the thinner the viscosity of the engine oil, the better the fluidity, the lower the ambient temperature available for use, and the better the protection ability of the engine during cold start; The number after the "W" is an indicator of the high temperature resistance of the engine oil, and the higher the value, the better the protection performance of the engine oil at high temperatures. Excessive selection of higher viscosity oils increases the drag of engine components, which consumes both power and fuel consumption.

Fifth, the spark plug is used for too long, the energy generated by ignition decreases, the car speed is slow, and the fuel consumption will increase.

6. If you find that the wheel has an abnormal noise during driving or starting, you should check whether the bearing and brake system are faulty in time. If the wheels do not rotate properly, it will affect the speed of the vehicle, which will increase fuel consumption.

7. The water temperature of the engine is too high, and when the water temperature exceeds 95 degrees, the fuel consumption will increase by 30 to 40 percent compared with the normal temperature.

8. Frequent braking, this, you have to predict in advance, try to put the accelerator to slow down, instead of stepping on the brakes all the time.

At present, there are more and more people driving cars, basically driving automatic cars, there are not many people who drive manual transmission cars, the general old drivers will drive manual transmission cars, after all, manual transmission cars can have a good sense of control, but manual transmission cars are sometimes particularly tired, but it may be much better to get used to it, after all, manual transmission cars are relatively safer than automatic transmission cars, and the mechanical properties of manual transmission cars are relatively good, and you can control the speed very well, Then people who drive manual transmission cars also have some bad problems, first of all, put their hands on the gear lever for a long time, most of the friends who drive may have this wrong problem, in fact, this is not right, we should hold the steering wheel with both hands, when the year tremors need to be geared, and then put the hand on the gear lever to hang the gear, which is safer to operate. Secondly, waiting for the traffic light not to hang neutral, we know that the car should be hung in neutral when waiting for the traffic light, which is conducive to reducing the wear and tear of the car engine, but also to bring safety to the driver. Finally, uphill oil separation, this practice believes that many people will appear, although this operation seems to be able to drive well and steadily, in fact, the wear and tear of the clutch is quite serious, we must drive the manual transmission motor vehicle correctly.

First, the hand on the gear lever, although it seems that we put our hands on the gear lever to rest our hands, in fact, the biggest misunderstanding is the safety issue, the car is slightly worn or nothing, we must pay attention to safety, can not relax the vigilance of safety because their hands are relaxed, to drive correctly is the key.

Second, do not hang neutral gear, quietly waiting for the traffic light or parking must hang neutral gear to pull the handbrake, one is to play a certain role in protecting our safety, and the other is to protect the clutch and gearbox wear and tear well, prolong the service life of the car.

Third, the oil is off the match, in fact, we only need to step on the brakes and release the brakes, generally will not slip, don't because of the fear of slipping off the oil to cooperate with the car.

Habitually stepping on the clutch, and often changing gears in the cavity, the use of the brakes of the dry shirt is not so sensitive, especially like to show their own operation, easy to ignore the details.

That is to pull the hand brake and drive. Especially when going downhill, let the engine Sakura braking, and the tomato will hurt the engine a lot. So, don't step on the brakes to go downhill, so that you can protect the brake pads. Don't forget to let go of the brakes before you start.

The answer to these bad habits is that you don't pay attention to the rearview mirror when driving, don't pay attention to your own smile, don't pay attention to your state when driving, don't change gears when you drive a car, and behave very casually when driving.

Automatic transmissions are 50% more convenient than manual transmissions, and manual transmissions are 50% more fun to drive than automatic transmissions. But when it comes to fuel efficiency, automatic transmissions in the traditional sense require more fuel. Now, the two are gradually equalizing.

The automatic transmission is generally a 4AT gearbox, and the shift speed is also high, driving a liter 4AT old Golf, and if you want to maintain a uniform speed of 120 kilometers on the highway, the speed should be over 3500 mph. But now there is only one liter, 6AT car uniform speed of 120 kilometers and only 2500 rpm. This is why in the past it was argued that automatic transmissions were more expensive, because more than 10 years ago, automatic transmissions had fewer gears, higher speeds, and relatively higher fuel consumption.

According to some international automobile theories, now 6AT gearboxes are generally more fuel-efficient than 4AT gearboxes, and with the continuous reduction of the weight of automatic transmissions, many automatic transmissions are more fuel-efficient than the same manual transmission. In order to avoid the national conditions of domestic water army** and public relations of large factories, Gorilla found the automatic transmission and manual transmission of the same car published by a well-known foreign automobile magazine to measure fuel consumption, and the data is relatively fair. Here's a concept you may not be aware of.

Gorilla will popularize it for everyone. Unlike the colloquial name for several oils in China for 100 km, the fuel consumption test in the United States is based on the MPG standard. That is, "How many miles can you run with a gallon?"

The higher the number system, the more fuel-efficient.

In the past, the logic of automatic transmission shifting was vague, and it can also be understood that the transmission is very unintelligent, that is, it cannot go down when downshifting, and cannot go up when upshifting. As a result, it often leads to high-grade low-tow and low-grade high-tow. Although the high-grade low-towing speed is very low, the load is large, so it will definitely not save fuel, although the low-grade high-towing load is small, but the speed is easy to pull too high, so the fuel economy is not ideal; Therefore, the automatic transmission will be equipped with a manual mode for use in critical moments!

Automatic transmissions have fewer gears, but not now. Any automatic transmission has a greater ratio range than a manual transmission. Theoretically, the larger the transmission ratio range, the more fuel saving; As shown in the picture above, the highest gear ratio of the automatic transmission is only, which means that the same running of 120km, 4AT5000 rpm or more 9AT only needs more than 2000 rpm, and the fifth or sixth gear of the manual gear also needs more than 3000 rpm!

For a very simple example, the Fit of the manual transmission is 120km, the engine speed is about 3800 rpm, and the CVT is only 2300 rpm; At 120km, the Suzuki Swift has a manual transmission engine speed of about 3200 rpm!

With the continuous development of torque converters, they began to have a locking function. From the initial % to the current global lock, locking the torque converter means that when the vehicle enters normal driving after completing the starting and acceleration process, the torque converter will lock up and achieve a rigid connectionTherefore, at this time, the efficiency of the torque converter is close to that of the manual transmission, and the comprehensive efficiency has reached about 85%, and the transmission efficiency is not less than 93% of the manual transmission.

This is not necessarily, because the performance of the car is different, and the internal organization is very different, so there will be great differences in the use of the car; We should pay attention to safety when driving, and whether the way of using it is correct, and the correct way of using it will prolong the life of the car.

It's not that the automatic transmission will really be more fuel-efficient than the manual transmission, you must pay attention when driving, don't step on the accelerator, don't step on the brake suddenly, don't step on the accelerator frequently, step on the brake frequently, and drive at a constant speed, so that it will save fuel.
