What is the difference between starting in first or second gear? Thank you

Strictly speaking, with the traction of the engine with enough torque, any gear can be started. However, in practice, because the engine torque of the car is matched to the weight and performance of the car, it is impossible to increase it indefinitely, so not all gears can start. Generally speaking, first and second gears are the more common starting gears on trucks.

When the truck is unloaded, the engine is rich and the torque is relatively large, and the second gear with a relatively small transmission ratio can be used, when the vehicle is loaded, because the transmission ratio of the second gear is less than the first gear, the car can not be brought in the load state, so the first gear is used, starting with the maximum torque and the maximum transmission ratio.

In the car, because it has no load capacity (the load of the car is difficult to exceed 1 ton, the suspension structure and chassis structure are determined), so its torque only corresponds to the weight of the body. At this time, if you start in second gear, the torque is very insufficient. In the case of a very good oil-off coordination, there are some models that can also start, but it will be very slow, and the acceleration will be slow, and if you don't pay attention to it, it will die.

There are some vehicles with relatively small power, and the second gear starts directly to die.

In this case, the car should start in first gear. This approach is good for fuel economy, engine, drivetrain. Forcing a second gear start will put the engine under high load at low revs, and there is also the possibility of dead fire, which will have a negative effect on the engine.

Moreover, starting from the second gear, the second-gear transmission gear of the gearbox will also bear the torque load outside the design, and long-term use will also have a negative impact on the transmission command.

To sum up, the so-called fast start speed in second gear is only for trucks. This is not true for passenger cars, especially small passenger cars. Please use first gear for starting operation to protect the car's mechanical structure and save fuel.

The first gear has a large torque, and it is less likely to stall than the second gear.

Have any of the instructors at the driving school taught the second gear start? According to the coach.

There is a clear difference in maneuverability. It's easier to get started in first gear. Even without going through the accelerator, the vehicle can drive in first gear. However, when starting in second gear, the key stares at the vehicle must be refueled. Otherwise, it is easy to stall during start-up.

No need to refuel your fingers. After the clutch is pressed to the bottom, hang up the first gear. When the clutch is semi-linked, the vehicle can drive. Then, step on the clutch and hook up second gear. Release the clutch and press the accelerator to accelerate, otherwise the vehicle engine will shake and stall in severe cases.

When to use the second gear.

When the vehicle is used on muddy roads or started in snow, the starting torque of the vehicle is large in both cases, and the second-gear torque can fully meet the special road conditions. At the same time, there is a clutch-matched throttle at the start of second gear, otherwise the car will stall due to lack of power.

Millions of car purchase subsidies.

For novice drivers, there is a lot of skill in the process of starting the vehicle. So what's the difference between starting in second gear and starting in first gear?

Lead Round Mountain The second gear start is not as easy as the first gear start, and the gear ratio of the first gear is the largest. And since the torque of the first gear is the maximum, many drivers will hook up the first gear when starting to make it easier for the car to start. When starting in second gear, the owner needs to step on the accelerator first to ensure that the speed of the car is increased rapidly, to ensure the torque of the car, and to drive the car to drive normally.

The second gear seems easy, but it requires strong experience, and only the owner is proficient in this driving style to make the vehicle start faster and more steadily.

Starting in first gear is good for both the vehicle's fuel economy and drivetrain. Forced second gear start will cause the engine to work under high load at low rpm, which will have some adverse effects on the engine. Moreover, after a long period of use of the second gear, the second gear transmission gear of the gearbox also bears the torque load outside the design, which has a great impact on the life of the gearbox.

While automatic transmission cars are very popular in today's automotive market, manual transmission cars are favored by some car owners due to their rich driving pleasure, low cost, and high transmission efficiency. Can I manually stop the start in second gear? What are the advantages and disadvantages of starting in second gear?

In fact, I don't want to talk about it. After all, there are fewer and fewer manual transmissions on the market. I've just seen some people who like manual transmissions always talking about this topic, so I'm going to talk briefly about whether a second-gear car is viable and whether there are more pros or cons.

However, not all manual gears have good drivability. Some self-owned brand cars such as Great Wall and Geely always get stuck when switching from first gear to second gear, and sometimes they can't even hang up. As a result, car owners have developed alternative driving strategies.

Starting with a manual gear, they don't start in first gear at all, but go straight to second gear. The original five-speed transmission was driven in four gears, is this type of driving harmful to the vehicle? Essentially, the car can drive at a high speed, depending entirely on the kinetic energy provided by the gasoline-burning engine, and the gearbox acts as a torque amplification; In fact, when the gear ratio of each gear of the transmission is multiplied by the tail gear ratio, the gear ratio is greater than 1, so each gear of the transmission can play a role in torque amplification.

The difference is that the 1st gear engine has the best torque amplification, averaging about 12 times. The answer is obvious. This driving style will significantly reduce the durability of the transmission and increase the fuel consumption of the vehicle.

At the same time, the vehicle's ability to accelerate from the start is reduced, climbing is difficult, and this driving style is not very good for the engine. Conversely, the higher the gear, the lower the amplification of the engine torque by the gearbox, the more difficult it is to overcome the drag process, and the more difficult it is for the car to start and accelerate. The reason is simple.

The acceleration effect of 6000 rpm in the first gear is better than the 6000 rpm in the second gear, because the amplification of engine torque is highest in the first gear; Therefore, whether we start or accelerate, it is usually advisable to finish in a lower gear. The aim is to make it easier to operate and get better results, which will produce the textbook skills of starting, downshifting, and overtaking! The gearbox of the second gear of the gearbox is comparatively smaller as compared to the first gear.

When the vehicle speed is constant, the corresponding engine speed is low, and the engine output torque is small. When the vehicle is started in second gear, there will also be high-frequency shaking or tripping. In order to make the driving feeling of the vehicle smoother, the owner will use the clutch semi-linkage drive when driving, and the clutch semi-linkage time is very long.

If you drive like this for a long time, the transmission clutch is too worn. If you like your car, after 30,000 or 40,000 kilometers, you may need to replace the clutch assembly, and the transmission clutch life of a vehicle from first gear can reach 20 or 30 years.

Yes, only the first gear can start, the second gear is not able to start, and the impact on the engine is relatively large, which is easy to lead to some cross-branch blocking accidents, which seriously affects the life of the car with a smile.

Yes, when the car starts, it can only be used to start in first gear, and the wide rubber second gear start will make the car's gear and speed mismatched, which will have a great impact on the car's engine, and will make the car's gear wear very serious, which will reduce the service life of the car's sail fiber.

Yes, the car will not stall when starting in first gear during the start-up process, and it will not cause serious damage to the car to ensure the normal starting process. Starting in second gear may cause serious damage to the car's gears and increase the wear and tear of car parts.

It's best to start with a shiver loss; If you use the second gear to start, it may cause stalling, and the car starts steadily, and if you use the second gear to start, it may cause an impact on the other performance of the car and shorten the service life of the car.

1. The biggest damage is to hurt the clutch plate. The torque of the second gear is not the maximum, and it needs a large torque to start, otherwise it will stall. Therefore, in order to keep the flame not extinguished, it is necessary to increase the throttle and increase the engine speed in the half-split hail search state.

In the semi-clutch state, the wear of the clutch plate is the most serious, and the throttle is increased, so abnormal wear will occur, and the life of the clutch plate will be greatly reduced.

2. Waste of fuel. Because the throttle is always increased in the semi-clutch state, there is a lot of oil that just idles the engine and does not turn it into forward power. In this way, once or twice, you may not feel that you consume more fuel, because there is a lot of starting from driving, and after adding up, the fuel consumption will be significantly increased for 100 kilometers.

3. It is easy to stall and produce carbon deposits. If the throttle is not increased much at the start, it may cause insufficient power and even stall at the start. If you don't turn off the ignition and barely start, it will cause insufficient combustion due to insufficient power, produce carbon deposits, and even cause cylinder knocking, and the engine will make a clicking noise, causing abnormal wear of the piston and cylinder.

It is not necessary, the second gear can also start, the throttle is enough to not turn off the sail slowly, but it is not good for the car, so it is recommended to start in the first gear.

The manual gearbox is composed of gears and shafts, through different gear combinations to produce variable speed and torque, the power and speed ratio output of different gears are different, the lower the gear, the greater the output power, the higher the speed ratio. Therefore, the car with one gear has the greatest power, which can make the parked vehicle start, and the higher the gear, the less power the car outputs.

Frequent second gear starts can cause damage to the clutch. The high friction heating temperature of the clutch plate is the main culprit of the wear of the clutch plate, and the friction heating temperature of the clutch plate is 60 degrees higher than that of the first gear at the start. In addition, the second gear start brings a heavier load to the engine, and at the same time, the gasoline cannot be fully combusted, which is easy to form carbon deposits, which will cause wear and tear on the engine.

Manual transmission car starts, hang a gear, lift the clutch at the same time to give oil, the clutch is too fast to cause stalling, the throttle is too fierce and easy to chase the tail, more practice can be.
