Which is more fuel intensive, high gear, low speed or low gear, high speed ?

Low-grade high-speed and high-end low-speed are not fuel-efficient, they are fuel-efficient, driving to save fuel, you need to find the most energy-saving feeling of the engine, easy to speed up and the speed is more reasonable to save fuel.

It is easy to produce carbon depositsAt present, most of the cars in the normal driving engine speed to maintain at 2000-3000 rpm per minute, has been able to cover almost all the gears, as for the high-end low speed is still more difficult to achieve, can be simply understood as the car at idle when you hang the gear to 2 or even 3 gear, do you say that the car engine can not be difficult, this is equivalent to the use of gearbox braking, not only can not play the role of fuel saving, but also easy to make the engine produce carbon deposits.

Severe wear of the engine and clutchHigh-grade and low-speed driving is to run in a state where the transmission ratio is not suitable, and it is easy to have engine shake and shouting. At this time, the reciprocating movement of the piston and the rotation of the crankshaft connecting rod are too heavy, resulting in serious wear, resulting in premature damage to the engine, and the clutch is also under a huge load, which makes the clutch plates wear out prematurely.

Hello, the landlord must be more fuel-efficient at low gear and high speed, because the gear is relatively low, the speed is relatively high, and the engine is more fuel-efficient. However, in this case, it is better for the full combustion of the engine and more beneficial to the engine. The high-end low speed is more fuel-efficient, but it is not good for the engine for insufficient engine combustion.

Low gears and high speeds are more fuel-intensive. Because the speed of the gear itself is slow in the low gear, if it is a high rotation that exceeds the load, only the amount of oil can reduce the wear of the gear. Appeals mean that the amount of fuel will increase dramatically, and the speed will not be increased, and it is easy to time, and the throttle wear and tear will also increase the fuel consumption.

Compared with low speed and high speed in low gear, low speed and high speed are more fuel-intensive, and the slow speed wastes excess speed.

High-grade low-rpm is more fuel-efficient than low-grade high-revving speed. In low gear, the gear ratio is small, and the resistance to rotation is also large, so even the accelerator does not turn fast, so it has to travel the same distance. The lower gear is more fuel-intensive.

Low speed. Low gear and high speed. This is more fuel-intensive, because the fuel consumption is the highest every time it is used in this way, and the fuel gauge is the one that consumes the most fuel at this position.

Generally speaking, high-end low-rpm is more fuel-efficient, but this is only a method that can be used after the vehicle reaches a certain speed, and if you use high-end low-rpm in the case of slow death, it will cause damage to the engine.

Hello! High-end, low-speed, and low-speed are not fuel-efficient. However, if you have to choose one of the two to save fuel, high-grade and low-speed are relatively more fuel-efficient than low-grade and high-speed.

Many experienced drivers once said that low-grade and high-speed consumption is 10% more fuel. If the gear is not high and you want to drive at high speed, then you can only compensate for the lawsuit by refueling, so it is quite expensive to drive in this way.

When the engine works in the high-grade and low-speed state, the engine output is weak and the torque is small. If you want to speed up, even if you try to refuel hard, it doesn't have the strength, and as a result, a lot of oil is added, but the machine spins very slowly, so it doesn't save fuel. However, it is more fuel-efficient than low-speed high-speed.

These two are, of course, low-gear and high-speed when there will be some high-end low-speed, which is like running on the highway, which is more fuel-efficient.

Both high-end low-rpm and low-high rpm are fuel-intensive and can cause damage to the engine. The right way to drive is to find that balance point, to ensure that the engine accelerates smoothly while saving fuel is the most correct way to drive.

In these two cases, of course, the low-gear and high-speed speed are fuel-efficient, because in low-gear driving, the engine speed is always high, and the output torque is also very large, so it is particularly fuel-intensive. And when driving at high ends, the speed of the car has already risen, and the inertia pushes the car, so it is very fuel-efficient at this time.

It means that the gear is relatively low, but the speed is particularly fast, and the high-end low speed is that the gear is particularly high, but the speed is particularly slow, and the high-end low speed is more fuel-intensive.

Low gear and high rpm means that the low gear is matched with a very high speed. High-grade low-speed is to use high-grade low-speed driving. Low-gear and high-speed this method is more fuel-efficient and more damaging to the car.

Generally speaking, the engine is more fuel-efficient at low revs. However, if the car is hung on high grade and low speed, it will not necessarily be more fuel-efficient than normal. It's better to drive normally.

The so-called high-end low-speed refers to the acceleration process when driving a manual transmission car at a speed lower than the speed range of the gear. In short, for example, at 50 km/h now, it's best to use third gear. You have to hang five gears.

When downshifting, don't downshift, but rely on the engine to pick up speed slowly. This situation is called high-end low-speed. Can high-end driving save fuel?

Any car has an economic speed. Driving at this speed is the most fuel-efficient. When the speed of the vehicle is lower or higher than this speed, fuel consumption increases.

After reaching a certain speed, fuel consumption increases significantly.

For example, the speed of high-flying shuttle is very low, only 1200 speed. In this state, no vehicle torque is applied, and the engine speed is slightly higher than idling. Normal speeds are preferably controlled at about 1500 to 2000 rpm.

Below this range, the engine is always at low torque. Some veteran drivers also like this question. There is no downgrade in time after braking, but the pace of gear is backward.

Self-priming cars are still better, if the turbine is delayed, because the turbine speed will never increase without steering.

And when the throttle speed is lower, the engine sprays more oil into the cylinder, but there is not enough air in the cylinder to participate in the combustion. A part of this combustible fuel is very prone to the formation of carbon, and the oil is a certainty. It is also acceptable if high-level low-rate carbon formation is unavoidable.

At present, the engine speed of most cars in normal driving is maintained at 200033543000 rpm, which can cover almost all gears. As for high-end and low-speed cars, it is still difficult to achieve. It can be simply understood that when the car is idling, you will shift the gear to 2nd or even 3rd gear.

Do you think a car engine can be effortless? This is equivalent to braking with a gearbox, which not only does not save fuel, but also easily causes carbon deposits in the engine. Both low-speed and high-speed low-speed are not fuel-efficient, and both are fuel-guzzling.

If you want to save fuel while driving, you need to find the most energy-efficient feeling of the engine. It's like riding a variable speed bike, it's easiest to climb in maximum gear, and it's easiest to start on flat ground, but it's not fast. You can ride to the highest speed with the smallest gears, but the start is the hardest.

It's a similar principle for driving. For example, it is definitely easier to start in first gear than in second gear, and it is theoretically more fuel-efficient (except in rainy and snowy weather); Let's assume that at 80 mph, we're running in 5th gear, which could be around 2000 rpm. If you change to 4th gear, the speed will definitely be much higher.

At the same speed, the higher the speed, the greater the fuel consumption.

I think the high speed and low gear are very fuel-efficient. If it is a low speed, the friction will increase, but the power will be reduced, and the fuel consumption will be more serious.

These two modes are not fuel-efficient, and when driving at high speed and low gear, the speed is relatively fast, and then the fuel consumption is relatively high and the noise is relatively large; The speed of low-speed and high-end operation is relatively slow, which will cause a negative burden on the engine and damage the engine later.

Both of these situations are very expensive, and you have to match the gear and speed so that the engine and gearbox don't wear out.

In the case of high-speed driving, the general vehicle is in the highest gear and the speed is relatively low. In general, turbocharged engines rev below 2000 rpm at high speed cruising, and some models even lower than 1500 rpm. It is very fuel-efficient compared to urban areas.

In general, the fuel consumption of Volkswagen turbo models is as low as around 5 liters. Advanced low speed and low high speed have always been considered the easiest operations for manual transmission vehicles to destroy the vehicle, but not really destroy the vehicle.

You can't do this without driving a manual transmission vehicle. First of all, let's talk about the so-called "high-end low-speed" of slow digging? "High speed low speed" can be considered low speed or low engine speed.

For example, your gearbox is in 5th gear, but you have to travel 30 km. At this time, the engine speed should be between 1200-1500, which is called "high speed low speed". When driving in the city, the engine speed is relatively high.

At this point, the vehicle is in low gear. When the vehicle starts and accelerates, the speed is very high, and some have to turn to two or three thousand.

Most models tend to consume up to 10 litres of fuel when driving in urban areas, especially in traffic jams. Why is this happening? This has to do with the gearbox ratio.

For example, the transmission ratios of the AISIN 8AT gearbox are in 1st gear, 2nd gear, 3rd gear, 4th gear, 5th gear, 6th gear, 7th gear, and 8th gear. The gear ratio of the first gear means that the countershaft rotates once, the spindle rotates twice, and so on.

The higher the gear ratio, the greater the output torque, the stronger the acceleration ability, but also the higher the fuel consumption. The lower the gear ratio, the higher the engine speed and the lower the fuel consumption. After completing the fuel consumption, let's talk about the load of the vehicle.

Many people think that the speed of high-speed driving is fast, and the loss of vehicles is relatively large. Conversely, vehicles traveling at high speeds have a relatively small load because, although the speed is higher, the engine speed is lower, the engine is in the high-efficiency range, the combustion is relatively sufficient, and the carbon deposits are less. However, urban areas are different.

Stalls, inefficient engines, high speeds, and under-burning road conditions can increase carbon deposition. As a result, road conditions that stop and walk in urban areas suffer the most from vehicles.

High rpm in low gear. Because the fuel consumption of low gear and high speed is higher, and the wear and tear of the engine side beam is more based on large transportation and leasing, so "low gear and high speed" is more fuel-intensive and destroys the car.

In the process of driving, whether it is high-end low speed or low gear high, the speed is actually very harmful to the car, such as high-end low speed, such a form is easy to form carbon deposits inside the engine, when the carbon deposits accumulate to a certain extent, it will reduce the engine power, increase fuel consumption, and seriously affect the run-in of the engine and clutch. If the forward force of the car is very large, and the engine speed does not reach a certain value, it will cause wear and damage to the gearbox. Therefore, these two methods will be more fuel-intensive in comparison, and the damage to the car is also relatively large, which is not advisable.

What is called high-grade and low-speed.

High-end low-speed is when driving a manual transmission vehicle, the current speed is lower than the acceleration process within the speed range of the gear, such as 50 kilometers per hour, at this time should be hung in three gears, but some owners have to hang five gears, beyond the car's gear, only rely on the engine to speed up, this situation is called high-end low speed. In fact, any car needs to be driven according to the economic speed, and driving at this speed is the most fuel-efficient, if it exceeds this speed or is lower than this speed, fuel consumption will rise. Moreover, the long-term high-end and low-speed will make it difficult for the engine to exert its full power, and even cause damage to the car's power system, so this driving method is not fuel-efficient.

The role of the engine tachometer.

The function of the engine tachometer is mainly to show how many kilorpms the engine is currently running per minute in the engine tachometer, there will be a marked number between 0 and 10 The regional unit is one thousand revolutions per minute, if the pointer points to 4, it means that the engine speed is at 4000 rpm at this time, the higher the engine speed, the greater the output power, so the owner can know the operation of the engine by observing the tachometer, and master the appropriate shift to adjust the throttle, Keep the car in optimal working condition.

Finally, no matter what kind of road conditions, long-term high-end and low-speed, low-speed and high-speed are not good for the engine, don't always want to drive with fuel saving. As long as you do a good job of daily maintenance and have a good driving behavior, the fuel consumption of the car will not be as fast as imagined.

High gear, low speed and low speed are more fuel-efficient and hurt the car more, because the gear is high, but the speed is particularly low, which will have a certain impact on the engine, and the rotation of the engine may be subject to certain friction and resistance, thus causing serious damage to the car.

Low-grade and high-speed waste oil, and car parts will also be damaged. The low-speed speed will consume more fuel, so that the parts of the car will suffer a lot of wear.

The practice of high gear and low rpm may directly harm the car's engine, and it will also directly affect the life of the car, so I think it is very fuel-intensive.
