Although automatic cars have swept through today's automotive market, manual cars still have a place and are loved by some Chinese consumers, after all, many car owners have no money in their pockets, eager to pursue the driving experience of the vehicle, and hope to have a vehicle with excellent stability and ultra-low fuel consumption. But now the manual transmission has long been a certain degree of evolution, the common manual transmission vehicles in the automotive market mainly include 5MT and 6MT transmission manual transmission, what is the difference between the two transmissions? How should car owners choose to buy? Don't be confused, and listen to the "car profile" careful analysis!
5-speed transmission (5MT) and 6-speed transmission (6MT), their main difference is the number of gears of the transmission, the more gears, the smaller the gear ratio of the highest gear of the transmission, the correspondingly larger the gear ratio of the lowest gear, and the smaller the difference in gear ratio between each gear. How does the gear ratio difference affect the vehicle? Gear ratio differences mainly affect two aspects of a vehicle: driving sensation and fuel economy.
<h1 class= "pgc-h-arrow-right" > the driving sensation of the vehicle</h1>
The essence of the manual transmission car is to shift gears, especially when driving in the city, almost one hand controls the steering wheel, the other hand is placed on the gear handle, nothing needs to be done, only need to control the transmission gear, so, driving a manual transmission vehicle, must not be lazy, at the right speed to switch to the most appropriate gear.
When the owner switches gears, the smaller the difference in the transmission ratio between the various gears, the lower the engine speed change amplitude, and when changing gears, the driving feeling becomes more smooth and comfortable, so the 6-speed manual transmission has a more comfortable driving feeling. When starting at low speed, due to the relatively high 1-speed transmission ratio of the 6MT transmission, the transmission doubles the torque of the engine more significantly, and the torque transmitted to the wheel is greater, so the 6MT transmission, the starting power performance and responsiveness will be better; when the owner is driving at high speed, the transmission is in the highest 6 gears, and its transmission ratio is relatively low, which also leads to the lower speed of the engine, in this case, the noise vibration of the vehicle engine becomes smaller, and the driving sense of the vehicle becomes more and more comfortable.
<h1 class="pgc-h-arrow-right" > the fuel economy of the vehicle</h1>
The fuel consumption of the vehicle is mainly related to the engine, and the higher the fuel efficiency of the engine, the lower the fuel consumption of the vehicle. Why does the transmission affect the fuel consumption of the engine? According to the engine fuel consumption MAP chart, the fuel consumption of the engine is related to the load and speed of the engine, and only when the load and speed of the engine reach the most suitable state, the fuel economy of the engine can reach the best state, which is determined by the basic characteristics of the engine.
The existence of the transmission is used to distribute the load and speed change of the engine, the number of transmission gears, and the wider the range of transmission control of the engine speed, the more conducive it is to make the engine work in the optimal fuel consumption area. Under the same speed condition, the speed of the engine can be controlled by the transmission by switching gears and changing the transmission ratio, such as the speed of 60km/h, the transmission in 4 gears, the speed of 2000rpm, in 5 gears, the speed of 1700rpm, in 6 gears, the speed of 1500rpm, can meet the needs of different driving conditions of the owner for traction, so that the engine works as much as possible in favorable working conditions.
For 6MT transmission, its biggest advantage is the vehicle high-speed fixed speed driving, in this case, the engine will always be at a lower speed work, such as the vehicle at 120km / h high speed, many 5MT transmission vehicles, its engine speed of 3500rpm, the engine speed is very high, but the vehicle at high speed, its resistance is constant, the higher the engine speed, the worse the fuel economy. The 6MT transmission vehicle, due to the highest-grade 6-speed transmission is relatively small, the corresponding engine speed may be 3000rpm, the speed is low, the number of fuel injections of the engine is less, and the friction power loss is reduced, which will definitely significantly reduce the fuel consumption value of the vehicle.
In summary, the more manual transmission gears, the more conducive to improving the driving smoothness and driving stability of the vehicle, but also conducive to improving the fuel economy of the vehicle, at the same time, the engine noise at high speed is also smaller and lighter.
