When many people buy a car, in addition to the appearance, interior, configuration, and durability, what they are most concerned about is the car's fuel consumption performance. After all, this is the main factor in the cost of using the car in the future, so many car owners have tried their best. to reduce fuel consumption.
Oil prices have been adjusted for several times and have risen relatively quickly. More and more people are spending on cars. The topic of fuel saving has attracted more and more attention. I quickly ask experienced drivers for advice on how to save fuel. However, some of the tips that some experienced drivers think are very fuel-saving are not available. It may not work, but it will consume more fuel. Today I will give you a good correction.
NO.1 Coasting in neutral is more fuel-efficient
This is the favorite thing of many experienced drivers. Indeed, a long time ago, when many models did not have electronic injection engines, or on some large diesel vehicles, coasting in neutral could indeed save more fuel; but now we are in the era of electronic injection. , many models do not inject fuel when coasting in gear. If you continue to coast in neutral, the engine will work at idle speed, consuming extra fuel.
No.2 Manual transmission is more fuel-efficient than automatic transmission
In the era when manual transmission was domineering, automatic transmission technology was not as advanced as it is now. Compared with the 4/5AT automatic transmission, the traditional 5/6-speed manual transmission has much higher transmission efficiency; with the continuous advancement of technology, CVT , DSG, 8AT and other gearboxes are constantly emerging, computer logic is constantly upgraded, gear ratio adjustment is getting better and better, and automatic transmission is even more fuel-efficient than manual transmission.
No.3 Upshifting for overtaking
Generally speaking, most students who have just graduated from driving schools think that high gears are faster, so they need to shift up when overtaking. In fact, high gears have less torque and insufficient power output, resulting in increased fuel consumption. Overtaking correctly You should downshift. For automatic transmission, you only need to floor the throttle, and the transmission will automatically downshift to provide sufficient torque.
No.4 Driving at low speed and high gear
Some drivers like to drive in high gears and low speeds. This will increase the burden on the engine, and low speeds will also cause insufficient combustion in the engine and easily cause carbon deposits. Therefore, the most reasonable way to drive is to let the engine The speed is mostly within the economic speed range.
No.5 The smaller the displacement, the lower the fuel consumption
Generally speaking, small-displacement models have lower fuel consumption than large-displacement models, but this is not absolute. The level of fuel consumption is not entirely determined by the engine displacement. The weight of the body, the aerodynamic characteristics of the car, and the engine Various aspects of the technology and gearbox shifting logic will also affect the vehicle's fuel consumption. Small-displacement vehicles have greater advantages when driving at low speeds, while large-displacement vehicles are more efficient when driving at high speeds.
No.6 Opening the windows saves fuel than turning on the air conditioner
In relatively hot weather, many car owners like to drive with windows open for ventilation, thinking that this can save fuel consumption. This is true at low speeds, but once the vehicle speed increases, it is no longer the case. After opening the windows, The wind resistance produced is greater, so it consumes more fuel than turning on the air conditioner. In addition, the current air quality is poor, so it is recommended to turn on the air conditioner!
No.7 Lower the fuel level
The fuel grade represents the anti-knock performance of the oil. The higher the compression ratio, the higher the fuel grade. If the grade is lowered to save money, it will destroy the design program of the original car's computer, causing it to vibrate. , or it may cause carbon deposits or damage the engine.
Summary: After reading so much knowledge, I believe you will have a new understanding of fuel economy. Some traditional things are not applicable in this era of rapid technological development. Master the correct driving skills and perform regular maintenance on your car. In order to achieve the best performance and achieve the purpose of saving fuel.
