1. How to distinguish whether the engine is fuel-efficient
Many people think that when choosing a car, the smaller the displacement, the more fuel-efficient it is. If the absolute fuel consumption seems to be reasonable, it is more important in terms of automotive technology. In other words, with the same fuel consumption, the more effective work the car does, the better. We should not only pay attention to the engine's fuel consumption, but also its power, torque and other power parameters. For example, in the special-purpose vehicles such as the Jianghuai Wrecker and CnhtW light wrecker that were recently listed in the company's four emission standards, the engine has been able to output more than 85% of its output at around 2,000 rpm in a 6-speed transmission. The power, around 3,000 rpm power system to achieve more than 90% of the power output. At 5th gear, 2000 rpm is almost the speed of 60-70 km/h, and 3000 rpm is almost the speed of 110-120 km/h. It is not difficult to find that the two power bursts are exactly at the most commonly used time, especially in the use of urban roads. It is found that power output is very practical.
2. The important effect of tire pressure on fuel consumption
If the engine is the heart of the car, then the tire is the car's limbs. "The journey of a thousand miles begins with one foot," and the tire, which is the only part of the car that touches the ground, has a large impact on fuel consumption. If the tire is deflated, the running resistance will increase and the fuel consumption will increase. Conversely, if the tire pressure is properly increased within the specified tire pressure, the fuel consumption will be reduced. According to tests, tire pressure is 2 psi lower than the specified value (pressure unit: pounds per square foot), and fuel consumption will increase by 1%. Therefore, it is best to check the tire pressure once a month. In addition, the use of certain green tires can also reduce fuel consumption by 3% to 8%. As we all know, driving is not like riding a bicycle. The owner can obviously feel that there is insufficient air in the tires. In most cases, he cannot find out that the tire pressure is insufficient. At this time, the engine is already very laborious. If TPR technology is available, it will prevent the engine from being in a "fatigue" state for a long time, so as to achieve the goal of fuel economy and environmental protection.
3. The small factors that affect fuel consumption can not be ignored
Attention was paid to these major aspects of the engine and the tires, so that the work of selecting a fuel-efficient vehicle was half completed. Next, we must pay attention to some details. Choosing a good brake pad not only reduces brake noise, but also saves fuel and protects the environment. Fuel consumption and air resistance on air conditioning and refrigeration will also affect vehicle fuel consumption.
Of course, the problem of fuel consumption also depends on various factors such as driving habits. However, choosing a more fuel-efficient car is a good start.
With these three points in mind, you can rest assured that the car you want is the right fuel for you! Wish you a happy car in my company!

XCMA Chu Sheng teaches you how to choose a special vehicle for low fuel consumption
The question of oil prices is undoubtedly the most concerned topic for car owners. Those who are prepared to buy cars want to buy a fuel-efficient car to avoid excessive use of cars in the future. However, for ordinary consumers, it is not easy to choose a fuel-efficient model among the new cars that are currently emerging. If you choose from several factors that affect the fuel consumption, the problem can be easily solved.
