Is the fuel-saving function of the car true?

Saving fuel is also a good thing in environmental protection. Compared with this fuel economy, I often hear people have opinions about this fuel economy function. What is the actual situation? Then let's discuss it together!

1. ECON mode on the car

His role is also the economic and fuel-saving model that everyone often says. Mainly through intelligent adjustment of throttle opening and automobile electrical conditions, to achieve the purpose of fuel saving! In this mode, the gearbox will shift gears more frequently and the power output will be affected. Some friends will worry about carbon deposition, which is worrying. This mode does not rely on low speed to save fuel. The relative fuel-saving effect will be obvious mainly in the case of complex road conditions, and the difference in long-distance cruising can also be ignored!

2. Automobile engine start-stop technology

Automobile engine start-stop technology is also a temporary stop when the car is running, and it can also automatically shut down the engine. When driving continuously, the system automatically restarts the engine system, mainly aiming at the fuel consumption under the condition of less idle speed! Suitable for stop-and-go urban roads. According to relevant tests, it can bring 10% to 15% fuel saving effect every year. The disadvantage is that there will be delay and vibration under different conditions, and the working condition of automobile electrical appliances will decline. If the road is clear, then automatic start-stop will have no effect!

3. The car cruises at a constant speed

This system can be used to control the car to drive at a constant speed, and the fuel supply is also controlled by computer, which reduces unnecessary speed change and usually saves some fuel! This system is only used on highly closed roads, and once it is complicated, it can't cope. Because of the limitation and fuel consumption caused by speed change, cruise at fixed speed is still difficult to save fuel!
