Nowadays, many cars have ECO mode, and there are different opinions about ECO mode. Some people think that the ECO model is not fuel-efficient, while others think that it will increase carbon deposits, leaving many car owners at a loss. I think this problem can be explained in the following ways:
Nowadays, more and more models have a driving mode selection function, and the models with the driving mode selection function must have a mode, that is, ECO mode, which is the so-called "energy-saving" mode. For some consumers who don't know much about automobiles and mechanical principles, what exactly is this ECO model?Can it really save electricity?
In fact, the working principle of ECO mode is very simple, not as complicated as everyone thinks, and does not involve any hardware changes. ECO mode and regular mode (which is defined as "comfort mode" on most models) are more just changes to the gearbox shift logic. In ECO mode, the gearbox is more willing than in normal mode.
When upshifting, the transmission will upshift as much as possible to help keep the engine low, and the engine will become less willing to downshift. When you accelerate sharply, the gearbox will become unresponsive and will not downshift. gear, so that the engine speed does not increase too fast, so as to achieve the purpose of saving fuel.
The main principle of the ECO mode is not very complicated. It is mainly to comprehensively judge and analyze the automatic transmission gear, engine speed, vehicle speed, braking, transmission oil temperature and other conditions that have an impact on fuel consumption during vehicle driving. The ECU control unit calculates the optimal amount of fuel supplied to the engine for operation, compared to normal driving modes.
Effectively reduce fuel consumption. To put it simply, it is to control the engine speed in a reasonable gear to reduce unnecessary fuel consumption. On many Japanese and Korean models, car owners will find a green eco button on the dashboard, which is an energy-saving mode. In fact, in addition to Japanese and Korean models.
Some European and American brands such as Ford, Chevrolet, and Buick have also begun to equip this energy-saving mode, but the ECO mode itself is divided into two types: active and passive. Among them, the passive eco does not have a special button, it is a reminder function. When driving, car owners will notice a green ECO reminder sign on the dashboard.
At speeds above 20 km/h, ECO intelligently evaluates current fuel consumption to achieve the best fuel supply. When measuring, the instrument panel displays the word green eco at the same time. If the owner presses the accelerator hard to accelerate, or encounters a hill climb, the word eco will disappear. Why does eco mode save fuel?
This is mainly due to the corresponding delay in the vehicle's accelerator pedal under ECO mode. For example, the accelerator pedal depth in ECO mode is 40%, which is equivalent to 30% of the accelerator pedal depth in normal mode. With this control, when the owner presses the throttle in ECO mode, the engine intakes more slowly and injects more evenly.
Engine fuel efficiency has improved, and vehicles are naturally more fuel-efficient. As for the gearbox, in ECO mode conditions, the gearbox upshifts very aggressively. Under normal circumstances, when the accelerator pedal is pressed below 40%, the engine speed is completed at about 1800 2000rpm, and the engine speed is often below 2500rpm.
When working, according to the engine map map, it can be found that the engine fuel efficiency is higher. In fact, ECO mode only provides the most economical control over engine torque and transmission gears, and does not cause excessive carbon deposits in the engine. We all know that the fuel consumption and power of a vehicle are always contradictory.
If the power of the vehicle is good, the fuel consumption will be higher. On the contrary, if the vehicle is weak, the fuel consumption will be better. This is also the reason why most car owners are afraid to step on the accelerator. After all, the fuel consumption of stepping on the accelerator makes car owners feel distressed. To sum up, turning on ECO in urban congestion and other situations not only has a relatively obvious fuel-saving effect.
In addition, the ECO mode starts more gently, making it easier to control when following the car in urban congestion. If you don't turn on the eco, the throttle will be too sensitive and the start will be too abrupt. But it doesn't matter if you can't drive on the road when the road is good, especially on the highway. This applies to both new and used vehicles.
