Which driving mode saves gas?

Advancement in technology has led to many new changes in the automobile industry. These innovations have led to the re-engineering and design of vehicles with many new features that help improve efficiency and fuel economy. One of these features is the Eco fuel-saving driving mode system.

What is Eco driving mode?

Eco driving mode (Economic Mode - EM) is one of the driving modes equipped on many modern internal combustion engine vehicles. The typical function of Eco mode on cars is to reduce maximum fuel consumption, by controlling the car's 4 basic systems to optimize fuel consumption when moving.

Each car model will have a different Eco mode with its own efficiency. But in general, car manufacturers all agree that Eco mode can improve fuel efficiency by 5 - 10%. In addition, this driving mode also helps reduce environmental pollution because when the car burns less fuel, it will also emit less CO2 emissions.

When should the driver use Eco mode?

Users can use Eco driving mode whenever they want to save fuel. However, because this mode affects the car's performance, drivers should not use it when they need more performance.

Eco driving mode should be used when the car only needs to run at low or medium speed, on short urban roads. If driving across provinces, on long roads, on highways, driving uphill... the driver should not turn on Eco mode because it can be more difficult to control.

Why does Eco mode save gas?

Basically, Eco driving mode helps limit engine and transmission performance thanks to the operating principle of controlling the throttle opening, limiting fuel to the piston.

This mode helps the car to decelerate gradually and limit the injection of too much fuel. If the driver suddenly presses the accelerator, the throttle will not be allowed to expand, avoiding wasting fuel. Eco mode also has a smart feature that allows the driver to accelerate suddenly when needed.

In addition to limiting both engine and transmission performance, Eco mode also fine-tunes air conditioning temperature and other important adjustments, to maximize the vehicle's fuel economy without causing any serious side effects.

Other effects of Eco driving mode include:

Change the throttle response of the vehicle

When Eco mode is selected, the system controls how air is drawn through the throttle valve to save fuel. Engine performance and response are reduced in this mode, but the amount of fuel and air delivered to the engine for combustion is controlled more efficiently.

Change the way your car shifts

Reducing gears makes the engine work harder, consuming more fuel. When Eco mode is on, the ECU will limit downshifting when not really necessary to save fuel.

Change the response of the cruise control system

In cars with cruise control technology, Eco driving mode helps the driver maintain a certain desired speed range for the most efficient fuel use.

Change the air conditioning system on the car

Eco mode can affect the air conditioning performance to save more fuel, by only allowing the air conditioning to operate at 70 - 80% to reduce energy drawn from the engine, instead of at maximum 100% capacity.

It can be said that Eco mode is a set of limits that the manufacturer puts on the car when the user turns on this mode to control and optimize fuel consumption. Thus, when choosing to turn on Eco mode, the user accepts to give up part of the car's power and responsiveness in return for better fuel economy./.
