We must know "ECO" mode, this economic model is considered a friend of mine says that the car is more costly, but also easy to produce coke, in the end it is not the case? I take everyone to see.

What is ECO mode?

ECO (Ecology Conservation Optimization) i.e. a power-saving mode, some models also called "ECON" mode, the main principle is to control the throttle opening degree, fuel supply, transmission shift logic, for a long time at a low vehicle speed fluctuation, traveling at low fuel consumption.

Open more fuel-efficient

ECO mode is turned on, trip computer will automatically adjust. The same accelerator depression depth, the throttle opening degree is smaller, the intake air amount and the fuel injection amount will be reduced accordingly, will naturally much less fuel consumed.

Further transmissions will use a more aggressive upshift logic, holding the engine at a low speed, but also limits the amount of air and cooling air conditioning compressor operation to reduce power consumption. This mode is for nothing foot feeling more friendly owners, under ideal conditions can save 6?10?f the fuel consumption.

Under these conditions no effect ECO

ECO mode operation is simple and significant effect, but no effect under some conditions.

High-speed travel time

ECO mode than in the economic speed (typically 60 to 90 km/h) throttle opening degree is maintained at a constant value, ECO mode substantial loss of fuel efficiency.

Parking idle time

ECO mode is mainly controlled by the computer in the own traveling vehicle, but in a manual mode or an idle stop, ECO equally ineffective.

When high torque demand

The face of climbing, ECU computer to determine priority to ensure sufficient power to drive the vehicle, ECO mode will not work.

Abuse can lead to the ECO

In ECO mode, although there are significant fuel efficiency, but will also bring some engine problems: inadequate combustion, carbon deposition increased.

ECO mode, ECU a more aggressive gearbox upshift logic default. For example, when the majority of vehicle start, 1800rpm or 2100rpm be shifting. After opening the ECO mode, when upshift will 1600rpm, the upshift engine speed will fall. Long-term operation at low rpm district, gave rise to inadequate combustion engine fuel problems over time in the vicinity of the valve carbon deposition, erosion of the spark plug is carbon, can also cause severe lack of engine cylinders.

Summary: ECO mode congested roads in the city have relatively good fuel economy results. But owners should be noted that the use of ECO mode for a period of time, we recommend that owners even Rama at high speed, the engine in a timely manner so that it is also a fun means of protection.
