Why sometimes the engine shut off systems does not work?

What is the engine shut off systems?

The engine shut off systems is a system that intelligently controls the engine's flameout and ignition. It is designed to cope with increasingly stringent emission regulations and environmental pollution problems.

When the car is parked for a short time or waiting for a traffic light, the engine shut off systems can automatically "sleep" the engine, that is, stop idling, in order to save fuel and reduce emissions; when the light is green, release the brake pedal, under the action of the engine shut off systems , The engine automatically ignites and starts.

What conditions will cause the engine shut off systems to not work?

1. Does not meet the safety conditions

2. The vehicle has not reached the ideal working condition, and the battery power is too low and the voltage is insufficient, which will cause the engine shut off systems to not work. This is because during the engine shutdown period, the engine cooling fan and the in-car air conditioner need a power source to provide operating power. High or low engine coolant temperature can also cause the engine shut off systems to not work.

3. The vehicle has not reached the state set by the driver. When the air conditioner in the car is turned on in summer, if the engine is turned off, the air conditioner's refrigeration compressor will not work. Once the temperature inside the car differs too much from the set temperature of the air conditioner, the car engine shut off systems will start engine again.

4. Other circumstances. When driving at a low speed, the vehicle speed does not reach 5km/h after starting; in some cases where the vehicle speed is lower than 15km/h with repeated acceleration and deceleration.

The engine shut off systems can help the car save fuel. On this basis, we should fully understand the engine shut off systems and use it properly.
