Recently, the price of gasoline has moved rapidly, so far, the price of No. 92 gasoline has reached 7.82 yuan / L, in the face of ultra-high oil prices, car owners have said that "this car is really unaffordable", since everyone is so concerned about the fuel consumption of the vehicle, so I conducted a professional fuel consumption test work, mainly to assess the "level of car idle fuel consumption", in order to help everyone decide: when driving daily, whether to use the automatic start-stop function!
True level of idle fuel consumption
Since there is no professional fuel consumption test tool, I use the simplest method to measure the fuel consumption of the vehicle, first fill a tank of fuel, then let the car idle for an hour, turn off the air conditioner, and then use the same fuel gun to fill the oil, the amount of gasoline filled into the tank is the fuel consumption of the car idle for one hour. I chose two cars, one is the Chevrolet Cruze, 1.5L engine, the other is the Hyundai ix35, 2.0L engine, the reason for choosing these two models is not to compare who has lower fuel consumption, but to let everyone know that the car's idle fuel consumption is related to the displacement of the engine.
Chevrolet Cruze idle one hour fuel consumption is 1.5L, while ix35 idle one hour fuel consumption is 1.8L, Cruze daily fuel consumption is about 7.2L / 100km, ix35 daily fuel consumption is about 8.5L / 100km, from this calculation, engine idle for one hour, for Cruze to travel 20.8 km, for ix35 to travel 21.2 km, see this data, do not know whether the owners have panic? Usually stuck in traffic for such a long time, inadvertently let yourself consume so much money. For daily family cars, its idle fuel consumption is very low, but if it is replaced by large-displacement Land Rover, Mercedes-Benz and other models, its fuel consumption will be higher, and the fuel consumption of one hour of idle speed is estimated to reach seven or eight liters.
How to reduce the idle fuel consumption of the vehicle?
Car idle will certainly increase the fuel consumption of the vehicle, but we do not have to give too much worry, in order to prevent idle fuel consumption, the current vehicles are equipped with automatic start and stop function, when the vehicle in traffic jams, waiting for red lights, the engine will automatically turn off, in order to prevent the engine idle operation and the increase in fuel consumption of the vehicle This phenomenon. The engine in the shutdown, start the moment, it will produce occasional jitter, this jitter will make the owner feel slightly uncomfortable, but think about the current price of gasoline, everyone can endure? After all, the engine idles for one hour, which can be used for cars to travel 21 kilometers continuously.
In addition, the cost of automatic start and stop this configuration is also very high, generally equipped with automatic start and stop of the vehicle, its battery, starter have been strengthened, the engine ignition coil has become more durable, the most basic automatic start and stop function, its cost price is more than 2000 yuan.
In order to make the automatic start-stop function more intelligent, engineers have specially developed the Autohold function, Autohold and automatic start-stop is simply a perfect match, after the vehicle stops, the automatic start-stop work, the engine turns off, while Autohold will also work, can prevent the vehicle from slipping phenomenon, the vehicle in the parking, do not need to step on the brakes, just need to release the throttle to wait, the left and right feet can get full rest, when the vehicle needs to start, the owner only needs to lightly step on the brake pedal, the engine starts At the same time, Autohold automatically releases, which can not only save the vehicle's idle fuel consumption, but also increase the vehicle's intelligent driving pleasure.
In summary, engine idle speed will indeed greatly increase the fuel consumption of the vehicle, and it is precisely because of this that the owner should make full use of the automatic start-stop function.
