An example to tell you the availability of a car emergency power-up

Today, when the price of oil soars, the temptation to turn on and off the engine is obvious. We need to understand exactly what changes it can bring to our everyday traffic.mobile power plant

 The "engine start-stop power supply" is a set of control engine flameout / combustion system. The center is to control the engine stalling / burning according to the vehicle speed and the parking time during traveling to minimize the fuel consumption and reduce the emission when idling. Waiting in the city traffic lights or traffic jams. After the engine flameout, the power supply can replace the pulley on the engine cooling fans and car air conditioning supply power.

In short, the car emergency start power can make the car in the event of a short stoppage time when the engine "sleep", need to start when you can quickly respond (engine start time of about 400 milliseconds, does not affect the normal acceleration), and automatic manual stop Can be equipped. As for the role of the power supply, of course, the engine is automatically shut down in the waiting time of the car to minimize the fuel spills caused by engine idling.

 Compared with the 50% loading rate in Europe, there are not many cars with engine start-stop technology in China at present. However, this system is equipped with the current has been dropping to the compact class sedan, with the engine start and stop technology Compact class models have just listed the new Roewe 550, a variety of models in the traditional power car models using the engine start and stop technology and equipment, Models are equipped with the system; there are also "Blue Drive" as a selling point of Golf and Sagitar, more quoted at less than 100,000 yuan Imperial EC7, leisure and fitness and the Great Wall C30, during which the lowest quotation Guidance of the Great Wall C30 Kai stop, however 66,500 yuan.

 Of course, the flameout is determined condition, automatic stop stepping on the brakes, stop a few seconds after the flame can be stopped, the manual gear is required to loosen the loose clutch, stop automatically shut down after a few seconds. In addition to this basic limitation, there are many special cases that the engine starts and stops when power is on. Such as traffic jams frequently start and stop, driving speed is too low, the lack of battery power, the car temperature is too high / too low, the brake system to lower the pressure below the critical point and so on.

Speaking of fuel economy, the car emergency start power can save us how much oil it? Belfast car fuel economy company, has specifically for the BMW X3 models made a fuel-efficient test. In the vehicle idle time, about 1 hour fuel consumption of 1 liter (to 1.8 displacement for example, not the same displacement), start at about 3 ~ 5 seconds to start idling gasoline.

 Bel-Air tests show that traffic lights under moderate traffic congestion in the city section, get fuel consumption were:

 10.7 liters / hundred kilometers (turn on and off the engine power)

 12.3 liters / hundred kilometers (turn off engine power)

It can be seen, open the engine power start-stop function can save 1.6 liters of fuel / hundred kilometers. Engine start-stop power function is not only suitable for traffic lights in the city traffic conditions, it is also suitable for stop-and-go traffic congestion. But the two can save a different amount of fuel in the red light or traffic control, long time off the road, the engine starting and stopping power car fuel saving effect is more apparent.
