In the operation of each car there are moments in which the engine does not receive any load, except for friction forces, but they are present right in it, which means they are part of it. Various lubricants are used to avoid these forces, but they still remain.
This engine operation is called "idling". At this time, the gearbox is not engaged with the input shaft, so the rotation of the crankshaft is not transmitted to the wheels. But do not think that the car must be standing in order for the unit under the hood to idle. Many drivers use the so-called coast to save fuel. For example, a hundred meters left before the turn, and the speed is high, then you can turn on the neutral gear and "roll" by inertia. On the one hand, this is economy, on the other hand, it was possible not to accelerate to such a speed, which, perhaps, took even more gasoline or other fuel that the car engine uses.
Idling plays an important role in operation, because in this mode the engine "lives"a significant portion of the time. This means that before moving away, we turn on the gear, this takes some time. For one inclusion, it is small, but if you count all the gear shifts in a day, a week, a month, a year … The figure is quite impressive.
Actually, an engine's idling can reveal its condition. First of all, if idle floats, it means that some system is not working properly, not as it should. For example, you should think about adjusting the carburetor or checking the electronic control unit. In addition, there may be problems with the ignition, which is quite easy to check. In this case, you just need to make sure that the ignition timing is set correctly, as well as that the gaps are normal. If everything is in order, then you can move on. Idle speed can be disturbed due to a malfunction of the fuel pump, especially high pressure. In this case, it will be pumped, but not enough, which leads to unstable operation with interruptions. You should also make sure that the entire fuel system is sealed, since air entering it is fraught with the same consequences.
Besides the fact that the engine should run "unaided", idling on a warm engine should not exceed 900-1000 rpm, which is an average, some engines have it lower. If idling is observed, but it begins to "float" when it drops to this rate, you should think about the condition of the piston group. First of all, about piston rings. Their wear and tearusually accompanied by increased fuel consumption, as well as a serious drop in power at low revs. In addition, the piston rings wear out in the same way, which means that the oil scraper rings wear out along with the compression rings, which leads to an increase in oil consumption. You can notice this if you periodically check the engine oil level.
The reason for such a check should be blue smoke from the exhaust pipe, which is simply impossible not to notice. In conclusion, idling is a serious job that must be maintained in proper condition, like other car systems.

Many modern cars come with full power accessories from the factory. And one of the available functions is closing and opening the trunk or tailgate. There are no such amenities on old cars, but any motorist can make an electric trunk drive with their own hands. It should be noted that opening is much easier to implement than closing
