Repair and car operation

"Keep feet in the warm, and the head in cold", is a popular expression it is known to much, here only adhere to it not all. But physicians urgently recommend to motorists to add good advice to the arsenal and prove the recommendations from the scientific point of view: the head of the driver should have an air temperature on 6–7 ° With below, than at feet. Thereby the thermal comfort at which the driver gets tired less is reached, reacts to change of a surrounding situation better.

To reach such difference of temperatures, in principle, simply, it is enough to establish the conditioner in the car. But the device is expensive and in service is a little whimsical. It is possible поманипулировать glasses of windows, but optimum result to achieve hardly it will be possible. From a small shchelochka of effect any, and in well slightly opened window the wind – here not before difference of temperatures rushes into 6–7 degrees, especially in the winter.

The hatch can become the compromise solution. Exactly thanks to it it is possible to improve a microclimate of your car essentially.

At movement speed of an air stream over the car is rather great. In salon it practically is absent. Respectively, pressure of air in salon is more. But it is necessary to slightly open slightly the hatch as air from within will start to be extended. It is easy for checking, having lit in the "zalyukovanny" car. The smoke from a cigaret a stream will start to come to light, without leaving in salon even a smell. And it should affect a microclimate in the car (and in direct, and figuratively), especially, when in it there are smokers and non-smoking.

Because in car salon with the hatch there is an intensive exchange of air, the heater here too works in the winter more effectively, providing necessary temperature balance.

Except everything mentioned, it is possible to note one more important thing. In case of road accident when the exit from the car through regular doors and windows is complicated or impossible, the hatch can use as an emergency exit.

By the way, noticed? Oddish, by sight linguists, the word "zalyukovanny" entered into a lexicon of motorists quite thoroughly and in anybody any more does not cause bewilderment. As, however, and the hatch in the car roof, being considered first a limit of luxury and accessory only very expensive foreign cars.

What hatches happen?

Conditionally they can be divided into two classes. The first are hatches which are established on the car at manufacturer. They are, as a rule, opaque (though there are exceptions), and in open situation the cover hides under a ceiling covering. Is especially "fancy", consisting of two halves and operating modes providing some: an air fence, an extract, the strengthened extract. A drive at them in most cases either mechanical (manually), or already electrified.

Vrezny hatches belong to the second class. They can be seen on the majority both import, and our cars. They, as a rule, differ from "firm" a transparent cover and one situation at which of the car there is an extract of vnutrisalonny air. (Though there are models which allow to uncover and enjoy completely the open sky over the head. But about it a bit later.)

Than vrezny hatches are good? Conclusive advantage considered that they are unified: to establish this miracle it is possible on any car, from Cadillac to "Zaporozhets". Process of installation does not take a lot of time, naturally, in the presence of skills. At the expert on it leaves hour one and a half-two. The paper template on which the window in a ceiling is cut out enters into a set of the hatch. Psychologically procedure, of course, not from the pleasant – on the new car open a roof, as a can. However, at all on new (namely such "democratism" vrezny hatches differ). But the anticipation of advantages of this simple device should overcome sincere discomfort.

After "skin" is removed, the amplifier of a roof leaves, to tell more precisely, that its part which got to a "window" aperture. To it the frame of the hatch which at all consults with the duties worse further comes to change. Penultimate action is removal of a part of an upholstery of a ceiling. And in summary – the installation of the hatch which is bearing a faint resemblance to assembly of a tambour for embroidery on a fabric. After that it is not recommended to use the hatch within three days: hermetic which apply at installation, should stiffen. (If you had to face "covers" – so call hatches on a slang, – which flow, it occurs because the last requirement is not fulfilled.)

Vrezny hatches happen with what? The choice here, however, as well as disorder of the prices, is great: from the simply, opening in one situation and managing to the owners in $180 together with installation, to "fancy" electric for $700 with the same installation.

But the most optimum option, in our opinion, – installation of the hatch opening discretely, in some fixed provisions, and providing the open corner most suitable in a concrete case. Usually these "covers" have from two to four fixed provisions or a mechanical drive in the form of the rotating handle.

In the majority hatches are executed from the blacked-out glass. But sometimes even such protection does not suffice, especially, when the sun in a zenith. Sun-protection shtorka which enter into a set of some "covers" in this case can help.

There are hatches which not simply provide an air extract from salon, but also are demountable. Such option will suit fans of a safari. In the open hatch it is possible to be put out either with a gun, or with the camera. Only in the car it is necessary to prepare in advance a place for removed "cover". It though is executed from kaleny, and sometimes and the glass reinforced by a microwire, nevertheless demands the accurate address.

And labor-consuming at installation it is considered the most expensive the electric hatch. If it not movable, a principle of its work differs nothing from others, simply process of opening is entrusted an electromotor. By and large – overindulgence, but in the presence of the firm alarm system (providing at statement on protection locking of all glasses) you any more will not forget to close the hatch, it it will make.

The movable hatch provides to owners much more ample opportunities. It is possible to tell, the sum of taken all together. Here only in the shifted condition it bears a faint resemblance to a fairing on the main tractor. Though it can be convenient addition for the car to which often should drag the trailer giving. In the car not hot, and the economy of fuel is available. Pressed the button – and it is ready. However, the price in $700 bites a little. However everyone is free to choose. As a healthy microclimate in the car – not luxury, and need.
