Extreme Sports in jeeps outside Moscow

One day we decided to go to the extreme rest in jeeps in the suburbs, where the off-road we got a lot of experience and loads. Led a group organizer and inspirer of many off-road activities that took over his shoulders than a dozen of these races. - When we communicate with you before you go, you were sure that only travel event no extreme does not herald. How it all began and how it happened that I had to break through severe off-road? - We have formed a group of enthusiasts with whom we occasionally drive out to the car prepared to interesting places on the route in advance, this is not the off-ROAD, which we used to see at the competitions, except when dirt around party sees nothing We're going families, with wives, children, friends. Choosing the road with beautiful scenery and a small obstacle course, where visitors can test their strength and the degree of cross-car. Basically this is the route "Moscow-St.Petersburg" and often go on a trip to a warm seasons. But this time, waiting for the summer did not. We decided to go to the city Ostashkov that in the Tver region. There are beautiful and aesthetically pleasing, is worth seeing, and recreation centers, where you can stop. Originally planned as a trip really excursion: Nilova Deserts, the source of the Volga River, Lake Seliger. Excursions were. On one of them could even wash his boots in the center of the Volga. But very soon the members got bored and started trying to jump off the pavement into the woods.

Riding in low visibility

The most dangerous and difficult it becomes Riding in low visibility, when rain, snow, fog and in the transition from dark to daylight and vice versa, the visibility deteriorated, and range view of the road is less than 300 meters. With the help of a driver receives two-thirds of the information needed to assess the situation on the road and the analysis of maneuver required the driver to ensure the safe movement. For this reason, the lack of visibility, bad review can cause a terrible accident. Consider all the more unfavorable in terms of visibility weather conditions for the drive. Riding in the rain is accompanied by a stream of dirty spray from the wheels colliding and passing cars on the windshield of your car. Even a fraction of a second is enough to take away your visibility on the road, so it is especially important that cleaners (they are "caretakers") were of good quality and have not been worn out by long service life. If the "caretakers" have ceased to adhere to the glass and leave behind a "blind" spots, such cleaners require replacement. However, when rain conditions worsen for the ride, not only outside but inside. As soon as it starts to rain and it drops fall on the windshield, the glass surface cools rapidly, and the inner side of the windows machines are formed condensate. In no case does not wipe the misted glass by hand or by the fact that his arm caught, otherwise the consequences will be in the light of headlights and streetlights examine their own tracks, and divorces, which also impairs visibility.

The operating principle of motor tachometer

Everyone who has a car knows that it mounted tachometer. However, not everyone understands the principle of the motor tachometer. Often you can hear from them questions on the similarity of "What does this arrow?". Therefore, in this article we will explain the basic principles of automotive tachometer. Tachometer in the car - a device that is used to determine the number of engine revolutions. Number of revolutions per unit time changes or relative speed. The main function performed by the tachometer, is that it helps you choose the right gear, but it can prolong engine life. In other words, when the tachometer needle reaches the red zone, you should immediately switch to a higher gear. Also, the tachometer is used for adjustment, for both idle and to control the motor in motion. Tachometer works by recording the number of pulses that are received from sensors, analyzing the pause between them, as well as the order they are received. Counting these pulses can be carried out in various ways: in the opposite direction, forward, and also in both. Indicators that were measured, as a rule, are converted to a certain value. They can be minutes, hours, seconds, etc. Tachometer is designed so that the collected values ??can be periodically reset. And the accuracy of the fairly conventional, the error is approximately equal to 400 rpm., Most accurate car tachometers can display data from up to ~ 100 rpm. Tachometers for motor vehicles are of two types: analog and digital. In the scheme of the digital tachometer may include the following elements: circuit reset the processor, LCD panel, the ADC 8 bits.
