Replacing a buld in a car headlight.
First, open the hood of the car. Replacement of lamps can be made, both with removal of a headlight, and without. The headlight itself is easily removed: you need to loosen the mounting bolts and remove the headlight from the car body.Then disconnect the power connector at the rear of the headlight. The lamp itself is protected from moisture and dirt with a special cover. It needs to be removed by turning it counterclockwise. Sometimes the lid is difficult to turn away. In this case, it can be easily pry with a screwdriver.
The most difficult thing: you need to unfasten the metal fastener that holds the lamp in the opening of the headlight. She's tough enough. You need to press the end of the fastener and move it up. After that, carefully remove the lamp from the lamp base. We take out the spoiled lamp.The lamp carefully, trying not to touch the glass bulb with your fingers, insert into the base, and then into the hole in the headlight. After that, snap the clasp, aligning it with the notch on the lamp. Install the lamp cover, turning it clockwise, attach the power connector.

Electrical installations
An electrical installation is a group of electrical equipment that is interconnected and located on the same territory or area. Electrical installation can rightly be considered all sorts of equipment and tools, lines and machines with which to perform these types of operations:Transformation;Transformation;Distribution;Conversion, etc.
With the participation of all sorts of electrical equipment and tools is the conversion of one type of electrical energy to another. Their operation is impossible without the participation of electrical energy, which is supplied as a result of the switching equipment.
With the help of the picture,match the numbers with the names of the instruments and tell what they are used for.
1. Cylinder key.This device consists of a long metal pipe with a head fixed to the end with 6 or 12 faces. It is used to Unscrew and tighten fasteners when replacing wheels.
2. Сandle key. This tool is used when replacing spark plugs of gasoline engines. The most convenient are the models with a hinge joint of the handle, as it is possible to work at an angle.
3. Chain wrench. Using the handle creates the force required to Unscrew. In the field of auto repair chain wrench is used to remove the oil filter and other cylindrical parts
3.Filling the tank with petrol
1.Open the hatch of the gas tank and insert the gun, or trust it to the tanker. After that, as usual, go to the cashier.

2.You tell the cashier: column number, brand of fuel and "full tank" or "to full". The process has gone, the pump has turned on and the gasoline is pouring into your car's tank look into the tank hole and wait for the moment to turn off and take out the gun. Automation will do everything for you. Car refills are equipped with such pistols, which are automatically turned off when filling the tank.
3.If there is no tanker at the gas station, then after the announcement to the cashier of the column number and the fuel brand, you need to walk to the car and see when the gun turns off, hang it in place, close the fuel tank cover and go to the cashier to pay for fuel.
4.Payment can be made according to two schemes. In the first case, you tell the cashier "to full" and after refueling, pay for the amount of gasoline filled. In another case, you may be asked to pay a deliberately larger amount of fuel, for example: your tank holds 46 liters, and you pay 50. After that, the cashier looks at how many liters of fuel fit into your tank, and returns the change for the unshielded liters.
5.At the gas station you are always ready to prompt, help, direct. Contact your assistant or cashier, and you will explain everything on the spot.

Roads
Road — equipped or adapted and used for the movement of vehicles strip of land or the surface of an artificial structure. The road includes one or more carriageways, as well as tram tracks, sidewalks, curbs and dividing strips, if any. which have different speed limits
.A highway is a road for high-speed traffic of cars, which does not have one-level intersections with other roads, railway or tram tracks, pedestrian or Bicycle paths. Designed for high-speed traffic, roadways for each direction of traffic are separated by a barrier or other construction and technical way and have at least two lanes for traffic in each direction, and often a wide curb for stopping cars in unforeseen cases.
In-line engine
Built-in motors, consisting of a package of iron stator with winding, squirrel-cage rotor and fan, do not have a frame, shields, bearings and shaft, they are the most perfect form of organic connection of the engine with the machine. The built-in motor is assembled on the machine. On the shaft of the machine skewer rotor and fan stator is also used to reinforce in the accurately machined bore of the machine bed and after planting zastupovat. It is established that the use of built-in engines achieves the highest compactness of the installation. The use of built-in motors is particularly convenient and advisable when connecting the motor rotor to the drive mechanism of the machine without intermediate gears.

Checking car tyre pressure
1.It is necessary to check the tire pressure before the trip, when the tires are "cold".
2.To check the tire pressure, it is necessary to put the machine on a flat surface.
3.Next, Unscrew the protective cap of the nipple, if any, and connect the pressure gauge to measure the tire pressure. The connection must be tight, so that the air is not "poisoned" on the side, otherwise the result will not be accurate.
4.Make 2-3 measurements, and then draw a conclusion about the state of pressure in the wheel. Be careful not to confuse the units: bar, kPa, kg / cm2 and psi, they are all different from each other so make sure you have 2.2 kg/cm2, not 2.2 psi , for example.
5.If the pressure is lower than necessary, pump up using a pump or compressor, if higher - bleed by pressing the valve nipple.
6.After again we check the pressure and if it is correct — tighten the cap and go to the second wheel.To avoid confusion with the measurement, use the following table of pressure units, it will help you to know what is equal to a particular value.

Highway (FR. chaussee) or highway - a road with an artificial surface, most often-solid, necessarily with a device based on the roadway on top of the ground base, and with ditches for water flow along the roadsides.

V-engine
.
V- shaped engine-a conventional internal combustion engine (ice), the cylinders of which are structurally arranged against each other at a certain angle. Like any other motor, it largely determines the design of the car.
Design features
Structurally, the v-shaped engine is much more complicated than a standard in-line motor. After all, they are equipped with two cylinder heads (cylinder head) and have more complex mechanisms of gas distribution (timing) and fuel injection.
Of great importance in the design of v-shaped engines plays the angle of the cylinders relative to each other. In the process of evolution created different designs in which the angles of the cylinders varied from 1 to 180 degrees.
3. Checking the oil level.
1.Extrusion of lubricant through the channel for installation of the probe and the crankcase drainage system, as well as its ingress into the intake manifold, if the engine provides for the connection of the breather with the power system
2.Difficult to start the engine in winter after a long downtime. Any grease thickens in winter. And if the engine oil reaches the crankshaft-to carry out the rotation of the engine in the thickened lubrication of the starter becomes problematic, and sometimes impossible.
3.The extrusion of the seals. This problem occurs when a combination of factors: exceeding the amount of grease in excess of the allowable rate and blocked crankcase ventilation system. The internal pressure pushes the seal.

Feeder and rural road
Feeder (persistent. feeder) - English fishing tackle bottom, as well as a way to catch fish with this tackle. The peculiarity of this method of fishing involves the use of rods with quivertips (flexible tips), which are the bite alarms.
What ridicule began after his statement that on rural roads it is necessary to go only on an oncoming lane because on it there are less holes! The bus, rocking on a bumpy rural road, drives up to the suburban village. Boots sister the necromancer was not designed to wander through country roads and wander through the mire that stopped the earth after rain.
