You will need

• - a new camshaft,
• - Adjustable gear of the camshaft drive.

Serial production envisages the production of budget-priced cars with engines nominal parameters. In this situation, there are always craftsmen who want to refine the engine in order to "squeeze out of it to the maximum", increasing its power and crankshaft speed.

2

One of the best options for forcingmotor is the installation of a new camshaft with modified cams and an adjustable gear of the drive. Due to the displacement of the valve timing, the crankshaft rotation speed and engine power are increased. The filling of the working cylinders with the enriched fuel mixture is much more efficient.

3

Due to the fact that the motor torqueis directly dependent on the amount of fuel consumed, which, when burned, exerts a higher pressure on the bottom of the piston, installing a tuning camshaft in the cylinder head, the problem of increasing the engine speed is solved.

4

But the solution of this question will not be complete inthe plan for boosting the engine, if we confine ourselves to changing the design of the gas distribution mechanism. For a full tuning of the engine, it is necessary to make changes to the suction path, install a direct-flow exhaust system and modernize the crank mechanism. And then tuning the suspension and brakes. As folk wisdom says: "Licha trouble is the beginning!".

The back part consists, in particular, of the buttock muscles, over which it is necessary to work, as above the muscles. The appearance of the fifth point can be corrected with the help of physical exercises and diet.

1. Exercise regularly. Training on 3 or 4 times a week will teach the body to burn calories, which you consume during the day. At least one or two days of training dedicated to the development of the gluteal muscles, and on the remaining days, do cardio exercises or your favorite sport.
2. Do sit-ups in the gym or at home. Stand so that your feet are at shoulder level. While bending your knees, squat and try to reach a position so that the hips are parallel to the floor. The rear should slightly bulge. Keep weight on the heels, and keep your back straight. Do the exercise 15-20 times in 2-3 approaches.
3. Lie on your back, put your hands along the body. Raise your legs up and bend them at your knees at an angle of 90 ° so that the bottom of your feet is perpendicular to the floor. Slowly lower one leg and touch the floor, then return to the starting position. Repeat this exercise, alternating legs, until you get tired. This exercise works on the bottom of the buttocks.
4. Place your feet shoulder-width apart and stay onone leg, keeping balance. Holding both legs straight, pull up your raised leg so that you feel the contraction of the gluteus muscle. Do this 10 times, change your legs and do as many approaches as you can.
5. Continue training, including in themfor example, jogging, or use the simulator on days when you do not do exercises to strengthen the buttocks. At first, you may notice a decrease in the size of the buttocks due to fat burning. Continue to consistently engage, and fat will be replaced by muscle mass and a healthier fat layer, which will appear due to a change in diet.
6. Limit your intake of simple carbohydrates. Glucose, contained in sweets, lemonades and white bread, for example, first gives a rush of energy, but unused sugar is quickly processed into fat. This fat will be deposited in the buttocks, hips and other parts of the body and will not decorate your figure, which you are trying to change.
7. Replace simple carbohydrates with complex, for example,Whole grains and pasta from durum wheat. They are more nutritious and do not turn so quickly into fat as simple carbohydrates, so you have more time to process them in the gym. Complex carbohydrates also supply the muscles with more energy for training.
8. Eat food saturated with protein. Salmon, lean beef, chicken and eggs are excellent examples of useful proteins that can be included in the diet. Proteins help the growth and strengthening of the muscles after they are damaged in training. The consumption of these dishes will help you to reach the desired size and shape of the buttocks.

Adjusting the speed of the collectorelectric motor with a permanent magnet on the stator, make a change in the voltage on the rotor windings. The dependence of the frequency of rotation of such an engine on the voltage is close to linear.

2

Adjusting the engine speed fromelectronic control and feedback (for example, used in a computer fan) perform the same way, but remember that the dependence of the number of revolutions on the voltage will be somewhat less similar to the linear one. Such motors are not allowed to reverse polarity.

3

To change the number of revolutions of the collector motor with independent excitation, maintaining the unchanged voltage on the stator winding, change the voltage on the rotor windings.

4

To adjust the engine speed fromseries excitation, powered by AC power, use a special thyristor regulator. Many electric tools are equipped with them initially. Do not use regulators not designed specifically for such engines.

5

To change the speed of synchronouselectric motor, proportionally change the frequency of its supply voltage. When the frequency decreases, simultaneously lower the voltage so that the current does not rise through the windings of the motor. If the voltage is not reduced, the current may decrease with decreasing frequency due to a decrease in the inductive resistance of the windings. This mode is dangerous for the engine.

6

To reduce the speed of asynchronouselectric motor, use the same method. If this is not possible (for example, if there is no three-phase inverter), just lower the voltage without changing the frequency. If the engine is single-phase, it is convenient to use LATR for this. Do not use thyristor regulators in conjunction with any non-collector motors.

You will need

• - accumulator battery;
• - megaohmmeter;
• - millivoltmeter.

Instructions

1

To verify the correct connection of three-phase windings, it is necessary to determine the beginning and end of each phase. Prepare a millivoltmeter and a megaohmmeter for this.

2

First, using a warning lamp, determinethe belonging of a particular winding lead to a separate phase. Then, to one of the phases, connect a direct current source through the switch. The power supply must be such that a small current flows through the winding of the electric motor (a battery designed for 2V is suitable). In the circuit, turn on the rheostat to reduce the current.

3

Turn on the switch. At the moment of the beginning of the electrical connection, and also when the circuit is opened in the windings of the two remaining phases, an electromotive force is induced. The direction of the electromotive force is determined by the polarity of the ends of the winding of the phase being checked, into which the battery is connected.

4

Pay attention to the direction in whichthe turning on and off of the switch is deflected by the millivoltmeter needle, which must be alternately connected to the output ends of the other two phases. If the "plus" of the battery is connected to the "start" and the "end" to the "end" - "minus", then when the switch is disconnected at the other phases, there will be a "plus" on the initial leads and a "minus" on the final ones. When the circuit is closed, the polarity on the remaining phases will be the reverse one indicated above.

5

If the electroengine has three outputs when winding is connected by type"Triangle" or "star", check the correctness of the connection by connecting the undervoltage to the two terminals. In this case, measure the voltage between the third terminal and other terminals connected to the network using a voltmeter. If the connection is correct, these voltages will be equal to half the voltage applied to the two terminals.

6

Describe the measurements taken at least three times,each time bringing the current to a different pair of pins. If the phase is incorrectly connected, then with two attempts of three voltages between the third terminal and the others, the voltage will be different.

All asynchronous motors can be dividedinto three groups according to the number of rotor revolutions per minute. The first one is 1000 revolutions. In fact, this figure is slightly exaggerated, since the engine is asynchronous. In a minute its rotor makes a little less revolutions (950-980), and for convenience it was decided to round off. In the engines of the second group, the number of rotor applications is 1500 per minute (in practice, 1420-1480). In the third group, the rotor turns around 3000 times per minute (in reality, 2900-2980).

2

To determine which group yourelectric motor, you must first open one of its lids. Find the coil of the winding, which can consist of either one piece or three or four. There should be several such coils in the engine, you will need one of them, which is easiest to consider.

3

The coils are interconnected by the necessarydetails that may prevent them from viewing them, and which in no case can not be detached from each other. Look closely at the chosen one and try to determine its size with respect to the stator ring.

4

This distance need not be determined fromaccuracy to a millimeter, approximate calculations are quite suitable. In the event that the size of the coil covers one second of the stator rings, the rotor speed will be 3000 rpm. If it closes a third of the ring, then this is the engine of the second group, the rotor of which will rotate at a speed of 1500 rpm. If its size is one-fourth in relation to the ring, rotation will occur at a speed of 1000 rpm. It should be remembered that such figures only approximate the real picture of rotation.

The participial turnover is a construction based on the gerundive.

Deerpriests

The gerundive is a special part of speech, formedon the basis of the verb. It denotes the so-called additional action, that is, that which complements the basic action performed by the subject. Identify girws can be found by finding out which question this part of speech answers. In case it is a gerund, it will be the questions "What are you doing?" For the present and "What is done?" - for the past. Most often, the gerund, signifying an additional action, is in the sentence in the immediate vicinity of the verb that it explains. For example, the following sentence is constructed: "He told me about it, laughing". In this case, "laughing" is the gerund, which answers the question "What are you doing?". On a letter, it is usually allocated with commas.

Participial turnover

If the gerundive is a separate word, thena participial turn is a construction formed on the basis of the gerund, supplemented by dependent words. In general, his functions and characteristics are similar to the gerundive: he also answers questions "What are you doing?" And "What is done?" And means an additional action that specifies the way the main action is performed. In terms of meaning, gerundive turnover is an expanded gerund: for example, such a turn can be used in the sentence "He told me about it, laughing loudly and contagiously". In doing so, when using gerundive traffic in Russian, there are a number of rules that should be remembered in order to correctly use this design. The first of these is associated with punctuation when using a verbal participle: on the letter, in most cases, it is allocated with commas. Constructing a verbal participle, it is worth remembering common mistakes in using it, which must be avoided. So, one of them is the situation when the main verb and the verbal participle that complements it are related to different subjects. An example of such a misuse of turnover is the sentence "This story was told to me, loud and contagious laughing". In this case, the main verb in the sentence refers to the narrated story, and the verbal participle is to the narrator: thus, they are not related to the same person or subject, which is a mandatory requirement for using this design.

How useful is "Gamavit" for dogs?

"Gamavit" for dogs is a complex of useful,biologically active components that optimize metabolic processes in the body of the animal. Also, the drug is able to normalize the blood formula and have a general biotonic effect. Often, "Gamavit is simply an indispensable tool for improving the immunity of dogs. "Gamavit" is prescribed in order to increase the viability of offspring and reduce the mortality of puppies. Another useful property of this drug is increasing the resistance of dogs to all sorts of stresses and increased stresses, as well as improving the performance of muscles. "Gamavit" is used to prevent and treat such diseases in dogs as: anemia, hypovitaminosis, poisoning, pregnancy toxicity, pyometra, infectious and invasive diseases. Also, the drug is indispensable in the process of preparing animals for exhibitions and competitions.

Dosage and contraindications

For preventive purposes, "Gamavit" shouldadministered subcutaneously, intramuscularly, intravenously. It can also be given with drinking. In this case, you need to calculate the dose - not more than 0.1 ml per 1 kg of body weight of the dog. If you are going to treat the animal with "Gamavitom", it is recommended to increase the dosage to 0.3-0.5 ml per 1 kg. Exactly the same dose will be optimal in the treatment of rickets and anemia in puppies.Gamavit should be used intramuscularly two or three times a week for a month and a half. In case of severe poisoning, the drug should be injected once intravenously in a five-fold dosage. It is admissible to administer subcutaneously or intraperitoneally. It is known that infectious diseases are usually accompanied by intoxication, dehydration, exhaustion. With such symptoms, "Gamavit" is administered intramuscularly or subcutaneously twice a day for not more than three to five days. The duration of application depends on the severity of the disease. It is also recommended to take this remedy intramuscularly with deworming for the prevention of anemia and the relief of toxemia. This agent for dogs should be used together with antiviral drugs and antibiotics for maximum effectiveness. After the application of "Gamavit", there were no signs of side effects and some complications. This means that the drug can be considered safe for animals - in this case for dogs.
