2. By replacing the standard air filter with a zero filter, you will provide the engine with an oxygen-air mixture. An increase in volume increases the degree of compression of the mixture in the cylinder. This increases the force of the explosion and therefore the power of the engine.

3. Installation "Direct flow". Change the exhaust system of the car. Will add a few percent to engine power. The loss of power during exhaust will remain. But installing a dead muffler is not enough. Many types, low-quality materials, and handicraft products do not always give a positive effect.

4. Turbo engine. If you don't have it in your car, the amount of oxygen in the fuel mixture will increase. More gas. High compressive force and explosive force that will hit the pistons and convert into mechanical energy. Namely, this energy turns the wheels of your car and directly depends on the engine power.

5. Chip settings. Increases the amount of fuel supplied to the cylinders. In this case, power will increase by 5-25%, and torque. By 10-15%. Chip tuning will only be useful for engines without a turbine. This is due to the fact that the turbine is already supplying a large amount of fuel to the cylinders. But tuning all car tuning systems will never be superfluous.

6. Replacement of engine parts and related parts. Boring cylinders and replacing pistons will have a noticeable effect, using lightweight crankshaft parts that work more efficiently will increase power levels. Motorists who choose this route are advised to immediately replace the entire engine with a larger engine. As practice shows, such an increase in engine power will cost you less than any manipulation of engine parts.

7. You can also increase engine power by reducing friction. We are talking about friction between the piston and the cylinder walls. Motor oil usually does this, but you can reduce friction with Remetalizer Resurs. The action of Resurs is to create a protective film, restore the surface of the piston walls and, of course, increase engine power by reducing friction. With this approach, engine power increases by 7-7.6%, which is not bad considering the cost of the storage device and the speed of its impact.

As you can see, there are many ways to increase engine power and there are plenty to choose from. Another thing is that any change cannot be local, but will affect all components of the car. For example, increased power requires stronger braking systems. Such work must be entrusted to specialists, and the parts and materials used must have the appropriate capabilities and characteristics.

Among the main parameters of an air pistol. Bullet speed. The higher it is, the greater the shot energy and breakdown power. The benefits of high-velocity weapons include a smoother bullet trajectory and reduced time to target, which is important for shooting at a moving target.

How to Choose a Pneumatic Impact Wrench

Before you go to the store to buy an air impact wrench, you should ask yourself a few important questions, the answers to which will help you make a successful purchase. This tool has many features and applications, so the performance indicators of different models may vary significantly. One specific impact wrench may be successfully used in one type of work, but completely unsuitable for another. What you need to consider when choosing:

Scope of application
. Determine for yourself what types of work the tool will be used for. Do you need a pneumatic wrench for the garage, a compact device for installing ventilation, or a large unit for loosening truck wheels?
Nut dimensions
. The more compact the fastener, the less tightening force it requires. If you have to twist nuts with thread sizes from M6 to M10, a 1/2 square fit is suitable. A 3/4 square impact wrench is suitable for fasteners with M10 – M18 threads. For larger nuts, a 1-inch square will be optimal.
Torque
. Based on the specific type of work, a tool with a suitable torque is selected, which is usually in the range from 300 Nm to 3000 Nm (not taking into account the industry giants). The wheels of a passenger car can break away at 300-400 Nm, Kamaz wheels at 800-1000 Nm, and extremely loaded joints can only be succumbed to a tool with a rating of several thousand.
Tightening regulator
. An important factor that adds versatility to the tool. The adjustment expands the range of fasteners that can be tightened, but on pneumatic impact wrenches it has an error of 10%.
Device weight
. Working for a long time with a heavy tool with vibration can make life quite difficult. If you choose a pneumatic impact wrench for the garage and small household work for a few minutes a day, then a unit with an all-metal body is suitable. For longer-term use, it is better to take a lighter tool, with a body made of composite materials.

What is the purpose of the update?

If the main use of the pistol. When shooting at cans or bottles, the speed of the bullet or bullet is critical. For a weapon, it is much more pleasant and effective to break a bottle into two figures than an “owl”, which barely leaves marks on the glass.

Since airguns can be used for self-defense and hunting small rodents, increasing the force of the shot also increases its effectiveness. Remember that using modern high-velocity weapons may break the law. Let's look at ways to increase the rate of fire for amateur shooting.

Increasing the power of spring guns

New concept for air spring modernization

Spring-piston pneumatics (PPS) are represented by the most reliable and accurate samples designed for sports or amateur use. Unlike such rifles, PP pistols usually have a much lower rate of fire, which is structurally due to the smaller size of the chamber.

There are ways to give the pool of such weapons more energy:

Increasing the volume of the pneumatic chamber.

Any modernization of the piston spring-piston system is associated with exceeding the operating parameters specified by the manufacturer. Power should be increased gradually, avoiding chasing too high speeds, which can negatively affect the performance and durability of the weapon.

Gas bag

Ways to increase the rate of fire in gas-cylinder pneumatics also involve increasing the barrel length and refining the mechanism. The ways to increase power are as follows:

Replacing the “fighting” spring with a more powerful one. We're talking about a spring that actuates the trigger or barrel, which drops into the valve. The disadvantage of this method is a significant increase in the load on the gun trigger (i.e., an increase in thrust);
Drill the chamber with gas (increase the diameter). Depending on the design of the gun, you can get a nice increase in velocity, especially with the early thick wall chambers;
Enlarged holes in the exhaust valve through which carbon dioxide is released. In the classic valve design, gas is removed through three internal holes. Their diameter can be increased to 0.5 mm by drilling. Don't make the holes too big, otherwise the gas will come out very quickly and the bullet will lose a lot of speed if it gets lost;
Using higher mass triggers (or a heavier rack). With increased pressure, the valve will remain open longer, releasing more gas. To increase the weight you will have to go back to the turner;
Increasing the diameter of the flap is positioned behind the needle to pierce the balloon. Don't overextend it, otherwise the needle may fall out and will need to be fixed with "super glue".

The size of the holes should be gradually increased, periodically assembling the gun and checking the resulting contour. If upgrading was planned before purchase, it is better to buy a model without Blowback, which loses most of the gas.

Bellows

In most cases, bellows tubes are recommended by gas equipment installation specialists. This option is the most reliable and more expensive. But taking into account the very long service life (up to 30 years), it costs 60 cm of finished eyeliner.

Bellows (from the English brand name Sylphon) is an elastic single-layer or multi-layer corrugated shell made of iron, non-metallic and composite materials that maintains strength and density under multi-cycle deformations of compression, tension, torsion and their compositions under the influence of internal or external pressure, temperature and mechanical stress . (https://ru.wikipedia.org/wiki/Bellows)

The bellows hose is made of stainless steel, with a PVC coating on top. This ensures that it will last a long time: the average lifespan is 25–30 years. The iron braid provides strong protection from mechanical stress, and the polyvinyl chloride coating provides electrical insulation and resistance to chemicals. Thanks to the corrugated surface, the product simply bends.

The bellows gas hose has the following advantages:

can be connected to any gas equipment: stoves, boilers, etc.;
has connecting dimensions 1/2″, 3/4″, 1″;
has good flexibility;
withstands pressure up to 6 atmospheres;
wide range of operating temperatures: from 50 to 250 degrees (installation outdoors is allowed; nothing will happen to it if it comes into contact with hot surfaces);
able to withstand mechanical loads, brutal environmental influences, and household chemicals;
hoses comply with the requirements of GOST R 52209-2004, GOST12.2.063-81, GOST12.2.003-91;
warranty service life - up to 15 years;
service life – up to 30 years;
is able to ensure system density even under extreme loads, for example, during an earthquake.

The length of the bellows gas hose varies depending on the connection, it can increase in size by 2 times and has the following characteristics (in meters):

from 0.26 to 0.52;
from 0.5 to 1.0;
from 0.75 to 1.5;
from 1.0 to 2.0.

And the Eliteline office hoses have a fixed length (in meters):

Setting higher speeds for inflated guns has a lot in common with the development of CO2 guns. A common method is to judiciously increase the length of the barrel. You can also use the following approaches:

Reducing valve spring stiffness. This increases the time the gas leaves the chamber and increases the rate of fire;
Valve hole (See above);
Increasing the stiffness or length of the main spring, triggering;
Work on the gearbox in models equipped with it. If the gun does not have a pressure regulator in the air chamber that receives gas after the master cylinder, the reducer will need to be removed and adjusted manually.

The price of increasing shot power. This is an accelerated decrease in cylinder pressure. If the goal of the audit is just to increase ball speed, you may want to experiment with keeping the gearbox as open as possible, avoiding over-spin.

Update security measures

Although air pistols are not considered lethal, their bullets have significant penetrating power and can cause serious harm to a person. Even a small increase in bullet speed can significantly increase its traumatic properties. Thus, an increase in speed by 20 m/s with an initial value of 100 m/s increases the shot energy by almost 1.5 times.

When deciding to increase the power of a pistol, pay attention to safety:

A spring that is too strong in the Transnistrian region can lead to deformation of metal parts when placed on the combat platoon and cause premature firing;
The increased speed of the bullet makes it dangerous at long distances. When using a "pumped" pistol, pay special attention to the absence of people in the direction of fire;
Avoid excessive thinning of the discharge chamber walls when drilling. This reduces the overall rigidity of the structure and can lead to gas puncture injuries due to defects.

Of all types of pneumatics, pistols with piston springs are the most modernized. This is facilitated by the small volume of the air chamber and the difficulties encountered when using more powerful springs.

Carbon dioxide pistols have more acceptable acceleration characteristics, and Champion. Pneumatics with pre-inflation. Do not forget about the established limit of 7.5 J, so as not to become a victim of your own creativity or fall into the hands of law enforcement officers.

Most common problems

Over time, the liner can become deformed, which disrupts the water supply process. Why this happens:

Bad (weak) braid.
Bad fasteners.
Constant flow mode: do not replace a stationary pipeline with a faucet hose.
Incorrect connection, for example, without seals and gaskets.
Inappropriate operating conditions, such as temperature violations.
Wear and tear of devices.

Flexible hose

Very popular because it is versatile. Compatible with virtually any plumbing equipment. In addition, models of this type are suitable for supplying water to a tap that is located at a distance from water intake points. Such hoses for mixers are usually equipped with a brass fitting, which is attached to it with a sleeve or a union nut.

The main disadvantage of similar models is instability to torsion. Very strong bends deform them, which leads to leakage. In general, this option has more positive properties:

Elasticity makes it possible to move the connecting device without damaging the plumbing.
Just hide the part in a box, thereby maintaining the integrity of the interior.
Easy to install.
