Today, drivers are urgently faced with the issue of fuel economy. Therefore, various devices are available for sale to reduce consumption. They differ in the principle of work, cost and other characteristics.
The economizer Fuel Shark is popular. Reviews on the presented technique must be considered before buying. This will allow us to conclude that it is advisable to install this device on your car.
general characteristics
Fuel Shark is an economizer. These are special devices that can reduce fuel consumption. There are many varieties of economizers. They differ in cost, installation method. Among them, the Ful Shark economizer compares favorably. It has an acceptable cost and does not require alteration of car systems.
You can buy the presented economizer model at a price of about 3-3.2 thousand rubles. The device belongs to the mid-price category. However, its installation does not require high costs.
In appearance, “Full Shark” resembles a modulator, which is simply installed in the appropriate socket. It is connected to the cigarette lighter. You do not need to activate the device. Immediately after connecting to the on-board network and starting the engine, the economizer begins its action.
Economizer Features
Reviews about the economizer Fuel Shark are mixed. To make a correct conclusion about the need to install this device in the on-board network, it is necessary to consider the features of its functioning.
The manufacturer claims that using the Ful Shark economizer, the driver can save up to 20% of fuel. At the same time, the user can hope for a number of positive factors that this device provides.
The manufacturer claims that fuel economy is possible due to the release of charge energy only when necessary. When the system needs more energy, its supply increases from the generator. In this case, the motor efficiency increases, and the lubricant consumption decreases. The service life of the catalyst is increased and the wear of the CPG is reduced.
Operating principle
You can find a certain number of customer reviews that Fuel Shark is a hoax. To answer this question, you need to consider the principle of operation of the device.
A number of factors affect the fuel economy of a car. One of them is the correct, harmonious functioning of the generator. The load on the network leads to increased fuel consumption. Almost every owner of the vehicle could notice that when the headlights or other electrical devices are turned on, the load on the motor increases. This is heard during his work.
The economizer has special capacitors. They recharge when the engine is operating in normal mode. If there is a need to provide consumers with a large amount of electricity, capacitors will transfer the accumulated charge to appropriate devices. The load on the generator in this case is significantly reduced. This, in turn, affects the operation of the engine, allowing you to save fuel.
Instructions for use
Fuel Shark must be used correctly. To do this, the manufacturer in the package provides the availability of instructions. The economizer “Full Shark” is designed for the on-board network of almost all modern cars, which has a voltage of 12 V. Trucks, cars, crossovers and minibuses fall into this category.
The economizer has in its circuit 2200 uF capacitors, resistance and LED. The case looks like an FM modulator. It is enough to insert it into the cigarette lighter and start the engine. The blue indicator on the device lights up.
It should be noted that when using the economizer almost never there are difficulties. However, it should be used for a healthy network. Also, all elements of the mechanisms and electronics of the car must be in good condition. Otherwise, the use of the presented device will not give any result.
Benefits
According to reviews, the fuel economizer Fuel Shark has a lot of positive qualities. Their list is provided by the manufacturer. In his opinion, energy saving is not the only advantage of the device. It can be used for domestic and foreign car brands. In this case, the use of the vehicle network is safe. The economizer does not harm any element of the system.
The appliance starts saving fuel immediately. This can be felt by the reaction of the engine, which starts to work stably even when the load on the on-board network increases. If the car is still under warranty, the installation of an economizer will not cause a refusal to provide car service.
It should also be noted that the flammability index of the fuel mixture is getting better. This increases the efficiency of the engine. This is made possible by increasing the efficiency of the fuel combustion process. However, these specifications are provided by the manufacturer. Technologists and users have a definite opinion about the presented device.
The opinion of technologists
Experts have some doubts about the high efficiency of the device. There are various reviews about Fuel Shark. Whether it is a divorce or not, technologists will help. They argue that each device should have its own shortcomings. For obvious reasons, the manufacturer is silent about them.
The fact is that the maximum declared level of fuel economy is 20%. However, not every vehicle is able to demonstrate a similar result. There are many factors that influence fuel consumption. Therefore, when adverse effects on the system occur, the economizer will not be able to provide high efficiency.
For example, such a situation may occur if the lubricant is improperly selected or if it is not timely replaced. In this case, the friction of the moving elements of the motor, transmission can increase. This factor leads to increased gas mileage. In this case, the stable operation of the generator will not be noticed by the user.
Detailed review of engine operation
Considering customer reviews of Fuel Shark, as well as experts in the field of automotive equipment, it should be noted many doubts about the advisability of acquiring an economizer.
“Full Shark” accumulates a certain amount of energy. This indicator is limited by the capacitance of the capacitor. For the operation of the electric network, much more energy is needed than the presented device can accumulate.
There are also doubts about manufacturers' claims to improve fuel combustion. To achieve this result, it would be necessary to develop a more advanced engine design.
In general, “Full Shark” can to some extent affect the consumption of gasoline. However, it is almost impossible to achieve the declared level.
Cost
According to reviews of Fuel Shark, experts and buyers agree that the price of this device is too high. The device does not include any complex or expensive components.
The cost of the capacitor ranges from 15 to 30 rubles. In this case, the diode, which is included in the circuit will also cost about 20 rubles. The resistor is the same as the capacitor. The cost of the plastic case is about 150 rubles. Therefore, making a simple calculation, we can say that the cost of the device is overstated.
This fact also causes distrust among buyers. The economizer of the type presented, according to experts, cannot cost about 3.2 thousand rubles. At the same time, the savings in paying fuel bills are scanty compared to the cost of this device. Therefore, many buyers are convinced that the "Full Shark" is not an effective device.
Positive customer reviews
Considering the reviews about Fuel Shark that customers provide, a large number of negative opinions can be noted. However, there are positive comments.
Drivers note that using the presented device is simple. No need to retool the system. Simply plug the device into the network. The savings, according to reviews, are noticeable. However, the level of gasoline consumption is reduced as much as possible by 10% (according to the most optimistic reviews).
Among the positive qualities, a more stable operation of the electrical system is also noted. However, this device is hardly a panacea for all the adverse factors affecting the operation of the mechanism.
Negative reviews
It should be noted that, according to statistics, 75% of the drivers surveyed leave negative feedback on the presented economizer. They claim that this is a useless thing. The cost of the economizer is quite high. At the same time, its efficiency is almost zero.
Even if the capacitor was not installed at 2.2 and 10 thousand microfarads, this would not be enough to stabilize the system completely. In addition, a number of factors affect the rate of gasoline consumption, which make the acquisition of “Full Shark” inappropriate.
Many buyers claim to feel cheated. They expected fuel savings of around 20% or so. But as a result, they did not receive even 10%. This forces drivers to leave a lot of negative reviews about the item.
Many additional power consumers have capacitors in their design. They work on the principle of an economizer. However, this absolutely does not affect the fuel consumption of the vehicle. A lot of negative reviews from experts and buyers indicate the inappropriateness of acquiring the presented device.
Having considered the features of the Fuel Shark economizer, customer reviews and experts, you can make the right decision about whether to purchase the equipment presented for your car.
