Experts of the AvtoVzglyad portal evaluated in practice the possibilities of fresh modifications of compact best portable air pump for car tires equipped with dual-piston air pumps with reduced energy consumption.
As you know, in recent years, the demand for crossovers and light commercial vehicles has been steadily growing in the automotive segment . Sales volumes of these cars even in crisis years remain stable . This situation has reoriented the interest of consumers to more “larger” tires with seating sizes from 16 to 18 inches and, accordingly, indirectly affected the segment of related “wheel” accessories, the main ones being automotive compressors.
Among these devices appeared models with improved performance, in particular, with increased productivity (from 45 l / min and more), which allows to significantly speed up the process of pumping all four tires on the vehicle, including large tires. True, all such compressors (for example, Carmega APF-411, Airline Expert, Berkut R17) are distinguished by one feature: increased power consumption. Judge for yourself: even with the most "economical" model of this class, the maximum current is at least 20 Amps.
With such indicators, connect the compressor to the on-board network through the cigarette lighter is simply unacceptable for security reasons. And this can be done in only one way - by connecting the wires directly to the battery terminals. That is why the power cables of powerful air pumps of the first generation do not have a plug under the cigarette lighter, and instead of it, each wire (plus or minus) is equipped with crocodile clips. Obviously, to connect them to the bridges, you have to open the hood, climb into the engine compartment, and this, you see, is not very convenient, and not comfortable.
By the way, the increased energy consumption of the models noted above is associated with the design of their pump. It is a single piston pneumosupercharger, driven by an electric motor. This scheme is considered classic in the production of many modern portable pneumopumps.
Recently, the market began to appear more economical version of high-performance auto compressors of the second generation. These devices, assembled on the basis of two-piston pneumosuperchargers, differ from their predecessors by lower power consumption. Such units consume a current of up to 14-15 amps, which allows you to connect their on-board network through the standard cigarette lighter socket. This fact, of course, is a more convenient way to use a powerful hiking pump. However, while in our market, such models still need to search. For example, when my colleagues and I from the AvtoParad portal set out to conduct a comparative test of two-piston car compressors connected via a cigarette lighter, we managed to find only three models. One of them is Chinese AK 0377, the rest are Russian brand devices: Airline X5 and "Kakkh K90x2S". The whole trio has declared close (about 50 l / min) performance values.
5 most expensive Soviet and Russian cars
We are all accustomed to the fact that when it comes to very expensive cars, then, as a rule, these are foreign cars. The synonyms “Russian” and “expensive” in relation to machines are rarely used together. We tried to collect the 10 most expensive Soviet and Russian cars, which definitely cost such a lot of money. Marussia F2
SUV Marussia F2 was presented to the public in 2010. It was equipped with a 3.6 liter engine. 340 horsepower, 4-speed automatic transmission, spring suspension and ground clearance of 25 cm. It was not a crossover, not a SUV, but a real serious SUV. It was planned to launch in the series in 2012.
GAZ-13 “The Seagull
The famous "chlenovoz" (because it drove members of the Central Committee of the party), in contrast to other representative cars of the USSR ("Victory" and ZIM), was never sold freely. The Seagull did not even have a fixed market price. She either walked in a “kit” with an official’s chair, or was given out for special services. For example, these cars were given to the writer Sholokhov, the ballerina Ulanova, and the female cosmonaut Tereshkova. Total GAZ-13 cars were produced 3189 units. Today, “Seagulls” in varying degrees of preservation can be easily purchased on the secondary market. Marussia B1
Marussia B1 was the first car of the company Marussia Motors, which was founded in 2007 by Nikolai Fomenko and Efim Ostrovsky. The car had a V6 engine with 420 horsepower and a top speed of more than 250 km / h. To hundreds of "Marusya" accelerated in 3.8 seconds. Be sure to read about how these cars were created , there are a lot of interesting things.
Marussia B2
The second version of the Marussia B2 had the same power unit as in the first version, but it was significantly different in body. It is noteworthy that the two B2 cars presented at the Frankfurt saloon had different bodies: in one of the carbon and in the other of basalt. It is a pity that in the end everything ended so sadly . These were great cars.
Bear
Incredible amphibious all-terrain vehicle with huge wheels and a powerful powertrain. In fact, this is a team development. The platform of the car was taken from the army GAZ-66, the wheels are designed separately with individual parameters, and the engines are borrowed from Nissan. The huge diesel unit under the hood of the Medved consumes more than 30 liters of fuel per hundred. Thanks to its huge wheels with reduced ground pressure, this SUV can go anywhere, even through the quagmire.
