UAZ from Belarus, who rides on the wood
And you say, the economy mode, hybrids, electric vehicles. Here in Brest riding UAZ working with wood! For a better understanding of the flow of the machine is worth quoting Sergei motorist and, one might say, the designer: "Once drove into the woods for mushrooms and found that the finished wood for kindling. What to do? Rake promptly inserted into the bucket cones, I threw them into the pot, and went on. " In short, the UAZ can go "for free" anywhere there is wood, which is what is burning. Problems can arise only in a desert.
From the history of
Sergei always took a great interest in history, especially military. Because the move tells of a time when similar gas generators were on the peak of technology:
"Carbon dioxide has been used even cavemen. It is known fact that in his time lighting around St. Petersburg is provided gas-generating plant. The modern history of this device begins with 1919, when the German-French engineer Georges Imbert, returning from the First World, assembled gas generator on charcoal. It takes two years, and is the inventor of the car, whose motor runs on the same principle, only with the improvement. "
"Camera Imbert reversed type" work so that the pyrolysis is not held in the cylinders (like Ford or Porsche), and in the boiler that was installed behind the cab. Pyrolysis in our case - a burning wood in oxygen with effervescence, which turns the motor pistons (but later on this). So, Imbert reached such heights that the building his company Imbert Generatoren GmbH stood next to the Ford factory in Cologne, as if recalling the competition. In the 30's engineer gas generators were placed on the German trucks, cars of Opel and Mercedes. By the time the matured international conflict spilled as a result of World War II, Imbert figured out how to equip your installation of tanks! And improved armored vehicles and even went really were armed - mostly in "Lad Camp" and parts of the auxiliary police (in a simple way - the policemen).
The technology has spread not only in Germany. In the late 20's - early 40-ies in the USSR also made extensive use of trucks with gas generators. Serially their adjusted to AMO, ZIS-21 (produced more than 15 thousand. Models), Ural ZIS. At that time, the Union is experiencing a shortage of oil, but it was impossible to stop the motorisation. Why not "drown" the machine with wood? During World War II, such vehicles be very useful due to zero cost. There is evidence that it is on gas vehicles broke through the siege of Leningrad.
Mass production of oil began in 50-60s, and as a result the new fuel gradually replaced the scientific developments of the early century. Gas generators removed from the machines and simply sent to scrap. Now we see the opposite trend - the rejection of the internal combustion engine, the use of renewable energy sources. For example, according to media reports, the Swedish owners of cars, riding on the wood, encouraged at the state level subsidies. For skeptics should clarify that the gas generator can be fitted to the trailer frame - in this version it is the most aesthetic.
The private museum, which is based in Brest, it is worth acting ZIS-5. Several fans of automotive history once came up with the dashing idea: why not put on a "grandfather", which was issued in 1933, the gas generator. It should be able to - because in 1939 a similar experiment with 21-th model was successful. Sergei decided to repeat. But almost 90-year-old truck - a rarity, antiques, so the man decided not to alter the entire fuel system is so rare nowadays Soviet automobile industry sample. For samples, development of technology, he took up the transformation of more modern technology - the well-known and relatively simple UAZ. The model was chosen based on the interests of Sergei: trophy, off-road 4 * 4.
I guess most readers only learned about the gas generator assembly process would be given up on this venture arm. The fact that Sergei did not buy ready-made sample or collect it at blueprints. He "figured out" the installation of the formulas from the books of the 30s.
"In the library, the network has found the necessary literature - says the designer. - I had to read a lot. Among the authors there are famous names: Tokarev, Panyutin. But the blueprint for the assembly is nowhere found. There is only a formula. Create a gasifier for him - how to re-make the carburetor. It was necessary to calculate the speed of the blast, gasification, the volume of the desired gas mass balance - for engines provide different amounts of different values. Frankly, until now not memorized the multiplication table, but this thing is still collected. Answers to computation using the formulas steel parts installation dimensions and, in fact, drawing itself. Well, the assembly is made from what was at hand. All took a year. "
How does it work?
Fuel for the gasification plant (and in this case we are talking about monoratore) are small wooden chocks. Moreover, it is not necessary that they are dry and moist wood will burn (up to 60 percent humidity) - this contrast monoratora from conventional gas generator. Behind the rear passenger seat next to Sergei machine are two bags of chocks. He says that one is enough for 100 kilometers. In terms of weight it is obtained that the flow rate is 20 kg of wood per hundred. Of course, constantly tossing firewood in the oven is not necessary. I threw in the beginning - and went.
"This is my fuel nozzle. Always carried with me, "- joking man and demonstrates the ax.
According to his story, "gun" may not be useful - coniferous forest, you can safely go to the cones. In any case, environmental installation is undeniable. Since Sergey - a man of ideas, the environment is not an empty word for him
The fuel is loaded into the tank through the cover at the top of the gasification chamber (see photo - black barrel in the center). During operation, there is a continuous smoke. the lid does not pass - so far away the car does not look like a chimney. Before starting the engine, you need to wait about 5-10 minutes to allow the gas to get done.
"At the bottom of the gasification chamber the wood smolder, - Sergey describes the mechanics of the installation. - Start of combustion - with a match or a flare. All three processes take place in the chamber: the thermal decomposition of the fuel, oxidation, reduction. In combustion with depleted fuel quantity oxygen (pyrolysis) of coal flow and hydrocarbon oxidation reactions: C + O2 = CO2, 2H2 + O2 = 2H2O to produce heat. Then there is a reduction reaction (at the passage through the layer of hot coals) C + CO2 = 2CO C + H2O = CO + H2 Heat consumption. Fuel system facing monoratora almost completely decomposed. Condensate is a separate tube, it can be drained. "
The gas enters the pre-filter (on the photo - inverted cone to the left of the camera), which ends in a jar, which is deposited soot, and then passes through a cooling pipe system under the bottom of Oise. If ignite the gas at this stage, the flame is red.
For photo system is connected to bypass the fine filter
If the "dirty" gas to run the engine and its parts will be covered with bloom quickly to drop their service life. Since more fuel is supplied to the fine filter (pictured - green barrel to the right of the camera). Filter element perform simple sawdust. They need to be changed every 2 thousand. Km. After passing through this filter gas burning with a blue flame.
The purified gas is fed directly into the cylinders 2, 4-liter engine, there flares burns driving the whole assembly, and hence the entire vehicle. The exhaust system is full-time, but it emits carbon dioxide (as the people during exhalation). That is, thee is no toxic carbon monoxide, nitrogen oxides, hydrocarbons, aldehydes and other substances against which environmentalists protrude. For the same reason, the engine oil should be changed only after the 30 th. Km.
In terms of comfort, "wood" UAZ is not particularly pleased with - in principle, like all machines of this model (even those that run on gasoline). After a trip on the clothing remains lightweight fire flavor (not annoying), "stove" running hotter than usual. The interior of the gas supply valve lever corresponds, hiding on the left of the steering wheel.
The UAZ has two fuel tanks for gasoline: the left and right sides of the body (especially in case one of them is shot through). To dispel doubts monoratora performance and show that access to both tanks blocked, Sergey demonstrates the lever in the cabin - it is in the neutral position. If necessary, the tanks can be filled with gasoline - then get a kind of hybrid.
Finally - Safety. In the device adjoin open fire and gas that is alarming. According to Sergei, the risk of fire or explosion is minimal, because the gas is not under a lot of pressure. "The same petrol car is easier to ignite than this machine", - assured the man.
Problems with the official vehicle registration is also not - as seen in the photo, UAZ standing on the account, it is fitted rooms. MOT also passed: a gas generator according to the documents - mounted cargo. It can be removed and the bay a little gasoline, travel the line.
"The most exciting moment was - when I first start the engine, - says the designer-lover. - Frankly, the first attempt failed. Then he sat and puzzled, what's wrong? The network has found several of the same Russian and Ukrainian fans as I am. By the time already a forum has been created where children exchanged the nuances of the gasifiers, ways of solving problems. As you can see, in the end, all I got: UAZ work goes steadily on the moor and the road, on the track accelerates to 70 km / h. I will say more: the system can be hidden in the trailer and installed on any vehicle with an internal combustion engine. This is according to my calculations, it will cost about $ 300 in equivalent. You could say the experiment was a success. But I remind you - it was only a prototype. The main project - ZIS-5 comes from the 30s. Now I'm with the team continue to work on it. We plan to finish by May 9 and roll out both cars on parade: pass on the city streets as a grandfather and grandson. Well, then we are sure to come up with something sort of to the 1000 anniversary of Brest ".
