BENZINOVODYANOE fuel for «The Cossacks»

«Zaporozhets 968» Engineer Tsono Petkov from the Bulgarian town of Ruse, one of a kind. It works on a mixture of gasoline and water. Water flowing into the cylinders of the engine, improves mikrodetanatsionnye processes during combustion of fuel and reduces the thermal load of parts of the crankshaft that allows you to use lower grades of gasoline without reducing the power of the machine. In addition, in the exhaust gas is reduced content of harmful chemicals, particularly nitric oxide, which is important for environmental protection. Bench testing of a new engine showed that the water supply device and the emulsification may be successfully used in diesel systems.

HYDROGEN. When, why and how?

More and more experts see today in hydrogen only panacea for the effects of a lack of oil. The expert on energy issues, a former adviser to corporations, «Ford», «General Motors» and «Exxon» John Bockris calls the eighties of this century, the era of hydrogen energy.

A liter of hydrogen in 2.5 «vigorously» a liter of gasoline. Convenient to transport it through pipelines. Because of the smaller specific weight it moves through the tubes three times faster than an underground gas. Even at 700 km length of the pipeline transportation of hydrogen becomes more economical power transmission by wire.

In various research centers seeking the most efficient method of producing and storing hydrogen.

According to George. Bockris, the biggest gains will be achieved through a combination of already known and only studied ways. He calls the main ones: the electrolysis of water using electricity nuclear power plants. The electrolytic hydrogen already in 1985 could be cheaper than gasoline; thermochemical decomposition in which hydrogen and oxygen are obtained by heating steam for heating can use waste heat of nuclear power plants; photochemical decomposition of water using solar heat and catalysts; first hydrogen was obtained in this way for more than 10 years ago; gasification of coal under high pressure — beneficial to countries with low-value coal reserves. Moreover, during combustion of treated

Model hydride tank «Mercedes Benz» .tak way coal produces 10 times less harmful impurities.

Provo (Utah) operated a fleet of hydrogen firm «Billings». Hybrid tanks of vehicles (buses and one) filled with powder of iron and titanium. This mixture, acting like a sponge absorbs hydrogen and eliminates the possibility of explosion. Currently the company is converting a hundred cars «Dutson» for hydrogen fuel.

The same firm «Billings» building in Utah a special «hydrogen» in the town of 38 houses heated by this gas. All municipal machinery and equipment of the city will also be hydrogen powered. Hydrogen firm «Billings» — electrolytic, electricity for its production is obtained from solar and wind power. To build the pipeline transportation of hydrogen.

The problem of trying to solve the hydrogen storage accumulation of it in the form of chemical compounds — metal hydrides. They hydrogen is chemically bonded form and is released by heating. The research center of the company «Mercedes-Benz» is used hydride iron and titanium, are now switched to a lighter-granulate mixture of magnesium hydride and nickel. Yet specific capacity (relative to weight) is insufficient. However, the researchers expect in the next ten years to increase the capacity of the hydride battery compared with the current three times. Then a truck with a tank weighing 200 kg will be able to pass on one tank of about 400 km.

Rough calculations show that the transition to hydrogen fuel across the United States (per capita will fall to 10 kW) require cost equal to the cost of the total gross domestic product in 1977

INCREASING turbulence improves combustion

At the heart of the internal combustion engine — carburetor — pay special attention when it comes to the most important characteristics of the engine, such as fuel efficiency and exhaust emissions. Yes, there is almost everything depends on the carburettor, on how well mixed and twisted, the fuel-air mixture.

Engineers of the American firm «Vortak» offered to be installed in the intake manifold of the engine at the outlet of the carburetor perforated hollow conical insert which by properly executed

8-14 helical grooves Number of grooves and inserts itself depends on the type of carburetor. Almost without increasing the resistance to flow, such insertion improves mixing, being both a passive means of creating high turbulence. As a result, fuel consumption is reduced, and the range increases by 8-13%. The carbon monoxide content in the exhaust gases is reduced by 60%, the hydrocarbon compounds — by 40%, but in tests sometimes obmechalos increased content of nitrogen oxides (5% i by all figures).
