Engines operating on the two types of "swig", at the moment, though not widely, but are still being used on production cars. The brightest example is sectility W12 (two sesenna-row "six", put together), which serves as a coupe and convertible Bentley Continental Supersports. Its main feature is the ability to digest as regular gasoline, and its mixture with ethanol. But on the days krakeroy showed an even more advanced DIC bicarbonate 2. 4, which is able to "drink" at the same time diesel fuel, gasoline, and "cocktail" E85. The prototype, which was partially funded by the U.S. Department of energy, tried it in the minivan Town & Country. With this "four" big pachyderma on the highway consumes just 7.6 l (true, why and in what proportion is unknown), and, for example, with similar capacity mediocre V6 4. 0 - 9,4 L. Experimental novelty equipped fiutowski mechanism changes the valve timing MultiAir, multiple injectors per cylinder, cooling system, exhaust gases Yes a pair of fuel tanks, a separate one for gasoline and diesel fuel. When such "omnivorous" motor appears to massive machines of concern, was not reported. Another question is whether it is necessary at all, because with this the complexity of the design, the price will be considerable, and the same effectiveness can boast highly efficient turbodiesel.
