[18] theoretically applied the Miller cycle into a supercharged Otto engine. Ebrahimi [19,20] conducted thermodynamical analyses for reversible Miller cycle with considerations of engine speed and variable specific heat ratio of working fluid [19] and for irreversible Miller cycle with respect to the variation of relative air-fuel ratio and stroke length [20].
The purpose of this paper is to evaluate the potential of raw materials for biobutanol, its production technologies and suitability of the product to be used as a fuel as well as to conduct exploitation tests on the mixtures of petrol and butanol in the Otto engine determining the emissions of oxides.

Somewhat lost in all the financial and legal publicity that has surrounded Deutz in recent years is an on-going and interesting engine story, from a company that was founded by Nicolaus Otto, that has been manufacturing engines since 1864, (12 years before the invention of the four-cycle Otto engine) and that will sell over 140,000 engines worldwide in 1997, a number not far below the company's record level.
The Otto engine, as it was called, was such a vast improvement that it caught on at once and was the basis for the internal-combustion engines of today.
