Abstract

The   work   aimed   at   solving   the   problem   of   conversion   of   existing   diesel   power   drives   of   oil   and   gas   technological   transport   into   gaseous   fuels,   which   are   a   cheaper   alternative   to   diesel   fuel.   A   method   has   been   proposed   to   increase   the   energy   efficiency   of   alternative   fuels.   The   thermochemical   essence   of   increasing   the   energy   of   the   source   fuel   has   been   developed.   The   choice   of   alternative   alcohol   fuel   as   a   starting   product   for   the   conversion   process,   taking   into   account   its   cost   and   energy   value.   The   calculations   showed   that   the   thermal   effect   from   the   combustion   of   converted   CO   and   H2   exceeds   the   effect   from   the   combustion   of   the   same   amount   of   liquid   methanol.   Compared to other alternative fuels, the cost of methyl alcohol is low, in addition, when using methanol as a fuel for diesel engines, you can significantly reduce emissions of soot particles and nitrogen oxides. This is due to the fact that the combustion of methanol in the diesel cylinder does not form intermediates that promote the formation of acetylene and aromatic hydrocarbons, which lead to the formation of soot. Methanol is a renewable natural resource, ie there is a large raw material base to increase its production and much wider use as an energy source. Using of this alcohol as an alternative biofuel for vehicles is possible as a result of its production in affordable and cheap ways from agricultural and food waste, from gaseous fuel.  Fuel   energy   and   engine   power   were   increased   by   regenerating   the   heat   of   the   exhaust   gases.   Experimental   studies   of   power   and   economic   performance   of   a   diesel   engine,   which   was   converted   to   work   on   the   products   of   methanol   conversion.   Experimental   studies   have   shown   that   the   conversion   of   diesel   engines   to   work   using   methanol   conversion   products   is   justified.   Given   that   the   price   of   methanol   is,   on   average,   10-20%   of   the   cost   of   diesel   fuel,   the   conversion   of   diesel   engines   to   work   using   methanol   conversion   products   is   quite   profitable.
