For ensuring improvement of operating characteristics of ship electric power installations with diesel engines of internal combustion it is offered to use additives hydrogenous synthesis gas, the hydrocarbon fuel produced by catalytic converting directly onboard the vehicle. This process will allow to provide realization of advantages of hydrogen fuel without essential constructive changes of power stations. Synthesis gas which mode of functioning is based on preliminary evaporating and the subsequent oxidation of fractions of hydrocarbons of diesel fuel is offered to make catalytic conversion on the basis of use of generators. As a result, gas containing hydrogen and monoxide carbon is formed. Pilot studies on influence of additives hydrogenous synthesis gas on ecological characteristics of diesel engines were conducted on diesel-generator installations 1Ч 8.2/7.5 and 4ЧН 95/115. Tests were carried out in no-load conditions and nominal rotary speed with electric load of the generator. Synthesis gas was supplied in an intake manifold of the engine. It has been established that use of additives of hydrogenous fuel is expedient only during the operation of power stations in the load modes. In the course of the conducted researches it has been shown that use of hydrogenous synthesis gas additives reduces the content of harmful substances in the exhaust gases (including monoxide carbon, hydrocarbons, oxides of nitrogen and solid black particles), and also reduces temperature of exhaust gases. Optimum sizes of giving hydrogenous synthesis gas in a percentage ratio from the mass of the main fuel are determined.
