The optimalisation of choosing the composition of fuel-water emulsion applied for feeding marine combustion engines

Delivery of water to cylinders is one of the basic ways of limitation of nitrogen oxides concentration in exhausts gases from the diesel engine and is justified in many published results of researches. In effect of engine’s supply by fuel-water emulsion, simultaneously with decrease of nitrogen oxides, the changes of concentration of hydrocarbons, carbon oxides, solid particles, and changes of basic engine’s working coefficients determining its performance and load of crank and cylinder-piston set. In article, the results of researches of water delivery, in form of fuel-water emulsion to cylinders on changes of exhausts blackening; so on the changes in emission of toxic compounds in exhausts were introduced. In addition, the problem of choosing composition of fuel-water emulsion and way of its preparation were taken into consideration.
