METHOD OF OPERATION OF TRANSPORT DIESEL ENGINE Russian patent published in 1997 - IPC

FIELD: mechanical engineering; operation of vehicle diesel engines at high altitude conditions. SUBSTANCE: fuel with self-ignition activator addition is delivered into diesel engine cylinders in amount found from equation where q_ad is amount of addition, % of fuel consumption; A = (1,4 ... 2,1) is nondimensional empirical coefficient accounting for influence of altitude, with lower limit of range related to altitudes above sea level from 0 to 200 m, and upper limit, to altitudes from 2500 to 4500 m; q_m is consumption of diesel fuel; H is altitude above seal level, m; n=(2.2-2.5) is degree accounting for influence of altitude above sea level (i.e.P_a and T_a); lower limit of above-indicated range is related to altitudes from 0 to 2000 m, and upper limit, to altitude from 2500 to 4500 m above sea level. . is increase in cetane number of mixture with addition; Э_o is increase in cetane number of mixture with addition of 1% of base addition; Э_x is increase in cetane number of mixture with working addition. EFFECT: optimization of cetane number of mixture and consumption of addition depending on ambient temperature variation, increased reliability of parts forming combustion chamber surfaces. 1 dwg
