Basing on the harmonic analysis of the indicator diagram, the author proposes a cycle in which pressure varies in a cosine curve. Due to the fact that the second harmonic also contributes to the mean indicated pressure, the author considered the ideal cycle option as the sum of two harmonics. In contrast to conventional cycles, the proposed cycle provides the smallest possible value of the maximum pressure at a given mean indicated pressure. The material of this paper can be used in development of advanced electronic fuel control systems in high-power marine diesel engines.
