FIELD: engines and pumps.
SUBSTANCE: invention relates to methods and systems for correcting the engine filling factor of a two-fuel system. Proposed are engine operation method (versions) and engine system for accurate evaluation of engine filling factor in multi-cylinder engine system operating on different types of fuel and different injection systems. Filling factor is corrected based on the share of each fuel in the total fuel injection value, as well as on the basis of injection type for each fuel. Evaluation of filling factor compensates effect of partial pressure and cooling effect of charge of each fuel, as well as of each type of injection.
EFFECT: improved control of actuators, improved performance of the engine and reduced torque disturbances.
