Optimization of operating modes of the engine cylinder deactivation mechanism
Abstract
When engine cylinders are switched off at partial loads, the engine fuel consumption is significantly reduced, however, there are a large number of unresolved issues that prevent the creation of such an engine. The paper solves the problem of optimizing the operating mode of the cylinder shutdown mechanism in an engine with a crank-and-rocker mechanism for converting piston motion when the hydraulic drive of the mechanism is fed from the engine lubrication system. To ensure controllability of the cylinder shutdown process, the dependences of the angular velocity of the piston rod rotation on the engine speed mode are obtained using optimization and simulation methods. The obtained data made it possible to minimize dynamic loads in the cylinder shutdown mechanism under rational process control conditions. The results are based on a numerical experiment performed in accordance with optimization algorithms and can be used in the cylinder shutdown control system.
