Dynamic Skipping of ICE Cycles - Advanced 1-D Simulation Model

Popis výsledku v původním jazyce

Cylinder deactivation (CDA) is a well-known approach to reduce internal combustion engine displacement during its operation. In serial production, it is utilized in the static form, which keeps a set of cylinder deactivated for the time of the low load mode. An advanced cylinder deactivation can be applied in a dynamic form, in which all or a set of cylinders follows a specific deactivation pattern, which consist of a number of firing and deactivated cycles. Such a deactivation allows to dynamically vary the engine displacement in finer steps even for a small number of cylinders and brings benefits in terms of NVH and uniform thermal and mechanical stresses in the engine. The work focuses on the thermodynamic simulation of such dynamic cylinder deactivation and unveils all benefits and also the obstacles and issues that must be coped with not even in the simulation domain, but also in the real engine control.
