Abstract
Sposób zmiany efektywnego stopnia sprężania silnika spalinowego o spalaniu wewnętrznym charakteryzuje się tym, że w silniku o zapłonie iskrowym z wtryskiem bezpośrednim posiadającym konstrukcyjnie podwyższony stopień sprężania, podstawowy sposób regulacji stopnia napełniania cylindra (CS) świeżym ładunkiem odbywa się poprzez przepustnicę (EP) w kolektorze dolotowym (KD), przy czym przy niskim obciążeniu silnika spalinowego zawór upustowy (ZU) pozostaje zamknięty, wraz ze zwiększonym zapotrzebowaniem na moc silnika i wzrostem obciążenia momentem obrotowym efektywny stopień sprężania w cylindrze (CS) jest regulowany za pomocą zaworu upustowego (ZU). Ponadto sposób zmiany efektywnego stopnia sprężania silnika spalinowego o spalaniu wewnętrznym charakteryzuje się tym, że w silniku o zapłonie samoczynnym, posiadającym konstrukcyjnie podwyższony stopień sprężania podstawowy sposób regulacji stopnia napełniania cylindra silnika (CS) świeżym ładunkiem realizowany jest przez układ zasilania silnika, a wraz ze zmiennym zapotrzebowaniem na moc silnika oraz jego obciążeniem momentem obrotowym jest realizowany przez zawór upustowy (ZU), zmieniana jest dawka paliwa, a wartość ostateczna efektywnego stopnia sprężania w cylindrze (CS) jest regulowana za pomocą zaworu upustowego (ZU). Układ do zmiany efektywnego stopnia sprężania silnika spalinowego o spalaniu wewnętrznym charakteryzuje się tym, że silnik spalinowy o spalaniu wewnętrznym połączony jest ze sterownikiem (SS), a ten z elektromagnesem zaworu upustowego (EZ), umieszczonego w głowicy silnika (GS), ponadto układ wyposażony jest w kanał obejściowy (KC).The method of changing the effective compression ratio of an internal combustion engine is characterized by the fact that in a spark-ignition engine with direct injection having a structurally increased compression ratio, the basic way of adjusting the degree of cylinder filling (CS) with fresh load is via the throttle (EP) in the intake manifold (KD), with the relief valve (ZU) remaining closed at low load on the combustion engine, together with the increased demand for engine power and the increase in torque load, the effective compression ratio in the cylinder (CS) is controlled by the relief valve (ZU). In addition, the method of changing the effective compression ratio of an internal combustion engine is characterized by the fact that in a compression-ignition engine having a structurally increased compression ratio, the basic method of adjusting the degree of filling the engine cylinder (CS) with fresh load is implemented by the engine's power supply system, along with a variable the demand for engine power and its torque load is realized by the relief valve (ZU), the fuel dose is changed, and the final value of the effective compression ratio in the cylinder (CS) is regulated by the relief valve (ZU). The system for changing the effective compression ratio of an internal combustion engine is characterized by the fact that the internal combustion engine is connected to the controller (SS), and the one with the electromagnet of the relief valve (EZ), located in the engine head (GS), in addition, the system is in bypass channel (KC).
