Abstract

Sposób zmiany efektywnego stopnia sprężania silnika spalinowego, polega na tym, że zawór upustowy (ZU) kanału upustowego (KU) tulejki jest odpowiednio zamykany i otwierany przez elektromagnes (EM) na podstawie informacji o aktualnych wskaźnikach pracy silnika takich jak: prędkość obrotowa, kąt obrotu wału korbowego, położenie pedału przyspieszenia, uchylenie przepustnicy, ciśnienie w kolektorze ssącym, ciśnienie w komorze spalania przekazywanych przez sterownik (SS) przy czym otwarcie zaworu upustowego (Zu) podczas suwu sprężania powoduje wydostanie się przez kanał upustowy (KU) powietrza do kanału obejściowego (KO) połączonego z kolektorem dolotowym lub kanałem wylotowym, a przemieszczenie tłoka z położenia dolnego martwego punktu przy otwartym zaworze upustowym (ZU), skutkuje zmniejszeniem czynnej objętości skokowej tłoka w cylindrze, przez co nie powoduje rozpoczęcia suwu sprężania do momentu zamknięcia zaworu upustowego (ZU), który po zamknięciu rozpoczyna prawidłowy proces suwu sprężania silnika. Tulejka świecy zapłonowej do silników spalinowych o zapłonie iskrowym z układem do zmiany efektywnego stopnia sprężania silnika spalinowego charakteryzuje się tym, że wmontowana jest ona w głowicy silnika a wewnątrz posiada osiowo wkręconą świecę zapłonową, ponadto w obudowie tulei świecy zapłonowej poprowadzony jest kanał upustowy (KU) zakończony zaworem upustowym (ZU) wyposażonym w kanał obejściowy (KO) odprowadzający powietrze z przestrzeni roboczej cylindra nad tłokiem silnika. Kanał odprowadzający (KO) może odprowadzać powietrze bądź do kolektora dolotowego lub kolektora wylotowego. Zawór upustowy (ZU) połączony jest z elektromagnesem (EM) oraz sterownikem (SS).The method of changing the effective compression ratio of an internal combustion engine consists in the fact that the relief valve (ZU) of the exhaust channel (KU) of the sleeve is properly closed and opened by the electromagnet (EM) on the basis of information on current engine operating indicators such as: rotational speed, angle of rotation crankshaft, accelerator pedal position, throttle deflection, intake manifold pressure, pressure in the combustion chamber transmitted by the controller (SS) with the opening of the relief valve (Zu) during the compression stroke causing air to escape through the bypass channel (KU) into the bypass channel ( KO) connected to the intake manifold or exhaust duct, and the displacement of the piston from the position of the lower dead center with the bleed valve (ZU) open results in a reduction of the active displacement of the piston in the cylinder, which does not cause the compression stroke to begin until the bleeder valve (ZU) is closed which after closing iu starts the correct engine compression stroke process. The spark plug bushing for spark-ignition internal combustion engines with a system for changing the effective compression ratio of a combustion engine is characterized by the fact that it is mounted in the engine head and inside it has an axially screwed spark plug, in addition, a bleed channel (KU) is located in the spark plug sleeve housing ended with a bleed valve (ZU) equipped with a bypass duct (KO) that discharges air from the cylinder working space above the engine piston. The exhaust duct (KO) can discharge air either to the intake manifold or exhaust manifold. The bleed valve (ZU) is connected to the electromagnet (EM) and the controller (SS).
