ABSTRACT:
An internal combustion engine in which some of the combustion chamber walls are kept at temperatures which are higher than the temperature of the remaining parts of the combustion chamber. The temperature control of the selected portions of the combustion chamber is performed by heat pipes which lie adjacent to thin combustion chamber walls and which transfer heat from these walls to other parts of the engine which are adjacent to coolant channels. The presence of the heat pipe insures a relatively low thermal inertia of the adjacent combustion chamber walls, permitting their rapid heating after cold starting and the presence of the heat pipe prevents excessive temperatures due to the ability to carry away heat from these parts of the combustion chamber at higher temperatures. The temperature-controlled combustion chamber walls may be provided in auxiliary combustion chambers, prechambers or antechambers. Fuel is preferably injected so as to impinge on the temperature-controlled parts of the combustion chamber.
