FIELD: engine building.
SUBSTANCE: combustion-ignition internal combustion engine comprises fuel injection nozzle including tip section exposed to combustion chamber. Nozzle hole is formed in tip section. Besides, it includes a channel forming element forming a flow guiding channel through which fuel is injected from the nozzle opening. Channel forming element includes a section of the channel wall located radially outward from the flow guiding channel. Section of the channel wall includes the first layer which is the section of the base connected to the head of the block of cylinders, and the second layer located radially outside or radially inside from the first layer. Strength of the first layer is higher than the strength of the second layer, and the heat conductivity of the second layer is lower than that of the first layer. Also disclosed is an embodiment of an internal combustion engine with compression ignition.
EFFECT: technical result consists in reducing the temperature of the wall surface of the flow guide channel.
