Swirl-Chamber Engine

an internal combustion engine (usually diesel) in which the mixture of fuel occurs through intensive swirling of the air entering a spherical combustion chamber, which is connected with the engine cylinder by a tangential canal.

The advantages of the swirl-chamber engine are stable flow of the heat process; little sensitivity to the quality of the diesel fuel; and a working process suitable for high-speed, small-circulation diesels. The shortcoming of the swirl-chamber engine is its somewhat increased specific use of fuel, caused by higher heat and hydraulic losses.
