|Basic sketch Flame-Eater engine|
|Flame Eater process on the basis of 4 piston positions|
|1. The piston moves to the left.
This movement is caused by the flywheel effect. The slide valve is stationary in the left position during this movement of the piston, so the hot flame gases are drawn in the cylinder through the flame hole.
|2. The piston is arrived leftmost.
Even before the piston is at the left position (20 to 30 º earlier) the slide has closed the flame hole in the cylinder. The now enclosed flame gases cool-down by the heat dissipation to the relatively cold wall of the cylinder, which is provided externally with cooling fins.
|3. The piston moves to the right.
The slide valve is stationary in the right-hand (closing) position during this movement. Due to the cooling of the flame gases there is a partial vacuum in the cylinder that enables the outside air pressure to drive the piston to the right. In fact this results in the engine power.
|4.De piston is arrived rightmost.
About 40 º before this position the slide valve opens the flame hole in the cylinder again, so that the cooled flame gases are driven to the outside. The flywheel keeps the movement going and the process cycle is thus repeated.
