FIGURE 32.
THE TWO STROKE DIESEL CYCLE.
(2) Compression.
As the piston moves toward top dead center, it covers the
intake ports. The exhaust valve closes at this point sealing the upper cylinder.
As the piston continues upward, the air in the cylinder is tightly compressed. As
in the four stroke cycle diesel, a tremendous amount of heat is generated by the
compression.
