Nhược điểm ĐC2K:
Contrary to four-stroke engines, the fresh fuel/air mixture in a classical two-stroke scavenges the cylinder after combustion. This causes about 30% of the fresh mixture to be exhausted as unburned oil mist. Along with the only partial burning of the oil, two-stroke engines generate high emissions and cause severe odour, smoke and noise pollution. (https://doi.org/10.1533/9780857096326.565)

Two-Stroke Cycle CI Engine
The two-stroke cycle engine is sometimes called the Clerk engine. Uniflow scavenging occurs with fresh charge entering the combustion chamber above the piston while the exhaust outflow goes through ports uncovered by the piston at its outermost position.
Hàng 10 ⟶ 12:
With the two-stroke diesel engine, intake and exhaust phases take place during part of the compression and power stroke, respectively, so that a cycle of operation is completed in one crankshaft rotation or two piston strokes. Because there are no separate intake and exhaust strokes, a blower is necessary to pump air into the cylinder to push out exhaust gases and to supply the cylinder with fresh air for combustion.

===Ưu điểm động cơ diesel===
The heavier construction, higher compression ratio, nonthrottled air supply, and greater heat value per pound of diesel fuel, as well as the ability to produce rated horsepower (kW) at a lower speed, develop substantially higher torque curves, return superior fuel economy (better thermal efficiency), and offer “life-to-overhaul” typically three to four times longer than that of a gasoline engine, are major attributes of the diesel engine.<ref name="Brady 2004 pp. 515–528">{{cite book | last=Brady | first=Robert N. | title=Encyclopedia of Energy | chapter=Internal Combustion (Gasoline and Diesel) Engines | publisher=Elsevier | year=2004 | isbn=978-0-12-176480-7 | doi=10.1016/b0-12-176480-x/00089-9 | pages=515–528}}</ref>
