Zusammenfassung:	A piston for a diesel engine includes a main body having an annular-shaped upper surface about a central axis, and a combustion chamber provided in the main body to be recessed from the upper surface of the main body, wherein fuel injected from an injector is mixed with air in the combustion chamber. The combustion chamber includes a first bowl and a second bowl above the first bowl with a lip interposed between the first bowl and the second bowl, the lip protruding toward the central axis. The second bowl extends in a radial direction from the lip and includes a bowl guide portion that extends in the radial direction from the lip and is inclined at a first acute angle with respect to the central axis.
