In a direct injection diesel engine equipped with a substantially cylindrical cavity combustion chamber bored at the top of the piston, and a multi-hole fuel injection valve provided in the cylinder head and facing the cavity/r combustion chamber, The fuel injection valve is provided eccentrically with respect to the cavity combustion chamber, and for spray with a short spray length, a part where the spray axis reaches the cavity combustion chamber,
A recessed portion is formed to enlarge the reaching length, and a lip is provided above the recessed portion to compensate for the reduction in squish area width on the top surface of the piston due to the provision of the recessed portion. Combustion chamber of a direct injection diesel engine.
