DIRECT FUEL-INJECTION ENGINE

In a cross section in which squish flow from an outer peripheral part of a piston (13) toward a cavity (25) is large due to a width (W2) of a squish area (SA) being large and a squish clearance (C2) being small, a collision angle (±2) at which a fuel injection axis (Li2) collides with the cavity (25...

Beschreibung
Zusammenfassung:	In a cross section in which squish flow from an outer peripheral part of a piston (13) toward a cavity (25) is large due to a width (W2) of a squish area (SA) being large and a squish clearance (C2) being small, a collision angle (±2) at which a fuel injection axis (Li2) collides with the cavity (25) is made large, whereas in a cross section in which squish flow is small due to the width of the squish area (SA) being small and the squish clearance being large, the collision angle at which a fuel injection axis collides with the cavity (25) is made small. This enables a tendency for fuel to flow out to the exterior of the cavity (25) in a cross section where the squish flow is small to be wakened, and a tendency for fuel to flow out to the exterior of the cavity (25) in a cross section where the squish flow is large to be strengthened, thereby making the conditions in which fuel and air are mixed uniform throughout the entire region of the cavity (25).
