DIRECT INJECTION TYPE COMPRESSION IGNITION INTERNAL COMBUSTION ENGINE

Title:

DIRECT INJECTION TYPE COMPRESSION IGNITION INTERNAL COMBUSTION ENGINE

Document Type and Number:

WIPO Patent Application WO/1993/000504

Kind Code:

A1

Abstract:

A direct injection type compression ignition internal combustion engine in which a collision surface (13) is formed in a cavity (7) formed in turn in the top surface of a piston (2), and in which fuel is injected from a fuel injection valve (15) toward the collison surface (13) in the form of a continuous flow of fluid. A fuel injection starting time is set at around the top dead center of compression so as to effect an initial combustion in the cavity (7). Fuel caused to collide against the collision surface (13) is taken into a squash area (23) by a reverse squash flow generated when the piston (2) lowers after it has reached the top dead center of compression, with the most part of combustion following the initial combustion being effected in the squash area (23) after the piston has reached the compression top dead center.
