Abstract
Official abstract text for this publication.
A combustion chamber structure for an engine is provided. The combustion chamber structure includes a piston formed with a downward dented cavity at a central part of an upper surface thereof, and a fuel injector provided above the piston and on an extended line of a central axis of the piston, the fuel injector changing an injection timing of fuel on a compression stroke according to an operating state of the engine. A fuel injection angle of the fuel injector is designed to satisfy conditions in which the fuel is injected into the cavity and in which a fuel spray collision distance defined from a fuel injection position of the fuel injector to a collision position of the fuel with the cavity is longer than a breakup length defined from the fuel injection position of the fuel injector to a position where an initial breakup of the fuel occurs.
First claim
Opening claim text (preview).
What is claimed is: 1 . A combustion chamber structure for an engine, the engine injecting fuel on a compression stroke within a predetermined engine operating range, the combustion chamber structure comprising: a piston formed with a downward dented cavity at a central part of an upper surface thereof; and a fuel injector provided above the piston and on an extended line of a central axis of the piston, the fuel injector changing an injection timing of the fuel on the compres…
