Title:
気体燃料供給内燃機関の制御方法及び制御装置
Document Type and Number:
Japanese Patent JP2006501395
Kind Code:
A
Abstract:
A method and apparatus create an environment within a combustion chamber of an internal combustion engine suitable for auto-ignition and combustion of a fuel that will not otherwise auto-ignite. Under high-load conditions, a pilot quantity of the fuel is injected in the combustion chamber of an internal combustion engine during the compression stroke of the piston. The quantity and timing of the fuel are chosen to heat an intake charge within the combustion chamber to a temperature at or above the auto-ignition temperature of the fuel by the time required for a main injection of the fuel to drive the piston during the power stroke. Generally, auto-ignition temperatures should be reached at or near top dead center of the piston. An injector design delivers fuel in manner carried out by the method.
