Method and internal combustion engine with an apparatus for introducing fuel into a dual fuel system using a hybrid of diffusion and premixed combustion process

摘要

The method involves defining a set of conditions to constitute high load conditions on the engine, and defining another set of conditions to constitute low load conditions on the engine, and detecting the load conditions on the engine. At high load conditions, the main fuel is introduced into the combustion chamber prior to introducing the pilot fuel, which is introduced into the combustion chamber a predetermined amount of time after the introduction of the main fuel. At low load conditions the pilot fuel is introduced into the combustion chamber in advance of the main fuel which is introduced into the combustion chamber a predetermined amount of time after the introduction of the pilot fuel. The main fuel is injected in a manner so that a substantial amount of it is intermixed with cylinder charged air prior to combustion.
