ABSTRACT:
A method and apparatus are provided for introducing a main fuel and a pilot fuel which is more readily flammable than the main fuel and which serves to ignite the main fuel into an internal combustion engine having at least one cylinder having a combustion chamber. A set of conditions are defined to constitute high load conditions on the engine and to constitute low load conditions on the engine. The load conditions are detected. At high load conditions, the main fuel is introduced into the combustion chamber prior to introducing the pilot fuel and the pilot fuel 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, and the main fuel is introduced into the combustion chamber a predetermined amount of time after the introduction of the pilot fuel.
