Method and apparatus for introducing fuel into a duel fuel system using the H-combustion process

Apparatus for separately injecting primary fuel and a high combustion auxiliary fuel into a combustion chamber of an internal combustion engine having at least one cylinder having said combustion chamber comprising:

• a. means for 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;
• b. load sensing means for detecting the load conditions of the engine;
• c. control means for determining the relationship of the timing of the injection of the auxiliary fuel into the combustion chamber with respect to the primary fuel in cooperation with the load sensing means to achieve a predetermined specific fuel consumption, a predetermined combustion efficiency, and a predetermined peak cylinder firing pressure;
• and
• d. means for introducing the main fuel into the combustion chamber at high load conditions prior to introducing the pilot fuel and for introducing the pilot fuel into the combustion chamber a predetermined amount of time after the introduction of the main fuel;
• and,
• e. means for introducing the pilot fuel into the combustion chamber at low load conditions in advance of the main fuel and for introducing the main fuel into the combustion chamber a predetermined amount of time after the introduction of the pilot fuel.

A diesel locomotive internal combustion engine comprising at least two cylinders, each having a reciprocating piston operatively connected to a crank and a combustion chamber, also comprising means for separately injecting a primary fuel and a high combustion auxiliary fuel into the combustion chambers of an internal combustion diesel engine comprising:

• a. means for 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;
• b. load sensing means for detecting the load conditions of the engine;
• c. control means for determining the relationship of the timing of the injection of the auxiliary fuel into the combustion chamber with respect to the primary fuel in cooperation with the load sensing means to achieve a predetermined specific fuel consumption, a predetermined combustion efficiency, and a predetermined peak cylinder firing pressure;
• and
• d. means for introducing the main fuel into the combustion chamber at high load conditions prior to introducing the pilot fuel and for introducing the pilot fuel into the combustion chamber a predetermined amount of time after the introduction of the main fuel;
• and,
• e. means for introducing the pilot fuel into the combustion chamber at low load conditions in advance of the main fuel and for introducing the main fuel into the combustion chamber a predetermined amount of time after the introduction of the pilot fuel.
