    Abstract: A fuel introduction system introduces fuel to an internal combustion engine operating on a six-stroke combustion cycle including a first compression stroke, a first power stroke, a second compression stroke, and a second power stroke. The fuel introduction system includes a first orifice set for introducing a first fuel charge to a combustion chamber of the engine during the first compression stroke and/or power stroke and a second orifice set for introducing a second fuel charge to the combustion chamber during the second compression stroke and/or power stroke. Combustion of the second fuel charge can assist in burning particulate matter left in the combustion chamber from combusting the first fuel charge. The first and second orifice sets can be configured to differentiate the first and second fuel charges by, for example, fuel quantity or spray pattern.

    Abstract: A system includes a fuel tank and a dehydration reactor that are configured to provide a primary fuel and a pilot fuel to a power system. The fuel tank is configured to store the primary fuel and is fluidly connected to a reactor feed line and a primary fuel line provide the primary fuel. The dehydration reactor is configured to receive the primary fuel via the reactor feed line and convert a portion of the primary fuel to the pilot fuel and a byproduct. The power system is configured to receive the pilot fuel from the dehydration reactor to initiate combustion of the primary fuel. The power system also includes a cylinder with an internal piston that receives the pilot fuel and the primary fuel, contains the combustion reaction, and generates power from the combustion reaction; and contains the combustion reaction. A pilot fuel injector provides the pilot fuel to the cylinder at a first time to initiate combustion and a primary fuel injector provides the pilot fuel to the cylinder at to generate power via the power system.
