Abstract: A system for controlling enriched prechamber stoichiometry includes a prechamber ignition device, and an ignition control system that includes a sensor structured to measure an amount of at least one of CO2 or O2 in a prechamber, an engine timing sensor, a fuel quality sensor, and an electronic control unit. The electronic control unit is structured to receive signals from each of the sensors and determine an air-fuel ratio of the prechamber for comparison with a target air-fuel ratio, and produce a fuel delivery signal based on the comparison.

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.
