CYLINDER PRESSURE BASED CONTROL OF DUAL FUEL ENGINES |
摘要 |
Systems and methods for controlling operation of dual fuel internal combustion engines in response to cylinder pressure based determinations are disclosed. The techniques control fueling contributions from a first fuel source and a second fuel source to achieve desired operational outcomes in response to the cylinder pressure based determinations. |

1. A method, comprising;
operating an internal combustion engine system including an intake system connected to an engine with a plurality of cylinders and at least two fuel sources operably connected to the internal combustion engine system to provide a flow of liquid fuel to each of the plurality of cylinders and a flow of a gaseous fuel to each of the plurality of cylinders, wherein the intake system is coupled to each of the plurality of cylinders to provide a charge flow from the intake system to a combustion chamber of the respective cylinder, the internal combustion engine system further including an exhaust system; determining a pressure in the combustion chamber of at least one cylinder during a combustion cycle associated with the cylinder; determining at least one operating condition of the at least one cylinder that is based on the pressure; and adjusting a substitution rate of the gaseous fuel for the liquid fuel in response to the operating condition deviating from a target operating condition. |
